F Flashcards
convert among holding period yields, money market yields, effective annual yields, and bond equivalent yields.
HPY, EAY, Rmm can be used as a basis to calc. other two, but remember that…
HPY is the actual return an investor will recieve if the money market instrument is held until maturiy
EAY is the annualized HPY on the basis of a 365-day year and incorporates the effects of compounding
The Rmm is the annualized yield that is based on price and a 360-day year and does not account for the effects of compounding - it assumes simple interest
EAY basis (Rmm to HPY, v versa)
“You purched a 100 k T-bill that matures in 150 days for a price of 90k. The broker who sold you the T-bill quoted the money market yield at 4.898%. Compute the HPY and EAY
Rmm basis
“You purched a 100 k T-bill that matures in 150 days for a price of 90k. The broker who sold you the T-bill quoted the money market yield at 4.898%. Compute the HPY and EAY
HPY:
Rmm to HPY: (given money market yield): .04898 (150/360) *Rmm is annualized at 360 days = %2.041
HPY to EAY: EAY = (1+HPY)^365/150 -1 (EAY is annualized at 365 days) - EAY back to HPY, simply flip the recipricol of the exponent
LEvel 1 tip: Concentrate on converting back and forth between the HPY and the other yield figures
Note: Reminder: EAY and Rmm are merely annualized versions of the HPY
Bond Equivalent Yield
BEY: refers to 2 x the semiannual discount rate, which is based on the fact that yields on US bonds are quoted as twice the semiannual rate, becase the coupon interest is paid in two semiannual payments.
Calc: Convert N’month’ yield to an effective semiannual (2xN) yield.
