You estimate the Fama-French 3-factor model for IBM and obtain the following results: (a) Which of these coefficients are significantly different from zero? Interpret the signs of SMB and HML : Does IBM behave like a small or large stock? Value or growth stock? (b) Now assume that the expected returns on the 3 factors are E[rMKT]=E[rM rf]=5%,E[rSMB]=1%, and E[rHML]=2.5%. Based on the above factor loadings (beta) estimates, what is the expected excess return of IBM according to the Fama-French 3-factor model
