Margrabe's model of the market assumes only the existence of the two risky assets, whose prices, as usual, are assumed to follow a geometric Brownian motion.The volatilities of these Brownian motions do not need to be constant, but it is important that the volatility of S 1 /S 2, σ, is constant.

The same holds for put options and all other simple contingent claims. The same convex combination applies also to several option greeks like Delta, Gamma, Rho and Theta. The mixture dynamics is a flexible model, as one can select the number of components according to the complexity of the smile.
For example, for bond options [3] the underlying is a bond, but the source of uncertainty is the annualized interest rate (i.e. the short rate). Here, for each randomly generated yield curve we observe a different resultant bond price on the option's exercise date; this bond price is then the input for the determination of the option's payoff.
