15 Most Successful Investors of All Time

2. Jim Simons

Net worth: $30.7 billion

As discussed earlier, Jim Simons was the leading investor when it came to quantitative investing. He had adopted the same investment strategy for Renaissance Technologies, the world’s largest quantitative fund. Renaissance Technologies, under this strategy, regularly buys and sells thousands of stocks annually, based on sophisticated computer algorithms. Despite its success, the fund has underperformed as compared to the market in recent times due to the sheer size it has grown to.

According to Yahoo Finance, Renaissance Technologies’ biggest 13F equity position at the end of the third quarter (2023) was Novo Nordisk A/S (NYSE:NVO) in which the fund held 15.31 million shares.
