Question: Suppose that on any given day the annualized continuously compounded
Suppose that on any given day the annualized continuously compounded stock return has a volatility of either 15%, with a probability of 80%, or 30%, with a probability of 20%. This is a mixture of normals model. Simulate the daily stock return and construct a histogram and normal plot. What happens to the normal plot as you vary the probability of the high volatility distribution?
