A course in quantitative finance, from cash flows and discounting to bonds, options, credit risk, and credit default swaps. Build intuition first, then check it with toy models, worked examples, and knowledge checks.
This course teaches the valuation of fixed-income and credit products. It
starts from signed cash flows, rates, and discounting. It then values
fixed-rate bonds, forwards, and European options, and it ends with options on
a bond and with credit default swaps (CDS). The seven parts build on each
other, and each part states which earlier parts it uses.
The chapters work in toy models. A toy model has stated inputs, and the
chapter states what the model simplifies or leaves out. A chapter states what
you will be able to do, explains the idea before the formula, and works a
numerical example. Most chapters end with a knowledge check and a model
boundary. Some chapters add an interactive lab, in which you change the
inputs and see the result change.
The course is an educational draft. It is not a pricing system, and it uses
no live market data.
Every part is a starting point. Start at Part 1 if the course is new to you.
The two learning paths go through the course in a fixed order. Both paths
assume only basic algebra, percentages and decimal notation, and integer
exponents, and both begin with the same chapter:
Cash-flow timelines and perspective.
To start at a later part, first read the parts that it requires, and the
parts that those parts require. The curriculum map shows
the same requirements chapter by chapter.
Part 1 · FoundationsCash flows, probability, rates, discounting, and no-arbitrage pricing. Requires basic algebra, percentages and decimal notation, and integer exponents.
Part 2 · BondsThe fixed-rate bond, its price from discount factors or from a yield, and its settlement. Requires Part 1. The bond-forwards chapter also requires Part 4.
Part 3 · Rates and curvesA dated discount curve and the discount factor between two future dates. Requires the discount factors of Part 1.
Part 4 · Derivative foundationsForwards and European options, from payoffs to put-call parity and lattice valuation. Requires Part 1.
Part 5 · Bond optionsEuropean options on a bond, and an option that issuer default extinguishes. Requires Parts 2 and 4. The issuer-default chapter also requires Part 6.
Part 6 · Credit riskDefault time, survival and hazard rates, recovery of par, and the value of a risky payment. Requires Part 1.
Part 7 · CDSThe premium and protection legs, the market quote and upfront, the credit curve, and quote risk. Requires Parts 1 and 6. The credit-curve chapter also requires Part 3.
Each part opens with an overview page that states what the part covers, how
it builds on the earlier parts, and the argument that runs through its
chapters. Equations, tables, diagrams, knowledge checks, and worked examples
are numbered by part and chapter, and each kind starts again in every
chapter, so equation (1.5.1) is the first numbered equation of the fifth
chapter of Part 1. Section headings are numbered the same way.
Distinguish a conventional CDS spread quote from a fixed running coupon, identify which quantity is observed and which is solved, calculate the signed upfront amount, and reverse the simplified conversion.
Separate what the CDS market shows from what a pricing model assumes or solves, read a credit curve as tenor marks plus a fitted survival curve, and distinguish transforming quotes from fitting the curve.
Measure a CDS position's sensitivity to the liquid tenor's quote by bump and reprice, then size the liquid-tenor equivalent notional and equivalent ratio that offset it.
