1)For American option, when risk free interest rate increase, will it
increase the possibility of early excises?
2)For best of two options, you buy one option, which will give you the best
payoff between two underlying options. For example,for a best put option,
two stocks A (A0 =100) and B( A0=100), strike =100, After time T, A became
80, B became 110, then you got 20, if A became 80, B became 70, you got 30.
The prices of put option for A and B are 4 and 3, respectively. Please
pricing the best two option, what's bound of this option? When the
correlation between A and B change, how will it affect the option price?
3) \sum (N from 0 to infinity) N^2*a^N. a = constant
4) The variance of \integration ( t from 0 to T) sigma(t)dW .
5) When the volatility increase, how the Gamma will change?
6) How to sort?
