Not All Diversification Strategies Are Equal

The article argues that equal-weight investing is not one-size-fits-all and highlights why equal-sector strategies may offer better diversification than equal-stock approaches for investors seeking alternatives to a concentrated S&P 500. SS&C ALPS Advisors says equal-stock weighting can unintentionally overweight smaller, weaker, higher-volatility companies, while equal-sector weighting addresses concentration at the sector level and preserves exposure to leading companies within each industry. The commentary points to a Bloomberg chart showing the NYSE Equal Sector Weight Index outperforming the S&P 500 Equal Weight Index from April 2016 through April 2026. It also notes that ALPS Equal Sector Weight ETF (EQL) tracks a sector-equal approach, holds $733 million in assets, and charges a 0.27% net expense ratio. Market impact: the piece reinforces demand for diversification products and supports a relative positive case for sector-balanced ETFs over broad equal-weight strategies.
