The difference between the two lowest strikes must be the same as the difference between the two highest strikes. [1] All four options must have the same underlying and the same expiry date. [1] At expiry, a condor's value will be somewhere between 0 and the difference between the two higher (or two lower) strike prices. [1]
In options trading, a vertical spread is an options strategy involving buying and selling of multiple options of the same underlying security, same expiration date ...
Simple payoff diagrams of the four types of ladder. In finance, a ladder, also known as a Christmas tree, is a combination of three options of the same type (all calls or all puts) at three different strike prices. [1] A long ladder is used by traders who expect low volatility, while a short ladder is used by traders who expect high volatility.
For example, a bull spread constructed from calls (e.g., long a 50 call, short a 60 call) combined with a bear spread constructed from puts (e.g., long a 60 put, short a 50 put) has a constant payoff of the difference in exercise prices (e.g. 10) assuming that the underlying stock does not go ex-dividend before the expiration of the options.
For a long position this payoff is: = For a short position, it is: f T = K − S T {\displaystyle f_{T}=K-S_{T}} Since the final value (at maturity) of a forward position depends on the spot price which will then be prevailing, this contract can be viewed, from a purely financial point of view, as "a bet on the future spot price" [ 3 ]
In options trading, a bull spread is a bullish, vertical spread options strategy that is designed to profit from a moderate rise in the price of the underlying security. Because of put–call parity , a bull spread can be constructed using either put options or call options .
The technique applied then, is (1) to generate a large number of possible, but random, price paths for the underlying (or underlyings) via simulation, and (2) to then calculate the associated exercise value (i.e. "payoff") of the option for each path. (3) These payoffs are then averaged and (4) discounted to today.
The payoff of the option, repriced under this change of numeraire, is max(0, S 1 (T)/S 2 (T) - 1). So the original option has become a call option on the first asset (with its numeraire pricing) with a strike of 1 unit of the riskless asset. Note the dividend rate q 1 of the first asset remains the same even with change of pricing.
