= Consider the one-period binomial tree model seen in class with d 1/2, u = 1.5, r = 1, So = 3. there an arbitrage opportunity in this model? Can you exhibit such a strategy? = Consider the one-period binomial tree model seen in class with d 1/2, u = 1.5, r = 1, So = 3. there an arbitrage opportunity in this model?
