Starting Delta Neutral When traders set out to gamma scalp, they create a delta-neutral position. They do so by placing an option trade and they offset the delta of the option trade by selling stock. For example, imagine a trader, Jill, buys XYZ calls that each have a 0. The position delta would be 45 -- the delta of each option 0. Based on the previous discussion of delta, that means the call position would function as if it were a stock position of 4, shares. Thus, Jill could offset her immediate directional sensitivity by selling short 4, shares of XYZ stock.
It will change because of gamma. Jill has long options calls so she has positive gamma.
So gamma will benefit her; delta will change in her favor. This recalibrating of delta as a result of gamma gives rise to an opportunity for Jill. She'll hedge as her delta changes resulting in scalping the stock. When the stock falls and her delta gets short she'll buy stock. Then when XYZ rises and her delta gets long, she'll sell stock. These scalping transactions of buying stock when it's low and selling it when it's high create a cash flow. The Theta Problem Recall that the trade off of positive gamma is negative theta. Jill's position loses value in the amount of theta each day. Imagine her theta is 0. On the contracts, her theta would be 2. That's real money.
Vega and Theta Xpwrts is a function of implied volatility. Recall that the higher the implied volatility, the higher the value of the options.
