The S&P 500 Quality Index selects the top 100 stocks from the S&P 500 universe ranked by a composite quality score built from three equally weighted components: return on equity, accruals ratio, and financial leverage. That's it. No momentum tilt, no dividend screen, no size bias. Just a systematic

After inflation, that figure drops to roughly 7.0–7.3%. Both numbers matter, but which one matters more depends en
The S&P 500 rolling 10-year return has ranged from roughly -3% annualized (ending 2009) to over 19% annualized (ending 1999), according to Morningstar's historical equity data.
