First, we may note that (i) E{dw(t)} =0, (ii) E{dw(t)dt} = E{dw In matematica, il lemma di Itō ("Formula di Itō") è usato nel calcolo stocastico al fine di computare il differenziale di una funzione di un particolare tipo di processo stocastico. Trova ampio impiego nella matematica finanziaria . Ito's Lemma Derivation of Black-Scholes Solving Black-Scholes E cient Market Hypothesis Past history is fully re ected in the present price, however this does not hold any further information. (Past performance is not indicative of future returns) Markets respond immediately to any new information about an asset.

The stock price follows an Ito process, with drift and diffusion terms dependent on the stock price and on time, which we summarize in a single subscript Ito’s lemma is used to nd the derivative of a time-dependent function of a stochastic process. Under the stochastic setting that deals with random variables, Ito’s lemma plays a role analogous to chain rule in ordinary di erential calculus. It states that, if fis a C2 function and B t is a standard Brownian motion, then for every t, f(B t 2019-06-08 MASSACHUSETTS INSTITUTE OF TECHNOLOGY . 6.265/15.070J Fall 2013 Lecture 17 11/13/2013 .
