Question 2
We consider an example of constructing a synthetic safe asset with two risky
assets. Suppose that there are two periods: 0, and 1. We consider stocks A
and B. Neither of the two stocks pay any dividend.
In period 0, the price of stock A is S = 99.5, the price of stock B is S 94.
The one-period risk-free rate in period 0 is denoted by ro.
In period 1, there are two states: “up" and "down". State "up" occurs with
probability 0.6; State "down" occurs with probability 0.4. The prices of the
two stocks in period 1 is given by the following table.
The one-period risk-free rate in period 1 ri is 5%.
