Assume that a three-factor APT describes the returns of all well-diversified portfolios, and that the three factors are unexpected changes in production (factor 1), a default spread factor (factor 2), and a Treasury term-spread factor (factor 3). Because of recent adverse events, over the next year, the market expects production to grow only by 1.5%, default spread to be 3.0%, and the term spread to be 1.8%. The pricing relationships for all well diversified portfolios are given by:

All investors can borrow or lend at the risk free rate of 5%. Sigma(factor₁) = Sigma (factor₂) = Sigma (factor₃) = 0.15. For simplicity, assume that the coefficient of correlation between any two factors is 0. The return process for portfolio A (which is well diversified) over the next year is:

.

1.What is the expected return portfolio A?

2.What is the standard deviation of portfolio A?

3.If production grows by 3% over the next year, the default spread falls to 2.75%, and the term spread does exactly what the market expects, what will be the return on the portfolio A?
