Long range dependence, no arbitrage and the Black-Scholes formula. (English) Zbl 1016.91053

This paper studies a stock price model driven by the sum of a Wiener process and a continuous process \(Z\) having zero generalized quadratic variation. It uses forward integrals as in the author’s paper [Math. Nachr. 225, 145-183 (2001; Zbl 0983.60054)] to define self-financing portfolios. For contingent claims which are nice functions of the terminal stock price, it is then shown that one can construct a valuation function and a hedging portfolio from a solution of the usual Black-Scholes PDE. Under additional assumptions on \(Z\), it is also shown that the model contains no arbitrage strategies within a specified class. Particular examples yield models with long range dependence.
