The European call option price from the model is a convex and increasing with respect to the initial underlying asset price. Assume underlying asset prices follow a generalized geometric Brownian motion, it is true that option prices increasing with respect to the constant interest rate and volatility, so that the volatility can be a very important factor in pricing option, if the volatility process σ (t) is constant (with σ (t) =σ for any t ) satisfying σ _1 ≤ σ (t) ≤ σ_2 for some constants σ_1 and σ_ 2 such that 0 ≤ σ_ 1 ≤ σ_ 2. Let C_i(t, S_t) be the price of the call at time t corresponding to the constant volatility σ_ i (i = 1,2), we will derive that the price of call option at time 0 in the model with varying volatility belongs to the interval [C_1(0, S_0),C_2(0, S_0)].
