Lecture 1: Stochastic Volatility and Local Volatility

Lecture 1: Stochastic Volatility andLocal VolatilityJim Gatheral, Merrill Lynch Case Studies in Financial Modelling Course Notes,Courant Institute of Mathematical Sciences,Fall Term, 2002 AbstractIn the course of the following lectures, we will study why equityoptions are priced as they are. In so doing, we will apply many ofthe techniques students will have learned in previous semesters anddevelop some intuition for the pricing of both vanilla and exotic equityoptions. By considering specific examples, we will see that in pricingoptions, it is often as important to take into account the dynamics ofunderlying variables as it is to match known market prices of otherclaims. My hope is that these lectures will prove particularly usefulto those who end up specializing in the structuring, pricing, tradingand risk management of equity derivatives.

The stochastic process (1) followed by the stock price is equivalent to the one assumed in the derivation of Black and Scholes (1973). This ensures that the standard time-dependent volatility version of the Black-Scholes formula (as derived in section 8.6 of Wilmott (1998) for example) may be retrieved in the limit · ! 0.

CHAPTER 1. INTRODUCTION 7 total savings after 15 years amount to L55 S15, which yields an individual share equal to L55 S15 L70 (1.3) to each of the L70 survivors if L70 >0. By the so-called law of large numbers, the proportion of survivors L70=L55 tends to the individual survival probability 0:75 as the number of participants L55 tends to in nity. Therefore, as the

Stochastic processes are meant to model the evolution over time of real phenomena for which randomness is inherent. For example, X n could denote the price of a stock ndays from now, the population size of a given species after nyears, the amount of bandwidth in use in a telecommunications network after nhours of operation, or the amount of ...
