| Abstract: | As fixed-income investors analyze bond markets using forward rates, so index options investors should analyze volatility markets using local volatilities. In skewed markets, such analysis shows that both the index exposure of standard options and the fair value of many exotic options differ substantially from Black-Scholes predictions. The article explains the concept of local volatility and its use. It also presents three heuristic rules that relate local and implied volatilities. |
