If you are Renaissance Medallion, 5%/44%. But it helps if you can return in the 40s >after fees< for 20 straight years like they have.
3%/30% seems rather high, especially if they don't have a long track record to back it up. 1-2%/20% and even 0%/20-30% much more common to hedge fund space. With many HFs down big on the year-- if not folding outright-- just hanging on to assets is the main challenge for many, let alone raising new capital. Perhaps that will put some pressure on fees in general. I imagine many HF investors are further questioning their fees at this point, esp. if their investment has underperformed a 20bp fee index fund. Those HFs that are having good years can use this period to assert that their fees are indeed "worth it".
