Dividend yield explained
Yield is the most quoted number in dividend investing and the most easily misread. It is a ratio between two things that move independently — and when it jumps, it is usually the wrong one that moved.
The formula
Dividend yield is the annual dividend per share divided by the share price, expressed as a percentage:
Yield = (annual dividend per share ÷ share price) × 100
A stock paying $0.50 a quarter — $2.00 a year — at a price of $50 yields 4%. Buy the same stock at $40 and your yield is 5%. Buy it at $80 and it is 2.5%. The company's payment never changed; only what you paid for it did.
This is the first thing to internalise: yield is a property of your purchase, not of the company. Two people holding identical shares can have completely different yields on cost. The yield quoted on a screen is simply the yield for someone buying today.
Trailing yield vs forward yield
There are two ways to fill in the "annual dividend" part of the formula, and they can differ materially.
- Trailing yield uses the dividends actually paid over the last twelve months. It is factual, but backward-looking: it includes any payment the company has since cut, and excludes a raise announced last week.
- Forward (indicated) yield annualises the most recent payment — a quarterly payer's latest $0.55 becomes $2.20 a year. It reflects the current rate, but assumes the company keeps paying it, which is an assumption, not a fact.
Neither is wrong; they answer different questions. The gap between them is itself informative. If trailing yield is well above forward yield, the dividend has been cut. If forward is well above trailing, it has recently been raised — or the company has just paid a special dividend that won't repeat, which is a classic way to end up with a badly overstated yield.
On this site, each stock page shows the most recent payment and the indicated annual dividend at the current rate, so you can compute either against whatever price you care about. We deliberately don't publish a yield figure, because it would be stale the moment the price moved.
Why a high yield is usually a warning
Because price sits in the denominator, yield rises when a stock falls. A yield that has climbed from 4% to 9% almost never means the company doubled its dividend — it means the shares halved.
And share prices halve for reasons. Often the market has concluded that the dividend itself is at risk: earnings are deteriorating, debt is rising, an end market is collapsing. The high yield is the market pricing in a cut that the board hasn't announced yet. Buy for the 9% and you may collect one more payment before it becomes 3%, on a stock that has fallen further.
This pattern is common enough to have a name — the yield trap — and it is why experienced dividend investors treat an unusually high yield as a question rather than an answer. The question is: what does the market know that this number doesn't reflect?
Our own research on dividend cuts found that they are, in aggregate, well telegraphed. Companies that cut had already seen their shares fall roughly 3% relative to the market over the preceding six months. The market rarely gets blindsided; the yield had already risen before the cut landed.
Checking whether a yield is sustainable
Yield tells you the size of the payment relative to the price. It says nothing about whether the company can keep making it. For that you need to look at what funds the dividend:
- Payout ratio. What share of earnings — or better, free cash flow — the dividend consumes. A ratio comfortably under 100% leaves room for a bad year. See the payout ratio.
- The trend in the payment itself. A dividend that has risen steadily for a decade is behaving differently from one that has been frozen for three years. A freeze is often the step before a cut.
- Balance sheet. A company borrowing to cover its dividend is not distributing profit; it is distributing debt.
- Sector norms. REITs and utilities structurally run high payout ratios and high yields. Comparing a REIT's yield to a software company's tells you about the business models, not about relative value.
Yield on cost
Long-term holders often track yield on cost — the current annual dividend divided by the price they originally paid. Hold a stock for fifteen years while it raises the payment 7% a year and a 3% starting yield becomes an 8% yield on your original outlay.
It is a satisfying number and a genuinely useful one for thinking about compounding. It is also not a valuation measure: it says nothing about whether the stock is worth holding now. The decision to keep owning something is made at today's price, at today's yield, like everyone else's.
What yield leaves out
Total return is price change plus dividends. A 6% yield on a stock that declines 10% a year is not income, it is slow liquidation. Conversely a 1.5% yield on a business compounding earnings at 12% may deliver far more. Yield is one input to a return, not a return.
It also ignores tax. The same headline yield delivers materially different cash depending on whether the dividends are qualified or ordinary, and on the account holding them.
The bottom line
Use yield to size a payment against a price, and nothing more. When it looks unusually attractive, assume the price moved rather than the dividend, and go and find out why. The payout ratio and the payment history — both of which are about the company rather than the quote — will tell you more about whether the income is going to persist.
