Emanuel Derman's "The Volatility Smile" is an excellent book for those who have learned something about derivatives and now need to think on their own.

Miller take us into the weeds, but by their own accounting not too deep into the weeds.The Volatility Smile At least since the crash of 1987, the market-observed implied volatilities of European equity options have exhibited a distinct "skew" structure. Deep out-of-the-money puts generally trade at higher implied volatilities than out-of-themoney calls. An example - for options on the S&P 500 index - is shown in Figure 1.The Volatility Smile. The Black-Scholes-Merton option model was the greatest innovation of 20th century finance, and remains the most widely applied theory in all of finance. Despite this success, the model is fundamentally at odds with the observed behavior of option markets: a graph of implied volatilities against strike will typically ...This variation, known as the implied volatility "smile," is currently a significant and persistent feature of most global index option markets. But the constant local volatility assumption in the Black-Scholes theory and the CRR tree leads to the absence of a volatility smile, at least as long as market frictions are ignored.smile-consistent models (based on an arbitrage-free approach), have been pro-posed in the literature. One approach is to model the volatility as a stochas-tic process, see Hull and White (1987) or Derman and Kani (1998); another works with discontinuous jumps in the stock price, see Merton (1976).

This review paper focuses on the smile-consistent stochastic volatility models. Smile-consistent stochastic volatility models take the European options' market prices as given, and they try to explain the stochastic evolution of implied volatilities over time across strikes and maturities.Then, in the absence of a change in risk premium or an increased prob-ability of jumps, the realized volatility will be the dominant input to the estimation of the implied volatility of (high-gamma) at-the-money options.As the index moves to new levels, it is sensible to re-mark the current at-the-money implied volatility to the value of the previous at-the-money volatility, because the ...Emanuel Derman’s “The Volatility Smile” is an excellent book for those who have learned something about derivatives and now need to think on their own.
