How to read these numbers
Quick reminders for interpreting premium/discount status and rate risk.
Price vs yield
Prices move opposite of market yields. If the Fed hikes, expect bond prices to dip. When yields fall, previously issued coupons look attractive and prices climb.
Premium, discount, or par
- Premium (>100% of par): coupon > market yield.
- Discount (<100% of par): coupon < market yield.
- Par (=100%): coupon roughly equals required return.
Duration as risk shorthand
Modified duration of 7.7 means a 1% rate move should change the price by roughly 7.7%. Longer maturities and lower coupons push duration higher.
