We add to the portfolio by shorting w units an option with vega equal to ν A. But now our new portfolio is no longer delta neutral, instead it has a delta of −w∆ A where ∆ A is the delta of added option (could be negative). We must therefore Jun 14, 2013 · Changes in the value of an underlier are often the primary source of market risk in a derivatives portfolio, so there are two Greek factor sensitivities for measuring such exposure.
