Problem 1 (15 marks)

Suppose the return on portfolio P has the following probability distribution:

	Bear Market	Normal market	Bull market
Probability	0.2	0.5	0.3
Return on P	-20%	18%	50%

Assume that the risk-free rate is 9%, and the expected return and standard deviation on the market portfolio M is 0.19 and 0.20, respectively. The correlation coefficient between portfolio P and the market portfolio M is 0.6.

Answer the following questions:

• Is P efficient? What is the beta of portfolio P?
• What is the alpha of portfolio P? Is P overpriced or underpriced?
