Consider the Black-Scholes-Merton model where the stock price of a (non-dividend- paying) stock (St)t20 with initial spot price So (today at time t = 0) is modeled by St= So e(-2)t+o-Bi (t > 0) with expected return R, volatility o> 0 and (standard) Brownian motion (Bt)t20. Compute the dynamics (stochastic differential equation) of the inverse of stock price process (t > 0). It = 1 St
