Episode Summary "What's the yield?" is a deceptively simple question that often leads to a dangerous trap. At any given second, a single bond can have three different numbers correctly labeled as its "yield". This episode untangles these figures to explain why a high advertised yield is sometimes an illusion, how to avoid the "yield trap" in marketed income products, and why the most commonly quoted number is often the least useful to your actual portfolio.
Key Concepts
- Coupon Rate: The fixed interest rate printed on the contract. Because it is a percentage of par value rather than your purchase price, it only tells you the cash flow, not your actual investment return.
- Current Yield: The annual coupon divided by the current market price. While it accounts for what you paid, it completely ignores the principal repayment at maturity. This understates returns on discount bonds and dangerously overstates them on premium bonds.
- Yield to Maturity (YTM): The complete, annualized return if you buy today and hold until maturity, factoring in all coupon payments and the final principal return. It is the standard comparable metric used by professionals, but it relies on the flawed assumption that you will be able to reinvest every coupon at that same rate.
A Tale of Three Yields (The $900 Discount Bond)
Consider a $1,000 face value bond with a 5% coupon and 5 years to maturity, trading at a discount price of $900 due to rising market rates:
- Coupon Rate: 5.00% ($50 annual cash flow).
- Current Yield: 5.56% ($50 / $900).
- Yield to Maturity: 7.47% (capturing the $50 coupons plus the compounding $100 capital gain at maturity).
On a discount bond, current yield always understates your true return. Conversely, on a premium bond (e.g., an 8% coupon bought at $1,150), current yield overstates your return because it ignores the built-in $150 capital loss you will take at maturity.
The Distribution Yield Trap
Income funds often market an attractive "distribution yield". However, if the fund's distribution is much higher than the YTM of its underlying holdings, you are likely receiving a Return of Capital (ROC)—which is simply your own money being returned to you. In Canada, ROC is not taxed immediately, but it reduces your Adjusted Cost Base (ACB), triggering a much larger, delayed capital gains tax bill when you eventually sell the fund.
Complications & Yield to Worst
- Yield to Call: For callable bonds that the issuer can redeem early, you must calculate the yield to the earliest call date. Prudent investors look at Yield to Worst, which is the lower of YTM and Yield to Call.
- Pre-Tax Reality: Quoted YTM is a pre-tax, pre-broker spread number. Because bond interest is fully taxable at your marginal rate in Canada, holding them in non-registered accounts will meaningfully reduce your true return.
