- Invesco S&P 500 Low Volatility (SPLV): it selects 100 stocks in the S&P 500 with the lowest volatility over the past 12 months (high turnover might be a problem, though)
- SPDR SSGA US Large Cap Low Volatility Index (LGLV): it selects stocks based on their trailing 5-year, rather than 1-year, price movements, and turnover is much lower as a result.
- Invesco S&P 500 High Dividend Low Volatility (SPHD): it is more selective, only consists of 50 stocks that not only have low volatility, but also historically provided high dividend yields.
- Invesco S&P 500 Quality (SPHQ): it selects the top 100 stocks within the S&P 500 with higher return on equity, stronger cash flow, and lower financial leverage, regardless of the sector.
- iShares Edge MSCI USA Quality Factor (QUAL): it also invests in high quality companies, but only relative to their peers in the same sector (therefore its makeup is more similar to that of the broader benchmark).
- FlexShares US Quality Large-Cap Index (QLC): it considers not just quality, but also valuation and price momentum when selecting stocks.
