That is, the value of an option is due to the convexity of the ultimate payout: one has the option to buy an asset or not in a call; for a put it is an option to sell , and the ultimate payout function a hockey stick shape is convex — "optionality" corresponds to convexity in the payout. Thus, if one purchases a call option, the expected value of the option is higher than simply taking the expected future value of the underlying and inputting it into the option payout function: the expected value of a convex function is higher than the function of the expected value Jensen inequality. The price of the option — the value of the optionality — thus reflects the convexity of the payoff function[ clarification needed ]. This value is isolated via a straddle — purchasing an at-the-money straddle whose value increases if the price of the underlying increases or decreases has initially no delta: one is simply purchasing convexity optionality , without taking a position on the underlying asset — one benefits from the degree of movement, not the direction.

When finer pricing is required one can systematically improve these formulas by using the more sophisticated models for G developed conundruums the Appendix and by adding the quadratic and higher order terms in the expansion 3.

We re in hot competition with another bank over a deal. The most widely offered are interest rate caps and floors. Faculty of Mathematics and Informatics. How wrong are we? Accordingly call-put parity should be used to evaluate in-the-money caplets and floorlets as a CMS swap payment plus an out-of-the-money floorlet or caplet.
