He is often called the ‘quant king’ due to his commendable knowledge of mathematics. He has had a successful career in mathematics and has taught at famous universities, including Harvard.

Despite his successful mathematics career, Jim Simons had a strong passion for finance, and he chose to pursue his interest through day trading. After some time in day trading, Jim founded Renaissance Technologies in 1982. He served as the chair and CEO of the company from 1982 to 2010.

Jim Simons Day Trading Journey: How He Started Renaissance Technologies

In 1978, Jim quit his academic career at Stony Brook University and founded his first hedge fund firm, Monemetrics. He didn’t know he could apply mathematical models in the hedge fund forecast at that time, but he tried. He used technical and fundamental approaches, which had moderate success due to the stock market's emotional swings.

Jim was persistent with using varying mathematical models in his newly founded firm and eventually found that he could forecast the returns using statistical and mathematical models.

We use historical data to find anomalous patterns which we wouldn’t expect to happen randomly. We trade it if it’s liquid and amenable,” he said.

The Birth of a Hedge Fund

Four years later (in 1982), Jim started Renaissance Technologies, a prestigious firm that manages more than $55 billion in investments. He involved other experts from mathematics, data analysis, programming, and statistics fields to help come up with more strategies and models to be used in trading.

The team developed advanced mathematical formulas, which they used to make more accurate investment predictions and increase the company's success.

Jim Simons not only owns Renaissance Tech but also owns the Medallion Fund. Jim founded medallion in 1988, and Renaissance Technologies managed the company. It has grown to be one of the most successful hedge funds in the world, with impressive returns.

Jim recently stepped down as the CEO of Renaissance Technologies, but his interest in quantitative investing hasn’t gone down yet. He still makes essential decisions and supports active day traders through his ideas.
