was instrumental in evolving trading to shorter-dated, pure systems driven decision-making. The hedge fund was named Medallion in honor of the math awards that Simons and Ax had won.
Renaissance's flagship Medallion fund, which is run mostly for fund employees, is famed 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. Renaissance offers two portfolios to outside investors—Renaissance Institutional Equities Fund (RIEF) and Renaissance Institutional Diversified Alpha (RIDA).[
Because of the success of Renaissance in general and Medallion in particular, Simons has been described as the "best money manager on earth".
Simons ran Renaissance until his retirement in late 2009.] He continued to play a role at the firm as non-executive chairman, which he stepped down from in 2021, and remains invested in its funds, particularly the Medallion fund. The company is now run by Peter Brown (after Robert Mercer

has employed mathematical models to analyze and execute trades, many of them automated. The firm uses computer-based models to predict price changes in easily traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions. Some also attribute the firm's performance to employing financial signal processing techniques such as pattern recognition. The book '' The Quants'' describes the hiring of speech recognition experts, many from IBM, including the current leaders of the firm.

Monemetrics
In 1978, Simons left academia and started a hedge fund management firm called Monemetrics in a Long Island strip mall. The firm primarily traded currencies at the start. It did not occur to Simons at first to apply mathematics to his business, but he gradually realized that it should be possible to make mathematical models of the data he was collecting.
Monemetrics’ name was changed to Renaissance Technologies in 1982. Simons started recruiting some of the mathematicians and data-modeling types from his days at the Institute for Defense Analysis (IDA) and Stony Brook University. His first recruit was Leonard Baum, a cryptanalyst

. When Baum abandoned the idea of trading with mathematical models and took to fundamental trading, Simons brought in algebraist James Ax from Cornell University. Ax expanded Baum's models for trading currencies to cover any commodity future and subsequently Simons set up Ax with his own trading account, Axcom Ltd., which eventually gave birth to the profitable fund — Medallion. During the 1980s, Ax and his researchers improved on Baum's models and used them to explore correlations from which they could profit.
Medallion Fund
In 1988, Renaissance established its most profitable fund, the Medallion fund (previously the Limroy Colombian fund), which used an expanded form of Leonard Baum's mathematical models

, started Medallion, which they named after their awards in mathematics. The initial success of the company's models led Simons to base the fund's trades entirely on the models.
By April 1989, however, peak-to-trough losses had mounted to about 30%. Ax claimed to have accounted for such a decline in his models and insisted on continuing to trade. Simons wanted to pause and reevaluate; Simons, as majority owner, prevailed, and Ax departed. Simons then asked Berkeley professor Elwyn Berlekamp
Elwyn Ralph Berlekamp (September 6, 1940 – April 9, 2019) was a professor of mathematics and computer science at the University of California, Berkeley.Contributors, ''IEEE Transactions on Information Theory'' 42, #3 (May 1996), p. 1048. DO10. ...
to run Medallion. A consultant for Axcom whom Simons had first met at the IDA, Berlekamp had acquired most of Ax's stake in Axcom and became its CEO. He worked with Sandor Straus, Jim Simons and another consultant, Henry Laufer, to overhaul Medallion's trading system over the course of six months. In 1990, Berlekamp led Medallion to a 55.9% gain, net of fees, and then returned to teaching math at Berkeley after selling out to Simons at six times the price for which he had bought his Axcom interests sixteen months earlier. Straus then took Berlekamp's place, running Medallion's revamped trading system, which returned 39.4% in 1991, 34% in 1992 and 39.1% in 1993, according to Medallion annual reports.[
The Medallion fund is considered to be one of the most successful hedge funds ever. From 1994 through mid-2014, it averaged a 71.8% annual return, before fees.] The fund has been closed to outside investors since 1993 and is available only to current and past employees and their families. The firm bought out the last investor in the Medallion fund in 2005 and the investor community has not seen its returns since then. About 100 of Renaissance's some 275 employees are "qualified purchasers", meaning they generally have at least $5 million in assets to invest. The remaining are "accredited investors", generally worth at least $1 million.[
By 2000, the computer-driven Medallion fund had an average annual return of 34% after fees from its 1988 inception.] Simons ran Renaissance until his retirement in late 2009. Between January 1993 and April 2005, Medallion only had 17 losing months and out of 49 quarters over the same period, Medallion had only three losing quarters. Between 1989-2005 Medallion had only one year showing a loss: 1989.
During 2020 the Medallion fund surged 76%.

regardless of income. By 2012, Renaissance was granted a special exemption by the United States Labor Department allowing employees to invest their retirement money in Medallion arguing that Medallion had consistently outperformed their old 401(k) plan. In 2013, Renaissance's IRA plans had 259 participants whose $86.6 million contribution grew to $153 million that year without fees or annual taxes. Renaissance set up a new 401(k) plan, and in November 2014 the Labor Department allowed that plan to be invested in Medallion as well.
Renaissance Institutional Equities Fund (RIEF)
In 2005, Renaissance Institutional Equities Fund (RIEF) was created. RIEF has historically trailed the firm's better-known Medallion fund, a separate fund that only contains the personal money of the firm's executives. In April 2020, Institutional Investor reported that the disparity between Renaissance's Medallion fund and other funds, including RIEF, was approximately 17-19%. Renaissance also offers two Renaissance Institutional Diversified Alpha (RIDA) to outsiders.[ Simons ran Renaissance until his retirement in late 2009.] Renaissance Institutional Equities Fund had difficulty with the higher volatility environment that persisted throughout the end of the summer of 2007. According to an article in ''Bloomberg'' in August 2007,
RIEF once again struggled in the high volatility environment of 2020. According to an article in ''Bloomberg'' in November 2020,
From December 1st 2020 to February 1st 2021, according to ''Bloomberg'', clients (LPs) had withdrawn $5 billion from the fund.
On 25 September 2008, Renaissance wrote a comment letter to the Securities and Exchange Commission
