Business Description
Renaissance Technologies LLC ("Renaissance" or the "Firm") is an investment management firm, founded in 1982, that implements quantitative investment strategies on behalf of its clients. It acts as general partner, managing member, and/or investment manager to U.S. and non-U.S. private investment funds (the "Funds") that invest in a variety of securities, futures, and derivatives contracts.
Renaissance is owned by two parent companies: Renaissance Technologies Holdings Corporation (with approximately a 77% stake) and RTC II Holdings LLC (with approximately a 23% stake). Renaissance's clients include the Fund Families and the Kaleidoscope Fund.
Investment Strategy
The Firm employs speculative investment and trading strategies across its Medallion, RIEF, and RIDA Funds. The Medallion Funds aim for asset appreciation through trading in securities, futures, and derivatives. The RIEF Funds trade global equity securities and derivatives listed on U.S. exchanges, targeting long-term risk-adjusted returns exceeding the Standard & Poor's 500 Index, while maintaining a low beta (0.4 or lower) and lower volatility than the Index, with an average leverage of approximately 2.5 to 1. The RIEF Funds’ trading strategy is designed with the objective that the RIEF Funds be no more than $100 net long for each $100 of equity.
The RIDA Funds trade equity securities publicly traded on global exchanges. The RIDA Funds expect most returns over the long term to come as alpha as the Funds are intended to have low correlation to the U.S. and global equity markets. Prospective investors should be aware that these investments are speculative and volatile, involving substantial risk, and are suitable only for investors who can tolerate significant risk.
