Options Trading: The Hidden Reality v PRAISE "Having attended many options seminars I can honestly say that The Ri$k Doctor Webinars have been revolutionary to my options education. Unlike many other so called "options gurus" you do not try to attract people by promising them astronomical returns in fact you almost say the opposite...which is that if I am not prepared to put in the work to educate myself about the pitfalls in options trading it can be a very expensive mistake and I should better forget about trading options altogether. This was the first time I had heard anyone say this to me. The bottom line is that as an ex-market maker and trader you have practiced what you preach......unlike many people out there who have never traded but are more than happy to sell people courses on how to trade. .The way you examine, dissect and manage your risk in your trades has given my trading a significant edge. The weekly Webinars provide a great interactive platform to discuss and review new and old trades directly with you every week! I only wish I had found out about you sooner. In the past I have paid a lot more money to learn a lot less than what you have taught me.” THANK YOU! Tharma London, England “When I think back to my first discussion with Charles in 2001, I like to think that I had "Bambi Legs" as an options trader. I had worked as a clerk on an options floor, attended the expensive seminars, and had a decent grasp of the fundamentals. I had also gone nowhere in 2 years of trading my account and was getting frustrated. What followed for the next several years was a robust education in defining my trading self. From understanding the synthetic relationships inherent in options positions, to managing myself as a trader, Charles was critical in my development. The biggest takeaway for me to this day lies in the fact that Charles was the first teacher or coach who didn't set me up for failure by giving me unrealistic profit expectations. New traders need to define themselves, their risk tolerance, and what strategies mesh with those characteristics. If you've got baseless profit expectations, you'll never find these critical attributes. Charles always had me think about my positions and adjustments constantly in the present by asking: "If I had no position on right now, what would I want." Having a professional in my corner like Charles gave me the confidence to truly discover my trading personality and potential. I don't think I'd be trading for a hedge fund had I not worked with Charles. Don't find yourself asking Coulda Woulda Shoulda!” Justin California ©1996-2006 Charles M. Cottle [email protected] vi Praise “My goal this past year was to master and gain a deeper understanding of options. I am a practicing physician and a trader. It was a stroke of luck to come across the Ri$k Doctor, Charles Cottle, a true genius of options. RD’s approach to options brings to mind a series of analogies and similarities to the field of medicine as follows. As a medical doctor uses the CAT Scan or MRI to view potential human disease at the tissue or submicroscopic level, the Risk Doctor’s laser-like perception sees below the surface of an option strategy and reveals its true nature. “Primum non nocere” (first do no harm) is one of the most important dictums taught about patient management. Similarly, in his Webinars, the Ri$k Doctor teaches traders to first see and limit downside risks, while developing profitable option strategies, with and without an underlying stock or contract. He does this by teaching his followers to “card up” simple and complex options positions and then to use a variety of synthetic tools to see the true nature and position risks before entering a trade. Floor traders, whom RD has also instructed, sometimes use these very same valuable tools. Lastly, as a surgeon shows how to handle complications, so the RD teaches how to adjust to changing conditions in the real market on an ongoing basis. In the ongoing RD3 Webinar series, the Ri$k Doctor teaches by example, following the market real-time on a day-by-day basis and then posting his adjustments for each strategy as the market moves. He ultimately throws his followers into the fray and challenges each of them to construct an option strategy and make adjustments on their own that are appropriate for the perpetually changing market. In this unique scenario, his students have the opportunity of experiencing an almost real-live market trading experience, of putting their egos and emotions on the line, and then of learning from mistakes and oversights without risking hard-earned money. It’s as real as can be! For those who are serious about perfecting their option trading skills, RD’s Webinar series is like an exciting roller-coaster ride through the ups and downs of the options markets. I do not know of any other place that offers such a unique market ride. It is a sensational training experience!” Murph, MD New Jersey www.RiskDoctor.com www.RiskIllustrated.com Options Trading: The Hidden Reality vii PREFACE WHY ANOTHER OPTIONS BOOK? Dear Fellow Trader / Investor / Hedger, I wrote this book so that you will come to understand that options are either for you or they are not. For those beginners who understand basic options material, this is a good starting point. For those readers who are having problems trading options, this book will help you to determine where the problems lie, and whether you may be successful with options, or whether you should stay away from them. My mom, dad and most of my relatives don’t trade options because options are not for them. I have a cousin who trades options. He came to work for me when he left college. I am going to teach you the same way that I taught him. By learning how to avoid the pot holes and surviving long enough to put together a personal game plan, he has gone on to be one of the most exceptional options traders that the industry has ever known. Experience in the markets will teach you more than I will, just as it taught my cousin and thousands of other people who I have shared this content with over the last 25 years. It starts here and it can end here too, without losing a nickel because you will be able to answer the question, “Are options for me?” There is a lot of material in this book from my first book, “Options: Perception and Deception” (OPD), which was geared towards professional Market Makers who provide liquidity to the markets by bidding and offering every strike and month. My second book, “Coulda Woulda Shoulda” (CWS) kept a lot of OPD, but added content necessary for retail investors because it was given to clients of an electronic brokerage firm which I co-founded. “Options Trading: The Hidden Reality” merges the information in each of those books, because retail type traders, are now hungry for Market Maker techniques, and are much more sophisticated than industry leaders (exchanges and brokerage houses) give them credit for. Most of the people reading this book know something about puts and calls. To be able to trade puts and calls profitably, one needs a full grasp of the concepts. The market takes no prisoners. It simply deletes those who do not have enough knowledge and/or are hesitant to make decisions. You may be wondering how this book is different from other books on options trading. The essence of my educational work is to demonstrate where investors contradict themselves.

  • (NSE), India, Using Box Spread Arbitrage Strategy
    Gadjah Mada International Journal of Business - September-December, Vol. 15, No. 3, 2013 Gadjah Mada International Journal of Business Vol. 15, No. 3 (September - December 2013): 269 - 285 Efficiency of S&P CNX Nifty Index Option of the National Stock Exchange (NSE), India, using Box Spread Arbitrage Strategy G. P. Girish,a and Nikhil Rastogib a IBS Hyderabad, ICFAI Foundation For Higher Education (IFHE) University, Andhra Pradesh, India b Institute of Management Technology (IMT) Hyderabad, India Abstract: Box spread is a trading strategy in which one simultaneously buys and sells options having the same underlying asset and time to expiration, but different exercise prices. This study examined the effi- ciency of European style S&P CNX Nifty Index options of National Stock Exchange, (NSE) India by making use of high-frequency data on put and call options written on Nifty (Time-stamped transactions data) for the time period between 1st January 2002 and 31st December 2005 using box-spread arbitrage strategy. The advantages of box-spreads include reduced joint hypothesis problem since there is no consideration of pricing model or market equilibrium, no consideration of inter-market non-synchronicity since trading box spreads involve only one market, computational simplicity with less chances of mis- specification error, estimation error and the fact that buying and selling box spreads more or less repli- cates risk-free lending and borrowing. One thousand three hundreds and fifty eight exercisable box- spreads were found for the time period considered of which 78 Box spreads were found to be profit- able after incorporating transaction costs (32 profitable box spreads were identified for the year 2002, 19 in 2003, 14 in 2004 and 13 in 2005) The results of our study suggest that internal option market efficiency has improved over the years for S&P CNX Nifty Index options of NSE India.

  • How Options Implied Probabilities Are Calculated
    No content left No content right of this line of this line How Options Implied Probabilities Are Calculated The implied probability distribution is an approximate risk-neutral distribution derived from traded option prices using an interpolated volatility surface. In a risk-neutral world (i.e., where we are not more adverse to losing money than eager to gain it), the fair price for exposure to a given event is the payoff if that event occurs, times the probability of it occurring. Worked in reverse, the probability of an outcome is the cost of exposure Place content to the outcome divided by its payoff. Place content below this line below this line In the options market, we can buy exposure to a specific range of stock price outcomes with a strategy know as a butterfly spread (long 1 low strike call, short 2 higher strikes calls, and long 1 call at an even higher strike). The probability of the stock ending in that range is then the cost of the butterfly, divided by the payout if the stock is in the range. Building a Butterfly: Max payoff = …add 2 …then Buy $5 at $55 Buy 1 50 short 55 call 1 60 call calls Min payoff = $0 outside of $50 - $60 50 55 60 To find a smooth distribution, we price a series of theoretical call options expiring on a single date at various strikes using an implied volatility surface interpolated from traded option prices, and with these calls price a series of very tight overlapping butterfly spreads. Dividing the costs of these trades by their payoffs, and adjusting for the time value of money, yields the future probability distribution of the stock as priced by the options market.

  • Risk Management Strategies for Cattlemen
    RISK MANAGEMENT STRATEGIES FOR CATTLEMEN Kurtis Ward – President/CEO www.kisokc.com As a former agricultural loan officer, I witnessed first-hand the effects that the Dairy Herd Buyout Program had on the Cattle Market of 1986. During this time, I became intrigued by cattlemen who used some form of risk management (Futures, Options, Forward Contracting, etc.) as compared to those who did nothing but speculate on the cash market. It didn’t take long to observe which group made better financial and marketing decisions (perhaps that “hedging stuff” that my college professors were teaching was really important after all). This market event caused my loan officer career to be transformed into a new profession as a commodity futures broker who specialized in risk management strategies for cattlemen. However, my naïve belief back then was that everyone else was having this “illumination” about cattle hedging at the same time. In the 1980’s, it was said that less than 5% of cattlemen were involved in risk management. Fifteen years later, things haven’t changed much which is quite surprising when you look at the total dollars now at risk in any cattle operation. After what we’ve seen during the cattle market of the past two years, I truly believe that cattlemen cannot afford to be just cattlemen any longer. Rather, they must first be “businessmen” who incidentally invest their, time, money and livelihood in a cattle operation. Therefore, the purpose of this article is to quickly review the basics of several risk management strategies in a way that is very simplistic so that the foundational hedging precepts can be easily understood.

  • 11 Option Payoffs and Option Strategies
    11 Option Payoffs and Option Strategies Answers to Questions and Problems 1. Consider a call option with an exercise price of $80 and a cost of $5. Graph the profits and losses at expira- tion for various stock prices. 73 74 CHAPTER 11 OPTION PAYOFFS AND OPTION STRATEGIES 2. Consider a put option with an exercise price of $80 and a cost of $4. Graph the profits and losses at expiration for various stock prices. ANSWERS TO QUESTIONS AND PROBLEMS 75 3. For the call and put in questions 1 and 2, graph the profits and losses at expiration for a straddle comprising these two options. If the stock price is $80 at expiration, what will be the profit or loss? At what stock price (or prices) will the straddle have a zero profit? With a stock price at $80 at expiration, neither the call nor the put can be exercised. Both expire worthless, giving a total loss of $9. The straddle breaks even (has a zero profit) if the stock price is either $71 or $89. 4. A call option has an exercise price of $70 and is at expiration. The option costs $4, and the underlying stock trades for $75. Assuming a perfect market, how would you respond if the call is an American option? State exactly how you might transact. How does your answer differ if the option is European? With these prices, an arbitrage opportunity exists because the call price does not equal the maximum of zero or the stock price minus the exercise price. To exploit this mispricing, a trader should buy the call and exercise it for a total out-of-pocket cost of $74.
