(10 points) If we regress the rate of appreciation on the forward premium as shown in chapter 6, St+1 - St _ = at B Ft - St +E St St We will find that the slope coefficient S is not exactly one. We then know that the forward expectation parity does not hold well in reality. Now, let's write the rate of appreciation as the forward premium plus a remaining term. What does a negative / imply about the variance of the remaining term relative to variance of rate of appreciation
