question

You plan to purchase a company and wish to estimate the expected return on the companys equity using a three-factor model. You believe the appropriate factors are the market return, the percentage change in GNP and the oil price return. The market is expected to grow by 6 per cent, GNP is expected to grow by 2 per cent, and the oil price is expected to fall by 5 per cent. The company has betas of 0.8, 0.3 and 0.1 for the market, GNP and oil respectively. The expected rate of return on the equity is 15 percent. What is the revised expected return if the market falls by 8 per cent, GNP contracts by 0.3 per cent and the oil price grows by 9 per cent?
