Valuation of Common Stock Value of an asset: PV of expected future CFs Need to estimate: (1) Stream of expected CFs (2) The required rate of return Valuation for one period: P0 P1 + D1 R = (P1 - P0 + D1)/ P0 P0 = (P1 + D1) / (1 + R)
Multi-period Valuation P1 = (P2 + D2) / (1 + R) after successive substitutions, P0 = Dt / (1 + R)t Dividend Payment Patterns $ time
Constant Dividends P0 = D / R Constant Growth Dt = Dt-1(1 + g) P0 = D1 / (R - g) Supernormal growth P0 = Dt (1+G)/ (1 + R)t + Dm+1/(R-g)(1+R)m where G = growth rate during non normal growth period m = non normal growth period

Index Arbitrage F ---------- = S - PV of dividends, interest (1 + Rf) Suppose Rf = 4%, Dividend yield = 2% F = 5500 S= 5000 5500 5000x0.02 ------------ = 5288.46 5000 - ------------ = 4903.85 (1 = 0.04) (1 = 0.04) Purchase index at 5000 and sell them at delivery. Sell index at F, and sell T bills for 5000 that mature on the delivery date. Net cash flow is 0. At delivery date: Sd + 0.02x(5000) + (5500 - Sd) - 1.04(5000) 100 + 5500 - 5200 = 400 profit F must be 4903.85
