Executive Stock Options: Portfolio Effects
Since executives typically receive new grants of stock options (ESOs) each year, longerserving executives often have portfolios of ESOs with differing strikes and maturities. Valuation models for stand-alone ESO grants have shown that trading restrictions, which force executives to bear unhedgeable risk until the options are exercised, induce earlier exercise and hence a lower cost to sharehold...

متن کاملExecutive Exercise Explained: Patterns for Stock Options
It is well documented that executives granted stock options tend to exercise early and in a few large transactions or “blocks”. Standard risk-neutral valuation models cannot explain these patterns, and attempts to capture the exercise behavior of risk averse executives have been limited to the special case of one option.

متن کاملValuing Time-Dependent CEV Barrier Options
We have derived the analytical kernels of the pricing formulae of the CEV knockout options with time-dependent parameters for a parametric class of moving barriers. By a series of similarity transformations and changing variables, we are able to reduce the pricing equation to one which is reducible to the Bessel equation with constant parameters. These results enable us to develop a simple and ...
