SCHD tracks the Dow Jones US Dividend 100 Index, which starts with US companies that have paid dividends for at least ten consecutive years and then ranks them on four quality measures: cash flow relative to total debt (can the company afford its payout?), return on equity (is the business actually profitable?), dividend yield (is the payout meaningful?), and five-year dividend growth (is it rising?). The strongest combined scores make the index — roughly a hundred companies, rebalanced every year.
Cash flow vs debt
Can the company comfortably afford its payout?
Return on equity
Is the business actually profitable?
Dividend yield
Is the payout meaningful next to the price?
5-year dividend growth
Has the payout been rising, year after year?
That recipe explains SCHD’s personality. The yield sits around 3–3.5% — well above the S&P 500, well below the covered-call funds — and the payout has historically grown at a high-single-digit to low-double-digit pace, because the screen keeps selecting for raisers and dropping laggards. It is deliberately light on high-flying tech, which is why it lags in roaring growth years and holds up better when dividends are what the market wants.
What SCHD is not: it is not the most income you can buy today, and it is not a bond substitute — in a bad market it falls with stocks, because it is stocks. Investors typically use it as a core holding with DRIP on, where the compounding story is the rising payout itself: modest yield now, materially larger income per share later.
Run it both ways on the SCHD calculator page — the default scenario, and a pessimistic one with the growth rates halved. If the pessimistic case still fits your plan, the optimistic one is a bonus rather than a requirement.
