Abstract

This article investigates hedging efficiency of implied volatility (IV) and historical volatility (HV) for European call options on S&P500 (SPY) using Black–Scholes–Merton pricing model. We implement a five days’ hedging frequency with IV using option prices and HV using 30 days’ rolling return window. The hedging performances of implied volatility and historical volatility are measured with root mean squared error (RMSE), mean absolute error (MAE) and profit and loss (PnL) volatility. We conclude that the speed of IV increases following changes in the market and captures risk due to short-term factors better, but it generates larger errors in times of stable markets, while the HV method, with a much slower reaction, generates better results for calm markets with lower tracking errors and low frequency of rebalancing. Our conclusions lead to the proposal that the time to select between IV and HV is the market conditions and both could also offer better hedging methods when they are combined. Our analysis gives valuable input for both the comprehension of volatility and the construction of new more efficient hedging methods in equity index options.
