The Renaissance Technologies Medallion Fund has produced some of the greatest returns in the history of the markets. They have the best returns for consistency, percentage of returns and did this while trading billions in capital.
They have been so successful that they had to close down this fund to new outside investors. It now only trades current and former employees and partners capital. To keep the fund size stable they now distribute annual gains to prevent further compounded growth. $10 billion seemed to be the liquidity cap for their systems ability to trade without moving their markets, because when trade size becomes too big a fund can become the market.
From 1988 to 2020 the Renaissance Technologies Medallion Fund has grown from $20 million to over $10 billion of assets under management.
