Problem 3 (20 Points): A. Write a macro function to calculate the Future value for a series of cash flows. B. Write a macro function to estimate the cost of equity using the: (i) Capital Asset Pricing Model (CAPM) Ri = If + Ba (I'm-If) where: If = the rate of return on risk-free securities (typically Treasuries) Ba = the beta of the investment in question I'm = the market's overall expected rate of return (ii) Fama-French Model Ri = If + Bmkt (RMRF) + Bsize (SMB) + Bvalue (HML) where: If = the rate of return on risk-free securities (typically Treasuries) Bmkt = market beta Bsize = Size beta Bvalue = value beta
