Yeah but Renaissance is funny because they have 2 funds. The Medallion fund which only has employee money makes the amazing returns, while the normal fund for pension funds barely outperforms the market.
Except there are far more funds that already do that (even if their count is in the minority), so their sheen wears off.
Oh wait, there have been some years the normie fund actually underperformed the market, while the Medallion fund exceeded its expectations. So much that investors got real pissed (around 2018 iirc), and that's how the separation of funds structure actually came in the financial media spotlight.
