For decades, the dividend yield has served as the default shorthand for income-oriented equity investing. It is familiar, transparent, and easily compared. But in a research paper published in October 20261, S&P Dow Jones Indices researchers Elizabeth Bebb, Rupert Watts, and Qing Li argue that dividend yield alone tells an incomplete story, and that the market has moved on.
Capital Return Has Evolved
The opening premise of the S&P Global paper is unambiguous: "the ways in which companies return capital have evolved materially over the past decade, with share repurchases becoming an increasingly significant component of capital returned by S&P 500 constituents." Buybacks, once a secondary consideration, now rival or exceed dividends in total capital distributed annually across the S&P 500. Net debt reduction adds a third dimension: by reducing leverage, a company indirectly strengthens the residual equity claim, even without a dollar flowing directly to shareholders.
Shareholder yield, as Bebb, Watts, and Li define it, captures all three: "capital return divided by float-adjusted market capitalization, where capital return is defined as the sum of dividends paid, net share repurchases and the net reduction in total debt." Including debt reduction, they note, "also helps avoid favoring companies that fund dividends and buybacks through incremental borrowing." That last point is quietly critical. A company levering up to sustain distributions is not demonstrating capital strength; it is mortgaging the future.
A Four-Part Test for Durability
High shareholder yield alone, however, can be a trap. The team notes that "a high shareholder yield may reflect strong capital returns relative to the company's valuation, but it may also result from a substantial decline in a distressed company's share price." The back-tested quintile data supports this: the highest-yield quintile produced the strongest long-term risk-adjusted return but came with elevated standard deviation and deeper drawdowns than a pure performance reading would suggest.
The S&P 500 Resilient Shareholder Yield Index responds to this problem with a composite selection score that blends four metrics: shareholder yield, five-year capital return growth, return on equity, and free cash flow to total debt. Each element is doing specific work. Capital return growth "focuses on the trajectory of distributions and balance-sheet improvement" rather than the current snapshot. ROE "complements the capital return metrics by assessing a company's ability to generate earnings from invested equity." And FCF-to-total debt "measures the extent to which a company's debt obligations are covered by internally generated cash flow, providing an indicator of financial flexibility and balance sheet resilience."
Taken together, the four metrics "seek to identify companies with strong shareholder yields that are supported by improving capital return capacity, profitable operations and financial resilience." The integration is explicit: "this integrated approach is intended to reduce reliance on any single metric and, in particular, to help distinguish sustainable shareholder returns from those associated with financially weaker companies."
What the Back-Test Shows
Across the full period from June 2000 to May 2026, the index produced annualized performance of 11.21%, outpacing the S&P 500 by 267 basis points. Risk-adjusted performance was 0.81, versus 0.56 for the benchmark. Maximum drawdown was 45.06%, materially better than the S&P 500's 50.95% decline.
The defensive profile is especially notable under stress. Across nine distinct market drawdown periods, the index declined less than the S&P 500 in six of nine, with an average decline of 16.70% versus 21.30% for the benchmark. During the Tech Bubble Burst, the index fell 20.41% versus the S&P 500's 44.73% drop. Outperformance was most consistent when it mattered most: when growth is falling and inflation is rising, the index recorded its strongest average monthly excess return of 57 basis points. The researchers find that the index "recorded its strongest excess return during periods of elevated volatility, averaging 92 bps when VIX exceeded 30."
Attribution analysis shows the outperformance was not a sector bet. Of the 904 basis points in cumulative excess return, 519 bps came from allocation effects, led by an underweight to Financials and an overweight to Consumer Staples, while 386 bps came from bottom-up stock selection. Industrials (245 bps) and Consumer Discretionary (118 bps) were the top stock-selection contributors.
The index also maintained a shareholder yield averaging 8.50% over the full period, compared to 0.78% for the S&P 500, "more than 10 times the shareholder yield of the benchmark." That differential has widened further in recent years as the S&P 500's dividend yield has compressed to historically low levels.
Five Key Takeaways for Advisors and Investors
1. Dividend yield is no longer sufficient. Share repurchases have grown to rival dividends as a capital return mechanism. Strategies anchored solely on dividend yield risk missing a substantial portion of how modern companies distribute value.
2. High yield without quality is a warning sign. The highest-yield quintile outperformed over time but carried significantly higher risk. Without profitability and cash flow filters, elevated yields often signal distressed valuations rather than financial strength.
3. Trajectory matters as much as level. Capital return growth over five years separates companies expanding their distribution capacity from those sustaining returns that may prove unsustainable under pressure.
4. FCF-to-debt is an underappreciated resilience signal. The weakest quintile on this metric significantly underperformed and experienced the highest volatility and deepest drawdowns. Internally generated cash flow relative to obligations is a material predictor of durable returns.
5. The strategy performs best when markets are most stressed. The index's outperformance was most pronounced in high-volatility and falling-growth environments, suggesting it may serve a genuine defensive function in portfolio construction, not merely as an income overlay.
