Using the table below, calculate the Sharpe ratio of a portfolio with 80% allocated to security B and 20% allocated to security D. Assume a 3% risk-free rate. Hint: your text also calls the Sharpe ratio the reward-to-variability ratio.

Time	A, %	B, %	C, %	D, %	Mkt, %
1	18.56	18.23	12.82	12.43	14.48
2	15.27	18.24	-5.82	13.45	5.99
3	14.12	14.71	12.58	4.32	12.41
4	-1.57	-6.56	-7.43	-9.54	-4.48
5	13.16	9.12	12.45	12.21	13.41
6	12.22	16.34	12.54	6.12	14.32
