What is a bond quote (short answer)
– A bond quote reports the market price of a bond plus key identifying details (coupon, maturity, credit rating, etc.). Prices are normally shown relative to the bond’s face (par) value so investors can quickly convert the quote into a dollar price and compare securities.
Key definitions
– Bond quote: a market listing that shows a bond’s current trading price and supplementary information needed to evaluate it.
– Face value (par value): the amount the bond will pay at maturity; in U.S. markets this is usually $1,000 (sometimes $100).
– Coupon: the fixed annual interest rate paid on the face value, expressed as a percentage.
– Yield (most often yield to maturity): the annualized return an investor would earn if the bond is held to maturity and all payments are made as scheduled.
– Bid and ask: the bid is the highest price a buyer is willing to pay; the ask (offer) is the lowest price a seller will accept. The difference is the bid–ask spread.
– Spread: the difference in yield between a bond and a reference benchmark (for example, Treasuries); often quoted in basis points (1 basis point = 0.01%).
How a typical bond quote is shown (components)
When you see a bond quote it commonly includes:
– Ticker / CUSIP: unique identifier for the bond.
– Price: shown as a percentage of par (e.g., 101.25 means 101.25% of face value).
– Yield: usually yield to maturity, shown as a percentage.
– Maturity date: the calendar date when principal is repaid.
– Coupon: the fixed annual interest rate on the bond.
– Credit rating: agency opinion of issuer creditworthiness (S&P, Moody’s, Fitch).
– Extra notes: trading venue (TRACE, EMMA), call features, or whether the quote is a pure price, yield quote, or spread quote.
Reading a bond quote — step by step
1. Identify the quote type — price-based, yield-based, or spread-based.
2. Convert price to dollars:
– If face value = $1,000, dollar price = (quote% / 100) × $1,000.
– Example: 98 → 0.98 × $1,000 = $980.
3. Compare yield with coupon:
– If price > par (premium), yield < coupon.
– If price coupon.
4. Check bid/ask and spread to assess liquidity and trading costs.
5. Check maturity and credit rating to judge interest-rate sensitivity and credit risk.
Worked numeric example (price → approximate yield)
Assume:
– Face value = $1,000
– Coupon
– Coupon (annual) = 5% → annual coupon payment C = 0.05 × $1,000 = $50
– Price = 98 → P = 0.98 × $1,000 = $980
– Maturity = 5 years
Step A — Calculate current yield (simple, one-line)
1. Current yield = annual coupon payment / price = C / P
2. = $50 / $980 = 0.05102 → 5.10%
Interpretation: current yield measures the income return based on today’s price; it ignores principal gain/loss from holding to maturity.
Step B — Approximate yield to maturity (YTM)
Use the common approximation:
YTM ≈ [C + (F − P) / n] / [(F + P) / 2]
where F = face value ($1,000), P = price, C = annual coupon, n = years to maturity.
1. Compute the parts:
– (F − P) / n = ($1,000 − $980) / 5 = $20 / 5 = $4
– numerator = C + (F − P) / n = $50 + $4 = $54
– denominator = (F + P) / 2 = ($1,000 + $980) / 2 = $990
2. YTM ≈ $54 / $990 = 0.054545 → 5.45% (approximate)
Interpretation: because the bond trades below par (discount), the YTM (total expected return to maturity) is higher than the coupon rate. This approximation assumes annual coupon payments and no embedded options (e.g., calls).
Step C — Exact YTM (conceptual)
Exact YTM is the discount rate y that solves the present-value equation for cash flows:
P = Σ (C / (1 + y)^t) + F / (1 + y)^n
For periodic (semiannual) coupons, replace C with C/2 and t with 1..2n; solve for y using a financial calculator, Excel’s YIELD function, or numerical methods (IRR). The approximation above is sufficient for quick checks but may differ slightly from the exact YTM.
Adjustments for semiannual coupons (practical note)
– If coupons are paid semiannually, convert:
– semiannual coupon = C / 2
– number of periods = n × 2
– solve for semiannual yield, then annualize (multiply by 2 for a nominal APR or convert to effective annual).
Other practical factors to remember (checklist)
– Clean vs. dirty price: bond quotes usually show the clean price (ex‑accrued interest). Actual cash paid = clean price + accrued interest.
– Bid/ask and spread: wider spreads indicate lower liquidity and higher transaction costs.
– Accrued interest formula: accrued = coupon × (days since last coupon / days in coupon period).
– Credit risk: check issuer credit rating and recent news.
– Call or put features: callable bonds can alter expected cash flows; YTM assumes no early redemption.
– Tax status and embedded options: municipal bonds or bonds with convertibility require different valuation adjustments.
– Duration and interest-rate sensitivity: longer maturity and lower coupon → higher duration.
Worked check (summary of numeric example)
– Price $980, Coupon 5% → Current yield = 5.10%
– Approximate YTM = 5.45%
– Conclusion: bond at a small discount; approximate YTM modestly above coupon.
