Fixed Income Valuation and Amortization10 min
This section covers the fundamental mechanics of bond valuation. A bond's price is determined by discounting its coupon payments and face value at the market's required rate of return (YTM). The relationship between coupon rates and YTM dictates whether a bond sells at par, premium, or discount. It also introduces perpetuities, which are valued as an infinite series of constant payments. Furthermore, the section details loan amortization, explaining how to calculate periodic installments and split them into interest and principal components.

Key Points

  • Bond Value = PV of Coupons + PV of Face Value discounted at YTM.
  • PV of Perpetuity = Payment / Discount Rate.
  • Amortization Installment is calculated using TVM keys (PV, I/Y, N, FV=0).
  • Interest Component = Opening Loan Balance * Interest Rate.
  • Principal Repaid = Installment - Interest Component.
Equity Valuation and PE Ratios15 min
This section focuses on valuing equity using Dividend Discount Models. The Gordon Growth Model (GGM) is a key tool for valuing companies with stable growth, while multi-stage models accommodate changing growth phases. The text also explains how to back-solve for implied growth or discount rates given the current stock price. Additionally, it distinguishes between Trailing and Leading PE ratios and defines Justified PE ratios based on fundamental drivers like payout, growth, and risk.

Key Points

  • GGM Formula: V0 = D1 / (ke - g).
  • D1 = D0 * (1 + g).
  • Justified Leading PE = Payout Ratio / (ke - g).
  • Justified Trailing PE = Payout Ratio * (1 + g) / (ke - g).
  • Implied g = ke - (D1 / P0).
Advanced Pricing Concepts: Additivity, Forwards, and Options15 min
The final section covers the Cash Flow Additivity Principle, which ensures no-arbitrage conditions in market pricing. It applies this logic to derive implied forward interest rates from the term structure of spot rates. Interest Rate Parity is introduced to link foreign exchange rates with interest rate differentials. Lastly, option pricing is explained using a one-period binomial model, where a hedge ratio is used to construct a risk-free portfolio to determine the option's fair value.

Key Points

  • Cash Flow Additivity: PV of a whole equals the sum of the PVs of its parts.
  • Forward Rate Calculation: (1 + S2)^2 = (1 + S1) * (1 + 1y1y).
  • Interest Rate Parity: Forward/Spot = (1 + Domestic Rate) / (1 + Foreign Rate).
  • Hedge Ratio = (Option Up - Option Down) / (Stock Up - Stock Down).
  • Option Price is derived from the value of a replicating portfolio.
