⚠️ Bond is trading at a discount — YTM will be higher than the coupon rate.
⚠️ YTM assumes all coupons are reinvested at the same rate. This is a theoretical measure — actual returns may vary. Not financial advice.

YTM is the total annualized return you'd earn if you bought the bond today and held it until maturity, assuming all coupons are reinvested at the same rate. It's the most useful single yield metric for comparing bonds.
Current yield = annual coupon ÷ current price. It ignores the gain or loss at maturity. YTM accounts for the full cash flow stream including the return of face value, so it's more accurate for total return comparison.
When market interest rates rise above a bond's coupon rate, the bond trades at a discount (below par) to compensate buyers. When rates fall below the coupon rate, the bond trades at a premium.
Modified duration estimates how much the bond's price will change for a 1% change in yield. A modified duration of 7 means the bond's price drops roughly 7% if yields rise 1%.
Dollar Value of 01 (DV01) is the dollar amount your bond position changes for a 1 basis point (0.01%) move in yield. It's a key risk metric for fixed-income portfolios.
