Core time value formulas and fixed-income valuation5 min
This chapter applies time value of money principles to financial asset valuation and to deriving market-implied returns and growth. It begins by reviewing the present value and future value relations: FVt = PV(1 + r)^t and PV = FVt/(1 + r)^t, and their continuous-time counterparts FVt = PV e^{r t} and PV = FVt e^{-r t}. Fixed-income instruments are valued by discounting promised cash flows: zero-coupon (discount) bonds have PV = FV/(1 + r)^t; coupon bonds have PV = sum of discounted coupons plus discounted principal; annuities (level-payment instruments) use A = r PV / (1 - (1 + r)^{-t}); perpetuities use PV = PMT / r. Compounding frequency matters: periodic rate = Rs/m and PV = FV(1 + Rs/m)^{-mN}. Yield to maturity (YTM) is the internal rate of return that discounts all promised bond cash flows to current price and assumes reinvestment of coupons at the same YTM. For mortgage and amortizing loans the payment formula and amortization schedule split interest and principal each period.

Key Points

  • Present/future value relations for discrete and continuous compounding.
  • Discount/zero bonds: PV = FV/(1 + r)^t.
  • Coupon bonds priced as sum of discounted coupons and principal.
  • Annuity payment formula and perpetuity formula.
  • Compounding frequency affects periodic rate and number of periods.
Equity valuation, implied returns and growth5 min
Equity valuation is developed via dividend-discount models. A constant perpetual dividend D gives PV = D/r. Constant-growth (Gordon) model: PV = D1 / (r - g) where D1 = D0(1 + g) and r > g. Two-stage (or multi-stage) growth models decompose early high-growth periods and later stable growth; terminal (or continuing) value at transition is computed as expected dividend next period divided by (r - g_long), then discounted back. From the dividend-discount relation one can solve for implied r given price and expected dividends: r = D1/P + g. Conversely, implied growth g = r - D1/P. Price-to-earnings (P/E) ratios can be expressed in terms of payout ratio, growth, and required return: P/E = (payout)/(r - g) (forward P/E using expected next-year earnings and D1).

Key Points

  • Dividend discount models: no growth, constant growth, changing growth.
  • Gordon model PV = D1/(r - g) and inversion for implied r or g.
  • Terminal value in multi-stage models computed using D_{t+1}/(r - g).
  • P/E relates to payout ratio and r - g: P/E = payout / (r - g).
Implied returns, time-weighted vs money-weighted returns5 min
Implied returns for fixed-income instruments: given price and promised cash flows, solve IRR or YTM. For discount bonds with single principal, r = (FV/PV)^{1/t} - 1. For coupon bonds, use iterative solution (RATE/YIELD functions). Examples contrast investors purchasing at issuance vs later, decomposing multi-period realized returns and showing how price changes and reinvestment assumptions alter realized returns. Time-weighted returns neutralize cash flow timing and are preferred for manager performance evaluation; money-weighted (IRR) reflects investor's actual performance given cash flows in and out.

Key Points

  • YTM is IRR that discounts promised cash flows to price.
  • Discount bond implied return solved algebraically; coupon bonds via iteration.
  • Time-weighted returns remove cash flow timing effects; money-weighted (IRR) includes them.
Cash flow additivity, forward rates, and forward FX5 min
Cash flow additivity: the PV of a sum of cash flows equals the sum of their PVs. No-arbitrage requires economically equivalent strategies have identical PVs. Forward interest rates are implied by the term structure: (1 + r_2)^2 = (1 + r_1)(1 + F_{1,1}), so F_{1,1} = (1 + r_2)^2/(1 + r_1) - 1. Forward FX rates are linked to interest differentials (covered interest parity): F = S * e^{(r_dom - r_for)T} under continuous compounding. Examples show how deviations create arbitrage and how to compute breakeven forward rates.

Key Points

  • Cash flow additivity underpins no-arbitrage pricing.
  • Forward interest rates implied from spot yields and no-arbitrage.
  • Forward FX relates spot FX and interest rates by covered interest parity.
Option replication and binomial pricing5 min
In a one-period binomial model, option payoffs under up/down states can be replicated by forming a portfolio of the underlying asset and borrowing/lending. Solving for the replicating portfolio value and discounting at the risk-free (or appropriate) rate yields the option price. Hedge ratio (delta) = (C_u - C_d)/(S_u - S_d). Put and call replication examples show no-arbitrage prices in simple trees. Replication logic generalizes to multi-period binomial and to Black–Scholes under limiting assumptions.

Key Points

  • Replicating portfolio creates same future payoffs in both states; discount to present gives option price.
  • Hedge ratio (delta) determines units of underlying to replicate option.
  • Binomial approach illustrated for calls and puts.
Annualization, continuous compounding, and other return measures5 min
Periodic returns are annualized using (1 + R_period)^c - 1 where c is periods per year; for fractional periods use fractional exponents. Continuously compounded return r = ln(1 + R). Continuous returns add over periods: r_{0,T} = sum r_{t,t+1}. Relationship between nominal and real returns: (1 + nominal) = (1 + real)(1 + inflation). Leverage magnifies returns and losses: RL = Rp + (VB/VE)(Rp - r_D). Gross vs net returns and pre-tax vs after-tax and real returns are discussed; example computations illustrate after-tax real returns and effect of fees.

Key Points

  • Annualization formulas for converting between frequencies.
  • Continuously compounded returns are additive and r = ln(1 + R).
  • Real returns computed from nominal and inflation; after-tax real returns adjust for taxes first.
