Suppose the current portfolio shows a vega of V P, and a trader would like to short N units of options with a per-unit vega of V A. The portfolio will be vega-neutral if N = V P /V A. For example, a portfolio consists of 200 lots of $50 strike calls with a vega of 5 per unit.

Gamma controls the Delta.

$\begingroup$ Vomma for Vega is like Gamma for Delta. Positive Vomma means that a Vega-neutral position makes money both in rising and falling volatility (if the rest of the risks removed). What you are saying is Vega - long Vega means gains with rising vol and losses with falling vol. Yes I agree that max Vomma is around 15% delta (or 1 stdev). The different Greeks are: Delta, Gamma, Theta, Vega, and Rho. DELTA: It is defined as the rate of change of the option price with respect to the price of the underlying asset.

Consider a delta-neutral portfolio that has a gamma of Г P , and a traded option that has a gamma equal to Г T . The gamma and vega of a delta-neutral portfolio are 50 per $ per $ and 25 per %, respectively. Estimate what happens to the value of the portfolio when there is a shock to the market causing the underlying asset price to decrease by $3 and its volatility to increase by 4%. Vega is one of the "options Greeks" along with delta, gamma, rho and theta. These are used to measure different types of risk in options portfolios.

Also, a portfolio consisting of a stock and a single option can never be delta-neutral and gamma-neutral unless the option’s gamma happens to be zero. Gamma measures the sensitivity of a delta in relation to the underlying asset. Gamma pertains to the rate of change in Delta for a $1 change in the stock price. For example, if an option has a value of $20 and the underlying asset has a market value of $100, Delta is shown to be $0.60 and Gamma at 0.20.
