Financial Engineering - The volatility skew strategy involves arbitrage trading based on the implied volatility differences between in-the-money and out-of-the-money options. The VSI indicator is used to describe these differences, calculated as the ratio of the implied volatility of an out-of-the-money option to that of an in-the-money option. Under normal conditions, the VSI indicator fluctuates within a certain range, but significant differences in volatility ratios indicate potential arbitrage opportunities [2][3]. - The strategy's performance is closely correlated with current volatility levels. Position control signals are established based on the volatility level. If the current volatility is high and the option combination has negative volatility risk exposure, it is favorable to trade with full positions. Conversely, if the exposure is positive, only half the position should be used [4][5].
