Safety: Performance of Low Volatility ETFs compared to S&P.

Which low volatility ETFs have promising performance compared to S&P ?

These ETFs may do better than S&P not by rising up faster, but falling down slower. Losses are big killers of long term gains, even if they don't do so well in the short term. For the Long term passive part of your portfolio, they may bring attractive returns with lower risk (drawdowns and volatility), especially relevant given that we are towards the end of a bull run.
