These trades are described from the point of view of a speculator. If they are combined with other positions, they can also be used in hedging. An option contract in US markets usually represents shares of the underlying security. A trader who believes that a stock's price will increase might buy the right to purchase the stock , which is called a call option, rather than just purchase the stock itself. He would have no obligation to buy the stock, only the right to do so until the expiration date. If the stock price at expiration is above the exercise price by more than the premium price paid, he will profit.

If the stock price at expiration is lower than the exercise price, he will let the call contract expire since it is worthless, and only lose the amount of the premium. A trader might buy the option instead of shares, because for the same amount of money, he can control a much larger number of shares. The call option holder's profit per unit is. A trader who believes that a stock's price will decrease can buy the right to sell the stock at a fixed price a put option. He will be under no obligation to sell the stock, but has the right to do so until the expiration date.

If the stock price at expiration is below the exercise price by more than the premium paid, he will profit.

If the stock price at expiration is above the exercise price, he will let the put contract expire worthless and only lose the premium paid. The put option holder's profit per unit is. In his characteristic approachable style, Thomsett simplifies complex hot button issues—such as strategic payoffs, return calculations, and hedging options—that may be mentioned in introductory texts but are often underserved. The result is a comprehensive book that helps traders understand the mathematic concepts of options trading so that they can improve their skills and outcomes.

Table of Contents Frontmatter Chapter 1. Trading Goals and Objectives Abstract.

Traders improve outcomes by defining objectives in advance, based on a complete and realistic appreciation of opportunity for profit as well as risk of loss. The value of implied volatility is questionable. Many traders believe that volatility leads price, when in fact, volatility is the result of price behavior.

Volatility cannot be estimated without careful analysis of the underlying price and its behavior pattern. Closely associated with this reality is the importance of studying options strikes and their proximity to current underlying price levels and trends. A clear relationship is found between fundamental and historical volatility. The precise outcome for historical volatility is easily calculated as an exact outcome, versus the less reliable estimate of implied volatility in the option. Studies have concluded that historical volatility is more reliable than implied volatility, and that the results produced by each are similar.

A second correlation is observed between fundamental volatility and underlying stock price behavior. This leads to a deeper understanding of options risk. The relationship can be given a proximity rating in order to narrow down the selection of both companies and their stock, and options trades likely to perform above average. Developing a point system improves probabilities of success.

Several calculations assist in identifying price advantage in options contracts.

A second calculation identifies upper and lower bounds, a means for identifying finite risk levels. In pricing options, three elements of price each contain different features.

These types of premium—intrinsic, time and extrinsic value—define likely profitable outcomes for specific trades and their timing. In doing so, the additional calculations of Delta and Gamma further articulate varying degrees of risk.

Book description

A method for identifying the applicable variables in options selection is to enact side-by-side comparisons between different underlying stocks, expirations, strikes, and the moneyness of each. This logical progression of analysis is an effective method for selecting options and specific strategies. Dividends are complex as part of an options analysis. This feature affects overall profitability as well as accurate calculation of net return. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Asked 4 years, 4 months ago. Active 4 years, 4 months ago. Viewed times. So, what is the example that gives us an arbitrage? And I was wondering whether the problem counts the case when we sell the option, the option was exercised and we HAVE TO buy the stock at overprice to pay back to the option holder. If this is indeed the case, my setup above for the final profit function is still valid I think, but why it gives me 2 contradictory cases?
