1. Consider the Black-Scholes stock process dSt = rStdt +oStdW7, where W* is a standard Brownian motion under the risk-neutral measure Q* associated with the risk-free bond numeraire. A European contract pays Vr = log ST K on maturity date T. (a) Derive the valuation formula for this contract. (b) Derive the delta (A) and (L) of this contract. 1.
