Now suppose that the manager misestimates the beta of Waterworks stock, believing it to be 0.5 instead of 1.4. The standard deviation
of the monthly market rate of return is 9%. If he holds a $5,000,000 portfolio of Waterworks stock. The S&P 500 currently is at 2,000
and the contract multiplier is $50.

b. What is the probability of incurring a loss on improperly hedged portfolio over the next month if the monthly market return has an
expected value of 1% and a standard deviation of 9%? The manager holds a $5 million portfolio of Waterworks stock, and wishes to
hedge market exposure for the next month using 1-month maturity S&P 500 futures contracts. The S&P 500 currently is at 2,000 and
the contract multiplier is $50. Assume the risk-free rate is 0.2% per month. (Enter your answer as percentages and not as a numbers,
