The expected price for AMS at the end of the year is $48.45. What is its beta? ( 3 marks) b. Tony is buying a stock with an expected perpetual dividend of $40 but is unsure of its risk. If Tony thinks the beta of the stock is 0.8, when the beta is really 1.3, how much more will he offer for the stock than it is truly worth? [Hint: Value of perpetual cash flow =CF/r] (7 marks )
