How Dividend Indices Are Constructed
If an index pays a lot of dividends, is it unconditionally good? Dividend indices are built in two broad ways, and the 'high-yield-only' side hides a trap.
Two Construction Methods
There are two representative ways to build a dividend index.
(1) High-yield method: You pick stocks with a 'high current dividend yield.' Since dividend yield = annual dividend ÷ share price, you line them up in order of yield.
(2) Dividend-growth / aristocrats method: You hold stocks that have 'steadily raised dividends over a long time.' The criterion is not what the current yield is, but the 'track record' of raising the dividend every year.
The Aristocrats Criteria
The strictest example is the S&P 500 Dividend Aristocrats index. Among S&P 500 stocks, it includes only companies that have raised dividends every year for 25 years or more. As of 2026, about 69 companies qualify.
Raising dividends for 25 straight years is hard to sustain unless you are a solidly excellent company. So this index mainly gathers mature, financially robust companies.
Interestingly, aristocrats are generally not 'high-yield stocks.' Because a company that raises dividends for a long time tends to see its share price rise too, the dividend yield (%) itself tends to actually be lower.
The number of constituents (about 69) and the criterion (25+ consecutive years of dividend increases) are based on S&P Dow Jones Indices methodology and can change over time. This is not a recommendation of any particular index or product.
Beware the Dividend Trap
The high-yield method carries a trap called the 'dividend trap.'
Dividend yield is dividend ÷ share price. But this value also grows when the share price plunges. In other words, many stocks with unusually high yields look that way not 'because they pay a lot,' but 'because their share price has fallen a lot.'
Such companies often carry high debt, an excessive payout ratio (dividend relative to earnings), and slow growth, and they may end up cutting the dividend. Then the yield and the share price collapse together. So judging by the 'yield number' alone is dangerous.
常见问题
Q. Is a higher dividend yield a better index?
No. A large part of a high yield may be an illusion created by a falling share price (the dividend trap). A method that holds companies that have steadily raised dividends tends to be more stable in dividend continuity, even if the yield number is lower. It is a difference in what you prioritize.
Q. Do dividend indices have no losses?
No. Dividend stocks are still stocks, so they fall along with down markets, and if dividends are cut, the share price and the dividend can shrink at the same time. A dividend is not a shield that prevents loss of principal.
