GDP (G) 2%

Unemployment (U) 3%

You determine that the return on Stock B is generated by the model: r = 9% + 0.8G + 1.2U + e a) Use the APT (Arbitrage Pricing Theory) to calculate the equilibrium rate of return on Stock B. The risk-free rate is 3%. b) Is Stock B underpriced or overpriced? Explain. (Explanation Required)
