Need help solving question 1! thank you 1) An analyst estimates the following CAPM Model for ECN Inc. [Enter % as whole number, i.e. 10% is 10]. (RECN - Rf) = 2+ 1.55(Rm - Rf) a) Suppose the market premium is expected to be 12% for the next year. If ECN Inc. has a current return of 20% and the risk-free rate is 1%, is this stock over- or under-valued. Assume the estimated model is true. b) A different analyst believes that macroeconomic factors, particularly monetary policy matters. To capture that she includes the federal funds rate (FFR) in her CAPM-based model. She estimates the following. [Enter % as whole number, i.e. 10% is 10]. (RECN - Rf) = 1.5 + 1.40(Rm - Rf) - 0.25(FFR) Using the same information from part a) and the fact that the federal funds rate is expected to be 1%, is ECN Inc. over- or under-valued? C) Based on the model estimated in part b) would news that the Federal Reserve is conducting open market purchases like be good or bad for shareholders of ECN Inc?
