I can't offer too much insight, sorry. But I will say the "quant" fund label is very broad. RenTec and AQR both hire PhDs and use computers to trade, but AQR offers mutual funds with daily liquidity and they publicly disclose much more info - RenTec as a private fund has more flexibility in what it can do. Correspondingly, how a fund uses risk and takes on leverage can make a big difference.
