Hendriksson and Merton (1981) and Dybvig and Ingersoll (1982) for example show that non-linear pay offs limit the applicability of the SR as a performance measure. Goetzm

entury Bachelier's work was largely forgotten. The use of random walks in finance was rekindled and ultimately led to the option pricing formulae of Merton, Black and Scholes. Unfortunately the random walk process has been removed from it's many body background, and individual prices are treated as mov
