Yes, that takes a few seconds: "Renaissance's flagship Medallion fund, which is run mostly for fund employees, is famous for the best track record on Wall Street, returning more than 66 percent annualized before fees and 39 percent after fees over a 30-year span from 1988 to 2018."

Now, can anyone find the performance for AQR's flagship fund?
The fund doesn't compound returns - ie, it is constantly returning money to its investors. So without the AUM, the returns while strong, don't tell you a lot. The annualized figure doesn't tell you much because in the first few years, they could have been thousands of percent on tiny notionals (like 5-10 million) whereas it's a 6Bn fund now, producing more modest returns.
