Buried in the back pages of the financial press last October was a story about the sale of his mutual fund company, O’Leary Funds, to Canoe Financial, an investment firm run by former Dragons’ Den cast member and entrepreneur Brett Wilson. O’Leary had launched his funds with great fanfare back in 2008, introducing them to viewers on his Business News Network (BNN) show, SqueezePlay . Before the cameras, wearing a natty navy-blue suit and matching azure tie, O’Leary resembled a proud father with a new infant as he explained to co-host Amanda Lang how his fund was designed to produce yield on a monthly basis. “You got to pay Daddy,” he declared, “because my wife costs a fortune, my kids cost a fortune. I need dough and I need dough every month. You got to pay Daddy number one.” In those days, O’Leary’s star was ascending.

He was one of the so-called “Dragons” on Dragons’ Den , which was becoming a bonafide Canadian hit. The following year he and Lang moved their daily business show over to the CBC, renamed The Lang & O’Leary Exchange . O’Leary’s popularity and persona as a business guru soon drove investors to his mutual funds, with O’Leary Funds roaring to as much as $1.5-billion in assets (and probably more). O’Leary boasted of being an investing whiz, with access to the movers and shakers in the business and political worlds — those ties giving him unique insider knowledge. The reality was quite different. O’Leary was not even licensed to manage or invest other people’s money. Instead, he hired Connor O’Brien, a former Wall Street investment banker, to run O’Leary Funds. Moreover, by 2012, the funds were in trouble, falling to $1-billion in assets by the end of that year. This past fall, when he finally sold his company to Canoe, the funds were down to $800-million in assets. This was due to redemptions — investors pulling their money out because of the funds’ performance. “The majority of the funds performed poorly for an extended period of time and the majority of (Bay Street) brokers refused to sell any new funds,” says Mark McQueen, CEO of Wellington Financial LP, a $900-million Bay Street finance firm and one of O'Leary's long-time critics. “It’s not personal. The industry lives and dies on performance.” Yet the demise of the O’Leary Funds is, in fact, just the latest in a series of failures in Kevin O’Leary’s business career.

While O’Leary recently grabbed headlines with his promise to invest $1-million in Alberta if premier Rachel Notley stepped down, and is toying with running for leadership of the federal Tory party, these stunts overshadow a history of ineptitude as a businessman.

O’Leary is unquestionably a media star: He has written best-selling books, been a fixture on at least four televisions shows, including the current ABC hit program Shark Tank, revels in making outrageous statements, and crafted an image as the “mean” Dragon, able to reduce inventors to tears with putdowns like “this is the worst idea I have ever heard in my life it’s so bad!” But what exactly is O’Leary’s business experience? Born in Montreal in 1954, O’Leary had ambitions of being a photographer. Instead, he did an MBA at the University of Western Ontario. After business school, he set up a television production company that produced shows for people like Don Cherry. From watching Cherry, O’Leary learned that it was important never to be boring or small on TV. By 1983, O’Leary saw the potential in the emerging software and personal computer industries. He formed SoftKey Software Products Inc.

in the basement of his Toronto home, convincing computer companies to bundle his software into their products. SoftKey moved to Boston and focused on the booming field of educational software. By 1993, it was trading on Nasdaq and had revenues of $110-million—and a loss of $57-million. The company grew by making a string of acquisitions. SoftKey’s most prominent takeover was of San Francisco-based The Learning Company (TLC). Prior to the sale, TLC hired the Center for Financial Research and Analysis (CFRA), a forensic accounting firm, to examine its suitor’s financials. CFRA alleged that SoftKey may have overstated its earnings by bundling various general and administrative costs into write-offs. CFRA was also unhappy with SoftKey’s decision to fire its auditor, Arthur Andersen, after the accounting firm found deficiencies in the company’s internal controls. CFRA noted that SoftKey’s audit committee “holds several questionable members, including the CEO… as well as an outside member associated with two public companies charged with financial improprieties and another member who is a paid consultant to the company.

” Yet SoftKey’s acquisition of TLC went through, and SoftKey adopted the TLC name. By 1996, TLC had 3,000 employees and was the biggest educational software company in the world. It continued to grow via acquisitions, driving revenues up over $800-million. But SEC filing shows that TLC suffered net losses of $376-million in 1996, $495-million in 1997 and $105-million in 1998. Moreover, TLC’s accumulated deficit topped $1.1-billion by the end of 1998. That same year, toy giant Mattel Inc. made a takeover bid for TLC, without doing proper due diligence. Desperate to reverse a steep slide in the company’s stock price, Mattel CEO Jill Barad seized on educational software as a driver of future growth. The takeover shocked many, largely because TLC was seen, according to software-industry analyst Sean McGowan, as a well-known “house of cards” that was burdened with tired brands—not helped by the fact that O’Leary had slashed R&D from 24 down to 11 percent of expenditures. “There was a lot of TLC inventory out there that was not moving very well,” McGowan says.

“They pumped up the sales by repackaging and distributing to convenience stores and drugstores.” Indeed, TLC was later accused in a shareholders’ lawsuit and by a Mattel executive of “stuffing the channels”—shipping product at the end of a quarter and recording it as revenue, even though much of the merchandise would be returned. “Stuffing the channels was part of the business back then,” says a former TLC sales rep based in California. In the end, Mattel purchased TLC for about $4-billion in the spring of 1999. O’Leary took over as president of Mattel’s new TLC digital division. Weeks after the sale, CFRA produced a critical report on Mattel, claiming TLC was already experiencing collapsing revenue, a surge in receivables and a deterioration of operating cash flow. In the third quarter of 1999, Mattel expected profits of $50-million from the TLC division. Instead, it was a loss of $105-million (the next quarter losses rose to $206 - million), which wiped out more than $2-billion in shareholder value in one day, as the company’s share price slid from nearly $17 to $11.69. In short, O’Leary had sold Mattel a turkey. One investors' lawsuit says O’Leary cashed in his Mattel shares just before the losses were announced when the stock was at its peak, pocketing almost $6-million. In November of 1999, O’Leary was fired, six months into a three-year contract. Four months later, Mattel’s CEO, Jill Barad, was forced out too. “There is nothing I can say to gloss over how devastating The Learning Company’s results have been to Mattel’s overall performance,” Barad said as she went out the door.

Mattel hired Bernard Stolar, a video-game executive, to see if he could salvage TLC. “It was an absolute disaster,” he says. In 2000, Mattel handed over its multi-billion-dollar acquisition to another firm for a mere $27-million and a share of its future profits. Mattel’s purchase of TLC was later labeled by Businessweek magazine as one of “the Worst Deals of All Time.” Shareholders launched a class-action lawsuit, naming O’Leary as a defendant, accusing him of insider trading and of being part of a scheme to obscure TLC’s financial state. While O’Leary denied the allegations, in 2003, Mattel settled the lawsuit for $122-million—considered a “mega-settlement” at the time. O'Leary has blamed Mattel's management for the problems with the TLC division, not his own involvement. While O’Leary’s actions cost Mattel’s investors hundreds of millions, he netted $11.2-million between his severance package and sale of his Mattel stock. Sued for wrongful dismissal. After getting canned by Mattel, O’Leary’s business career sputtered and meandered. In 2003, O’Leary invested in a self-storage company called StorageNow Holdings Inc., which he learned about from Reza Satchu, a Toronto entrepreneur. Satchu’s high-school acquaintance, Jonathan Wheler, had a background in real estate and saw that a lot of money could be made by building self-storage warehouses in accessible locales.

Wheler had even found a perfect piece of land in Toronto to erect such a facility. According to court documents, O’Leary put in about $500,000 and ended up with almost 13 percent of the company. In the summer of 2003, the Toronto land was purchased and, for a cost of $5.2-million, StorageNow’s first self-storage facility was built and opened in the spring of 2004. But the relationship among the three men deteriorated. Wheler oversaw building the Toronto facility and finding other plots of land to construct similar warehouses. Eventually, he negotiated a deal with the Satchus and O’Leary to divide up the company’s eventual profits. In a $10-million wrongful dismissal lawsuit, Wheler contends that Satchu and O’Leary arbitrarily altered the agreed-upon compensation deal, reducing his cut of the profits substantially. A further deal related to profits derived from the Toronto facility was finalized in 2004. But in April of 2005, Wheler claims he met with O’Leary who told him that this agreement was “too rich” to Wheler and what had been agreed upon was “simply no longer available”, according to Wheler’s lawsuit. O’Leary told Wheler his pay and compensation arrangements would be cut back.

The following month, Wheler was terminated. Wheler believes that once O’Leary and Satchu realized how profitable StorageNow was going to be, they pushed him out of the business. In a defense statement, Satchu and O’Leary claim Wheler was let go because he was inexperienced and lacked business acumen and fell behind schedule. Despite such characterizations, Wheler went on to develop a series of other self-storage units across Canada with another company using his original concept and became a millionaire on paper. O’Leary and his partners soon were out-maneuvered by their competitors. A competing company, InStorage Self Storage Inc., blew by them, growing so rapidly they gobbled up StorageNow in 2007. There were other miscues for O’Leary, too. In 2004, he was appointed to the board of Environmental Management Solutions Inc. (later called EnGlobe Inc.), an Ontario waste management firm. Soon afterwards, the board fired the company’s CEO. But the company’s leadership was unable to arrest a decline in its fortunes brought on by an overambitious acquisition program the stock price slid from close to $4 to 3.5 cents during O’Leary’s term of almost five years as a director. “I have had some great successes and great failures,” O’Leary said in a 2012 interview.

“I think every entrepreneur has. I try to learn from all of them.” O'Leary becomes a TV stereotype. In 2003, O’Leary talked his way into a job onto TV at BNN, partnering up with Amanda Lang on SqueezePlay , a daily business show. O’Leary was made for television, having soaked up the lessons learned from Don Cherry years earlier. He was the sort of person who would bring a box of dog biscuits to the set and howl if he thought a certain stock was a “dog”. But O’Leary also revealed his ignorance of the markets too. In the early aughts, Bay Street began peddling income trusts to investors. But Al Rosen, Mark Rosen and Diane Urquhart, experts on investment products, concluded income trusts shared characteristics of Ponzi schemes, with many destined to fail. In 2005, they produced a report saying 50 of the top income trusts were overvalued by almost 30 per cent. Yet Al Rosen recalls O’Leary championing income trusts on his TV show. Rosen says he went on BNN and argued with O’Leary about the subject.

“He’s an ignorant man,” says Rosen, one of Canada’s leading forensic accountants. “He was trying to kill us every time. We would see each other and almost spit on each other.” In 2006, O’Leary was cast on Dragons’ Den for its first season, taking on the role as the resident asshole. He was the sort of person when an inventor burst into tears after being criticized by the Dragons, would say, “Money doesn’t care. Your tears don’t add any value.” Henry Mintzberg, the Cleghorn professor of management studies at McGill University, believes O’Leary’s depiction of a business leader is pejorative. “Pitbull (executives) don’t add anything at all,” he said in an interview with this reporter back in 2012. Mintzberg said in the US there’s been the emergence of the “cult of heroic leadership” within corporations. “The tendency there…

is to attribute any success of the company to one person,” he remarked. But Mintzberg said companies function best when CEO’s recognize that companies are collaborative efforts and they show flexibility and emotional health. O’Leary, on the other hand, “is obviously an arch narcissist,” noted Mintzberg. “I don’t know how he manages his companies, but his stereotype is dysfunctional.” Dragons’ Den became a huge hit. Yet one of the myths of the show is that the deals struck by the Dragons on TV turn into real investment. In reality, only a minority of deals actually materialize. Moreover, Tracie Tighe, the show’s executive producer, once said O’Leary is “tight with his wallet” and closed only one or two deals a year. Indeed, O’Leary had a history of rarely investing with entrepreneurs and of denigrating sound projects. When Rachel Mielke, a jewelry-maker based in Regina, appeared on the show in 2008 seeking $200,000 for a 20 percent stake in her jewelry company, Hillberg & Berk, she told the Dragons that her company was valued at $1-million, a sum O’Leary openly derided. “Kevin, right from the get-go, said ‘This is a bad idea',” Mielke recalled in an interview in 2012.

“He didn’t really understand the industry.” Rachel Mielke photo from Hillberg and Berk website. In the end, Dragon Brett Wilson agreed to back her company, which shot to sales of $5-million by 2014. “Within a couple of years it was quite clear that we had surpassed the valuation that I went to Dragons’ Den with,” said Mielke. Even one of O’Leary’s success stories is not all what it cracks up to be. Wendy Johannson and Claudia Harvey invented a utility glove for women and needed $50,000 when they went on the show in 2009 for their company, DigIt Apparel Inc. On-air O’Leary agreed to give them the money in return for three percent of royalties. After the show, they eventually gave him 10 percent of the company. But the $50,000 never materialized. “When he said he’d like to have ten percent for $50,000 I thought that would be a cash injection, I thought that was money in the bank for us,” said Harvey in an interview in 2012, “When it came down to it… that wasn’t the case.” Instead, O’Leary offered them a line of credit at an interest rate higher than what the banks offer, which DigIt didn’t touch. “He’s never actually given us any money,” said Harvey at that time, although the two women were happy with his contribution to the company by opening doors to retailers. O’Leary told the Globe and Mail in 2012 that Johannson and Harvey wanted to use the money for inventory, which he didn't think was a good use of his money. He said he was proud of what the pair had achieved.

The rise and fall of O'Leary Funds. By 2008, having painted himself as a business guru, O’Leary felt it was time to cash in on his new-found fame and start another business. That summer, he announced the creation of his own mutual fund company, O’Leary Funds, despite not having a background in investing other people’s money or a broker’s license, and having denigrated mutual funds on TV. In the end, O’Leary would be the hood ornament to woo investors he hired former Wall Street investment banker Connor O’Brien to be the portfolio manager. One of the first things O’Leary said was he wouldn't “grind the capital” of investors, meaning he would not pay back to investors their very own principal to meet dividend demands (as opposed to generating dividends as a result of astute investing). The funds took off. By 2010, O’Leary was hoping his funds would hit $5-billion in assets within three years. Yet it was not long afterwards that some sharp-eyed experts on Bay Street found evidence that, in fact, O’Leary Funds was paying out dividends to investors with their very own cash – in other words, grinding their capital. “The issue is not do other people grind their own capital, it’s that he said he doesn’t do it,” says Mark McQueen, CEO of Wellington Financial. “And I found half a dozen of his funds where he had.” By 2012, investment advisers were pulling their money out of the O’Leary Funds simply because they were not performing as well as O’Leary had touted. And the funds continued to leak over the next three years before O’Leary finally folded his tent last fall, selling the entire business to Brett Wilson's Canoe Financial. Meanwhile, O’Leary’s television career also began to flag.

In 2014, he left CBC and Dragons’ Den and The Lang & O’Leary Exchange to become a gadfly at CTV. His profile in Canada has dimmed considerably since. In the end, O’Leary succeeded in becoming a millionaire. But more so because he learned how to turn himself into a celebrity and not because of his business acumen.

Lest we have happen in Canada what has happened in the US (electing a Donald Trump), we need to see this article re-published regularly so Canadians can get the message about what Kevin O'Leary is really about. We also need to remind Canadians how Donald Trump got elected and, conversely, how to stop Kevin O'Leary and the likes of him from gaining power here: Get out and vote!

About 50% of Americans assumed that Trump would lose, Hilary would win, and that holding back their vote would be their way of saying they were not enthused with either candidate. Trump won because too many Americans counted on the rest of the country to make the decision for them. Lord knows where the US is headed now because Trump has no idea himself. We have a great country led by competent and trustworthy people like Justin Trudeau. Let's keep it that way. Art, were you in the educational software business in the 80's and 90's? You may remember that Bonnie and I were as well. This guy seemed to be skilled at turning a respected software business, TLC, into a mess, as I recall. I strongly agree with your post. Donald Trump went through. Donald Trump went through four bankruptcies. Look at him now. Looking at Donald Trump - my. Looking at Donald Trump - my opinion is he is bankrupt of ideas - morals - and integrity. He has not released his financial information or tax records. Could it be he has a few billion dollars in a line of credit which is overdrawn on assets worth a lot less??

The Black-Scholes Model was developed by three academics: Fischer Black, Myron Scholes and Robert Merton. It was 28-year old Black who first had the idea in 1969 and in 1973 Fischer and Scholes published the first draft of the now famous paper The Pricing of Options and Corporate Liabilities . The concepts outlined in the paper were groundbreaking and it came as no surprise in 1997 that Merton and Scholes were awarded the Noble Prize in Economics. Fischer Black passed away in 1995, before he could share the accolade.

The Black-Scholes Model is arguably the most important and widely used concept in finance today. It has formed the basis for several subsequent option valuation models, not least the binomial model. What Does the Black-Scholes Model do? The Black-Scholes Model is a formula for calculating the fair value of an option contract, where an option is a derivative whose value is based on some underlying asset. In its early form the model was put forward as a way to calculate the theoretical value of a European call option on a stock not paying discrete proportional dividends. However it has since been shown that dividends can also be incorporated into the model. In addition to calculating the theoretical or fair value for both call and put options, the Black-Scholes model also calculates option Greeks. Option Greeks are values such as delta, gamma, theta and vega, which tell option traders how the theoretical price of the option may change given certain changes in the model inputs. Greeks are an invaluable tool in portfolio hedging. Black-Scholes Equation. The price of a put option must therefore be: Black-Scholes VBA. Function dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) dOne = (Log(UnderlyingPrice ExercisePrice) + (Interest - Dividend + 0.5 * Volatility ^ 2) * Time) (Volatility * (Sqr(Time))) Function NdOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) NdOne = Exp(-(dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) ^ 2) 2) (Sqr(2 * 3.14159265358979)) Function dTwo(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) dTwo = dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) - Volatility * Sqr(Time) Function NdTwo(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) NdTwo = Application.

NormSDist(dTwo(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend)) Function CallOption(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) CallOption = Exp(-Dividend * Time) * UnderlyingPrice * Application. NormSDist(dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend)) - ExercisePrice * Exp(-Interest * Time) * Application. NormSDist(dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) - Volatility * Sqr(Time)) Function PutOption(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend) PutOption = ExercisePrice * Exp(-Interest * Time) * Application. NormSDist(-dTwo(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend)) - Exp(-Dividend * Time) * UnderlyingPrice * Application. NormSDist(-dOne(UnderlyingPrice, ExercisePrice, Time, Interest, Volatility, Dividend)) You can create your own functions using Visual Basic in Excel and recall those functions as formulas within your chosen workbook. If you want to see the code in action complete with Option Greeks, download my Option Trading Workbook. The above code was taken from Simon Benninga's book Financial Modeling, 3rd Edition . I highly recommend reading this and Espen Gaarder Haug's The Complete Guide to Option Pricing Formulas . If you're short on option pricing formulas texts, these two are a must. From the formula and code above you will notice that six inputs are required for the Black-Scholes model: Underlying Price (price of the stock) Exercise Price (strike price) Time to Expiration (in years) Risk Free Interest Rate (rate of return) Dividend Yield Volatility. Out of these inputs, the first five are known and can be found easily. Volatility is the only input that is not known and must be estimated.

Black-Scholes Volatility. Volatility is the most important factor in pricing options. It refers to how predictable or unpredictable a stock is. The more an asset price swings around from day to day, the more volatile the asset is said to be. From a statistical point of view volatility is based on an underlying stock having a standard normal cumulative distribution. To estimate volatility, traders either: Calculate historical volatility by downloading the price series for the underlying asset and finding the standard deviation for the time series. See my Historical Volatility Calculator. Use a forecasting method such as GARCH. By using the Black-Scholes equation in reverse, traders can calculate what's known as implied volatility. That is, by entering in the market price of the option and all other known parameters, the implied volatility tells a trader what level of volatility to expect from the asset given the current share price and current option price. Assumptions of the Black-Scholes Model. The original Black-Scholes model did not take into account dividends. Since most companies do pay discrete dividends to shareholders this exclusion is unhelpful.

Dividends can be easily incorporated into the existing Black-Scholes model by adjusting the underlying price input. You can do this in two ways: Deduct the current value of all expected discrete dividends from the current stock price before entering into the model or Deduct the estimated dividend yield from the risk-free interest rate during the calculations. You will notice that my method of accounting for dividends uses the latter method. A European option means the option cannot be exercised before the expiration date of the option contract. American style options allow for the option to be exercised at any time before the expiration date. This flexibility makes American options more valuable as they allow traders to exercise a call option on a stock in order to be eligible for a dividend payment. American options are generally priced using another pricing model called the Binomial Option Model. The Black-Scholes model assumes there is no directional bias present in the price of the security and that any information available to the market is already priced into the security. 4) Frictionless Markets. Friction refers to the presence of transaction costs such as brokerage and clearing fees. The Black-Scholes model was originally developed without consideration for brokerage and other transaction costs. 5) Constant Interest Rates. The Black-Scholes model assumes that interest rates are constant and known for the duration of the options life. In reality interest rates are subject to change at anytime.

6) Asset Returns are Lognormally Distributed. Incorporating volatility into option pricing relies on the distribution of the asset&rsquos returns. Typically, the probability of an asset being higher or lower from one day to the next is unknown and therefore has a 5050 probability. Distributions that follow an even price path are said to be normally distributed and will have a bell-curve shape symmetrical around the current price. It is generally accepted, however, that stocks &ndash and many other assets in fact &ndash have an upward drift. This is partly due to the expectation that most equities will increase in value over the long term and also because a stock price has a price floor of zero. The upward bias in the returns of asset prices results in a distribution that is lognormal. A lognormally distributed curve is non-symmetrical and has a positive skew to the upside. Geometric Brownian Motion. The price path of a security is said to follow a geometric Brownian motion (GBM). GBMs are most commonly used in finance for modelling price series data.

According to Wikipedia a geometric Brownian motion is a &ldquocontinuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion".

SHAKEEL AHMED June 10th, 2017 at 11:02am. Black Scholes modelformulaequation is very complicated. Some calculator based on it is very useful. Using this calculator, I have observed something. I have taken data like this. Call option, spot price=110,strike price=100,risk free interest=10%,expiry time=30 days, implied volatility=30%,but it reduces daily @1%.All datas are imaginaries. Only theoretical datas of option premium are derived. Analysis, on 10th day, premium drops from 11.31 to 10.61=0.70,on 20th day, premium drops from 10.61 to 10.30=31,on 30th day, premium drops from 10.30 to 10.02=0.28.If option is in 10% of in-money, it is profitable from 1.31 to 0.02 anywhere.1st 10 day, volatility is good, if direction is ok, profit will be @0.10.Last 10 day, volatility is low, if direction is ok, profit will be @0.03.Result, use in-money option, trading in 1st 10 days of 30 days movement, keep direction in your favour. True direction is real winning formula, not BS-formula, i think so. Peter March 8th, 2017 at 10:59pm. Are you using the file black-scholes-excel.

xls? It works fine for me. have you "enabled" the content when opening the document? Anonymous March 2nd, 2017 at 7:50am. Your calculator is not calculating correctly for stocks so kindly fix it. Peter February 28th, 2016 at 6:32pm. Matt February 27th, 2016 at 8:51pm. Hello, I am trying to figure out what to input in the market price with an employee stock option when the strike price is $12.00, but the stock is not yet publically traded and therefore there is no stock price to input. Can the Black Scholes equation be used in this case. Dennis April 24th, 2015 at 2:30am. let's say IV of 24, Call value is 5, Put value is 5. IV of 12, Call value is 2.5, Put value is 2.5. IV of 0, both have zero value. (since the stock is assumed not to move and generate value for ATM options). Peter January 5th, 2015 at 5:13am. Bruce January 4th, 2015 at 3:46pm. Should the option price equal the IV times the vega?

Peter March 4th, 2014 at 4:45am. Satya March 4th, 2014 at 3:15am. Do you have models for the BS model only or you have them for other models like the Heston-Nandi or the Hull-White Models? If you do, could you share them? i need them for a my project. Peter April 26th, 2012 at 5:46pm. Ah ok, no worries, glad it worked out. Mario Marinato April 26th, 2012 at 7:05am. Hi, Peter. When I entered the various possible values they all gave me the same fair price. Peter April 25th, 2012 at 10:29pm.

Hi Utpaal, yes, you can use whatever price you like to calculate the implied volatility - just enter the closing prices in the "market price" field. Peter December 18th, 2011 at 3:53pm. Hi JK, you can find spreadsheets for pricing American options on the binomial model page. Utpaal December 17th, 2011 at 11:55pm. Thanks Peter for the excel file. Is it possible to have the implied volatility calculated based on the closing option price. I currently type the implied volatility which is not accurate. I do get accurate option closing price. Hope you can help. Thanks.

jk December 16th, 2011 at 7:57pm. still working on spreadsheet to price American option trading? Peter December 10th, 2011 at 5:03am. You mean the multiplier? This doesn't effect the theoretical price at all - it just changes the hedge ratio, which in this case you would just multiply by 10. MIKE December 9th, 2011 at 2:52pm. What happens to this formula if it takes 10 warrants to get 1 common share? Peter November 2nd, 2011 at 5:05pm. Hi Marez, are you pricing a stock option or an employee stock option? Can you give me more details please? I'm not sure exactly what long term incentive payments mean in this case.

How much are the payments etc? marez November 1st, 2011 at 10:43pm. Exercise Price 0.85. Today's Date 2112011. Expiry Date 30072013.

Available on the app store. Peter July 12th, 2011 at 11:48pm. Hi Paul, yes, seems that you will have to calculate Black Scholes from scratch using Apple Numbers. I've never used it before - is it a scripting language? Can you use my spreadsheet on Excel running on the iPad? Paul S July 12th, 2011 at 3:57pm.

The formula that doesn't work in Numbers is: B12=call strike price. B16=days to expiration. For Puts the formula is: B18=days to expiration. Peter July 11th, 2011 at 7:17pm. Hi Paul, there's no official formula for implied volatility as it's just a matter of looping through the Black Scholes Model to solve for volatility. However, if you want to see the method I have used you can check out the VBA code provided in my option trading workbook. Paul S July 11th, 2011 at 10:40am. Peter March 23rd, 2011 at 7:56pm. Mmm. let me go back to my books and see what I can discover.

Bob Dolan March 23rd, 2011 at 6:39pm. The example given was a stock that had a 0.5 probability of 95 and at 0.5 probability of 105. How do you establish the binary points and probabilities thereof for any given security? How you link 'research' to an Excel model is an open question. I mean, that's the fun of it. Bob Dolan March 23rd, 2011 at 5:59pm. Hey: 'Once more into the fray'. Peter March 23rd, 2011 at 5:01pm. Thanks for the great comments Bob! Do While (High - Low) > 0.0001. If CallOption(UnderlyingPrice, ExercisePrice, Time, Interest, (High + Low) 2, Dividend) > Target Then. High = (High + Low) 2. Else: Low = (High + Low) 2. ImpliedCallVolatility = (High + Low) 2. Bob Dolan March 23rd, 2011 at 3:46pm. "Stock prices rarely follow theoretical models however, so I suppose that is why the authors did not attempt to include any projections." * Black-Scholes assumes a log-normal distribution of stock prices over time. * But, sometimes, prices are determined by discrete events law-suits, regulatory approval, patent approvals, oil discoveries.

In these cases, a binary or bipolar distribution of future stock prices is a better model. * When future stock prices are better represented by a binary distribution, there may be probability arbitrage to be had if an option is priced assuming a long-normal distribution. * The longer the time frame, the more likely that GBM progressions do not apply. SOMETHING will happen. If the possibility of that something can be foreseen, probability arbitrage is possible. And here I am on your web site. Bob Dolan March 23rd, 2011 at 3:23pm. Back to the "reversed" Black-Scholes algorithm and sorry to find your site a year late . Manually, I use a binary search to get an approximation of the IV needed to produce a given option price. It's actually a two-step process: Step One: Guess at the IV say, 30 and adjust the guess until you have the IV bracketed.

Step Two: Iterate a binary search -- each time making the 'guess' half-way between the brackets. Peter February 8th, 2011 at 4:25pm. JL February 8th, 2011 at 9:06am. Peter February 7th, 2011 at 6:16pm. JL February 7th, 2011 at 4:53pm. Peter January 23rd, 2011 at 8:01pm. That's right, they're not the same, so it's up to you what method you use. BSJhala January 21st, 2011 at 9:30am. Peter January 20th, 2011 at 4:18pm. Hi BSJhala, if you want to use trading days then you can no longer reference a 365 day year you would need to make your interval 4 260. Also, in the actual VBA code for Black and Scholes you would need to change the other references to a 365 day year. BSJhala January 20th, 2011 at 9:06am. I am not clear on your comment on time diff to be used. Peter January 19th, 2011 at 4:44pm.

If it is the standard Black and Scholes Model then you would use calendar days as the formula will use 365 in the calculations. You can, however, modify the formula yourself and use your own trading day calendar of days. BSJhala January 19th, 2011 at 11:05am. What should be the time(in years). Should it be simply the date difference between today date and expiration date. Or it should be the trading days difference between today and expiration date. Peter December 5th, 2010 at 5:03pm. Thanks for the feedback Tony! Tony December 4th, 2010 at 11:19am. I've working with both your historical volatility and Black Scholes sheets. Thank you for these tools. They are well written, very fast and I sincerely appreciate your level of technical detail. 1. What date should be used for option expiration? The Friday date or the Saturday date?

For example expiration dates are currently 12172010 for Friday and saturday when all is settled is 12182010. Peter October 13th, 2010 at 12:44am. Yes, you just set the Dividend Yield to the same value as the Interest Rate. This will make the forward price used for the calculation the same as the base price but still use the Interest Rate to discount the premium. Paul October 12th, 2010 at 8:05pm. Does this spreadsheet correctly price options on european futures? Peter September 30th, 2010 at 11:08pm. Not yet - but working on it. Gric September 30th, 2010 at 9:33pm. Do you have the "Binomial Option Model" for American Style Options somewhere? Peter April 8th, 2009 at 7:05am. Helen April 7th, 2009 at 2:53pm. What will be the best way to calculate the implied volatility on options. Doing the backward of the Black-scholes model?

Admin March 22nd, 2009 at 6:36am. For American style options you would use the Binomial option pricing model. My spreadsheet currently doesn't price American options. only European options. I plan to add a Binomial model soon. JT March 18th, 2009 at 8:08am. One more question. From reading your site, which is fantastic by the way, it seems that this "pricing" method is mainly used for Euro style options. What source of pricing model would you use for American style options? Admin March 18th, 2009 at 4:43am.

JT March 17th, 2009 at 12:53pm. Stupid question. Is the theoretical price that is calculated using this method, the "max" price you should purchase this option at? Say the option price was 1.30 for a call with a strike of 2.50 and the theoretical price is 1.80. Would that make it a "good" buy? Admin February 1st, 2009 at 3:45am. Hadi AK January 31st, 2009 at 12:53am. " The volatility of an option really determines how likely that contract will be in, at or out-of-the-money by the expiration date. "
