EAR & APR
EAR: indicates the total amount of interest that will be earned at the end of the year (need to use powers)
APR: indicates the amount of simple interest earned in one year
Replicating a floater + value at reset
A dynamic strategy of rolling one-year bonds until the floater’s maturity and collecting the coupons along the way replicates the cash flows of the floater
(on reset dates, a floater is worth par ex-current coupon)
Two things we should not use YTM for
- measure a bond’s return (using the YTM for comparing bonds is correct only when the bonds have the same coupon and time to maturity
- a tool for choosing different bonds
Upward vs downward sloping yield curve
Upwards: economics expansion
Downwards: economic recession
Empirical violation of EH
- long-maturity bonds return more, on average, than short-term maturity bonds (since the term structure slopes upwards in general)
- excess return of long-maturity bonds over short-maturity bonds is positively related to slope of term structure…?
Direction of movements that is consistent with EMH
Steep positive slope - short rates are likely to increase
Negative slope - short rates are likely to decrease
Factors that affect the term structure
- inflation: positive inflation means that the purchasing power of money decreases -> the higher the expected inflation, the lower the demand for bonds is.
- monetary policy: open market operations, standing facilities, reserve requirements, QE
Suppose investors want to ensure a real return
They would invest in nominal bonds only if their expected returns are higher than that of real (inflation-linked) bonds
Bond prices vs. interest rates
Bond prices go down when interest rates go up and vice versa.
Macaulay duration for T-year zero coupon bond
T
Modified duration meaning
Tells us what happens to the value of a dollar invested in the portfolio for a unit change in yield
Properties of Macaulay duration
- D always decreases with coupon rate
2. D generally increases with time to maturity (but not always)
Error of duration (vs convexity)
- understates the capital gain if IR decreases
- overstates the capital loss if IR increases

CAPM assumptions
- N risky assets & riskless assets
- trading of assets is costless
- investors care only about mean & variance
- investors have the same information
- investors have a one-period horizon
Uses of CAPM
- valuation of stocks
- valuation of firms’ investments
- portfolio selection
