Yield to Maturity • Interest rate that equates the PV of bond’s future payments with current price • Assumes: • Bond is held to maturity • All coupon and principal payments made in a timely manner • Coupons are reinvested at YTM • YTM is a “promised” yield
Realized Yield • Rate of return actually received on investment at end of holding period • Can be interpreted as expected return if done ex-ante • To find RY: • Find FV of all coupon payments as of end of HP. Use proper reinvestment rate • Add FV to selling price (or par) of bond (TW) • Find compounded rate connecting orig. price with terminal value
Convertible Bonds • “Vanilla” Bond plus option to convert to fixed number of shares of common • Conversion Ratio = # shares per bond • Conversion Price = Par/CR • Conversion Value = Share Price x CR • Conv. Bond Value = Pure Bond Value + Option Value
Duration and Immunization • Price risk and Reinvestment rate risk • Duration is an index of a bond’s price sensitivity to interest rate fluctuations • Can be used to forecast interest rate driven price fluctuations for bonds or portfolios. • ==> Powerful risk management tool! • If Duration = Holding Period, you’re immunized from interest rate risk
