First you started with this
When i pointed out one is CAGR and for S&P you are comparing to cumulative return, you decided took their average of entire equity fund line up then compared to S&P.
Even this is not right. You need to compare each fund to their respective stated benchmark. Their line up includes several international funds. You can not compare International to Domestic benchmark, Momentum to defensive benchmarks. Funds are given mandate and they have to operate within their mandate.
Take your stated example 1 outperforming with 9 funds with -ve return, what if the line up had 1 domestic and 9 emerging market funds. They could still outperform their respective benchmark, but overall average would still fall short of your stated benchmark of SPX.
You are entitled for your opinion. AQR is very well respected firm, where their research has made them one of the top asset manager in the world. So investors are voting with their money.
You can poke hole in their research, but your arguments are weak.
