A vega neutral portfolio is still subject to risk. For example, in a portfolio of options maturing at different times, changes in volatility over time can dramatically affect total returns, making the portfolio sensitive to time vega. Furthermore, if the assumptions used to establish a position turn out to be incorrect, a position that is intended to be neutral can actually be risky. 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. Other options riskmanagement positions include delta neutral, gamma neutral and theta neutral.
