Yield

Yield is the income generated by an investment expressed as a percentage of its price, and it is one of the most fundamental concepts in finance. While the term is simple, yield comes in many forms that measure different things, and understanding these distinctions is essential for making informed investment decisions.

The most common yield types include: Dividend yield (annual dividend ÷ stock price) — a stock paying $4 annually at $100 has a 4% dividend yield. Current yield (annual coupon ÷ bond market price) — a bond with a $50 coupon trading at $980 has a 5.1% current yield. Yield to maturity (YTM) — the total return expected if a bond is held until maturity, accounting for coupon payments, price paid, and face value received. SEC yield — a standardized 30-day yield calculation for mutual funds. Distribution yield — income distributed by a fund divided by its NAV.

Yield has an inverse relationship with price that is critical to understand. When a stock or bond price rises, its yield falls (same income ÷ higher price = lower percentage). When prices fall, yields rise. This is why rising interest rates cause bond prices to decline — new bonds offer higher yields, making existing lower-yield bonds less attractive, pushing their prices down until their effective yield matches the market.

The pursuit of yield — often called "reaching for yield" — is one of the most common and dangerous mistakes in investing. When interest rates are low, investors desperate for income often buy increasingly risky assets (junk bonds, leveraged loan funds, speculative dividend stocks) to maintain their yield target. This risk-taking behavior was a major contributor to the 2008 financial crisis, when investors bought mortgage-backed securities yielding 6-7% without understanding the underlying default risk. The first rule of yield investing: if a yield looks too good to be true, it almost certainly is.
