	Options Table \| Exercising an Option \| American Options
		When the option buyer (or holder) decides to exercise, the writer of the option is assigned an obligation to fulfill the terms of the contract.
		The mechanics of matching an exercising option holder with an assigned option writer is handled behind the scenes by the options clearing corporation.
		Traded options that you'll find quoted are American in nature, although you'll find that early exercise of such an option usually doesn't make a lot of sense (as for why, that topic's coming).

	American Options In Iraq
		Americans were horrified when about 2,700 people were killed in the attack by al-Qaida terrorists on the World Trade Center on September 11, 2001.
		The second option is "Vietnamization." In Vietnam, America inherited from the French both a government and a large army.
		The best America might gain from this option is a fig leaf to hide defeat; the worst, in a rapid collapse, would be humiliating evacuation, as in Vietnam.

	Global Derivatives v3.0 - American Options
		Geske and Johnson (1984) give an accurate approximation for an American put option by considering it as a series of Bermudan options, with the value of the American option given when the number of exercise dates for the Bermudan option tends to infinity or an infinite series of multivariate normal terms.
		Even though implementation of the binomial model for American options and beyond is fairly simple, the major disadvantage of using the model is that it often requires a large number of nodes to achieve a decent accuracy.
		For options with a known finite number of jumps during its life, method of lines can be used to numerically solve the problem; see Meyer (1998), and finite differences is also often used (particularly explicit FD) to evaluation the differential equation.

	:: Quantnotes.com :: Fundamentals ::
		American options are different to European style options (Vanillas) in that the contract buyer has the right to exercise the option at any time before maturity (t=T).
		The freedom to exercise an American option whenever the holder wishes introduces a boundary problem to solving the Black-Scholes equation as done before for vanillas.
		We know that a fair no-arbitrage value of the option at time t will either be its present payoff value or the discounted expectation of the possible values from time t to T depending on which one is greater.

	American Options Pricing
		An American Option is an option which can be exercised at any time up to and including the expiry date of the option.
		This added flexibility over European options results in American options having a value of at least equal to that of an identical European option, although in many cases the values are very similar as the optimal exercise date is often the expiry date.
		The early exercise feature of these options complicates the valuation process as the standard Black-Scholes continuous time model cannot be used.

	NNT's Blog: American Options --Please Do Not Talk About Them
		So many "rigorous" research papers have been involved in the “exact” pricing of American options, though within model when in fact their most interesting attribute is that they benefit from the breakdown of models.
		If in all scenarios option A is worth at least the same as option B and, in some scenarios can be worth more than option B, then it is not the greatest idea to sell option A and buy option B at the exact same price.
		To conclude from these examples, the American option is extremely sensitive to the interest rates and their volatility.

	TheStreet.com: American Home Options Attract Interest
		According to one floor trader at the Chicago Board Options Exchange, the bulk of the volume on those calls was the result of two fairly large institutional trades coming from two separate houses.
		But today there was no takeover talk to accompany the options activity, so the investors could be betting on some other news to fuel the stock.
		If the stock doesn't move in the next three days, the option most likely won't be exercised, expiring worthless while the holder will be forced to eat the cost of the premium.

	American Bankruptcy Institute \| ABI Consumer Bankruptcy Reform Forum Summary and Report on Options
		There was active discussion of this option with some participants indicating some questions that had to be addressed prior to any consensus being reached on this concept.
		Point 3 of the options was discussed in depth, and there were concerns expressed that the deletion of the various debts would, in some cases, leave an empty file; a term utilized in the industry to indicate that a person has no credit history.
		Under this option the court would have the power, on motion of a creditor or realproperty lessor, to issue an in rem order that would make the automatic stay inapplicable to particular property in a subsequent bankruptcy case.

	TIMING: AMERICAN CALL OPTIONS PROGRAM WITH FOCUS ON REAL OPTIONS (Site not responding. Last check: )
		This Excel application performs the real options analysis for an opportunity to invest in a project, which is view as a finite lived American call (real) option, with time to expiration T established by legal terms (as in petroleum upstream) or by an estimative of expected time for competition entry (Kester, 1984).
		Third, it calculates the probability of option exercise and, conditional to the the option exercise, the conditional expected time of option exercise, that is, the expected first hitting time for the simulated sample paths to reach the threshold curve conditional to option exercise occurrence.
		Without operational options, and for the regime of concessions in the petroleum case, the value of the project is a linear function between V and P, but not proportional as in the previous case.

	Options FAQ: Basics
		A: A stock option is a contract that gives the owner the right, but not the obligation, to buy or sell a particular stock at a fixed price (the strike price) for a specific period of time (the expiration date).
		A: A call is an option contract that gives the owner the right to buy the underlying stock at a specified price (its strike price) for a certain, fixed period of time (until its expiration).
		Another difference is long stock options must be paid for in full, whereas a futures contract may only require a small percentage of the value of the trade be deposited in cash (referred to as initial margin).

		An options on a futures contract is like an options on a common stock in a sense that it the holder of the options has the right but not the obligation to buy (in case of call) or sell (in case of put) the underlying asset at the exercise price of the options.
		In their work on pricing the stock options, Black and Scholes[2] first pointed out, that a riskless portfolio consisting of stock options and certain ratio of stock can be formed and this riskless portfolio must earn a return of risk free interest rate.
		The key insight into the analytic approximation to price American futures options is that, if the partial differential equation applies both to European and American options, it also applies to the early exercise premium, that is the difference between the American and European options[3, 4].

		The options universe is populated by many contrarians who believe strong action in one direction is a sign that a cycle is ending and that the stock will soon behave in the opposite manner.

	Tesi - International thesis/dissertation - American Options' valuation methods: testing and comparison
		In problems with free boundaries, the boundary conditions must be sufficient to determine both the solution of a partial differential equation, and the position of the free boundary.
		The first Partial Differential Equation (PDE) ever used in options’ valuation problem was presented by Black and Scholes (1973), in their seminal paper concerned with the valuation of European-style options and was improved by Merton (1973a) in order to include constant proportional stock dividend yields.
		In addition, analytical expressions for the price of the American options have been found but there is no easily computable formula available.
