Quant fund, long-only 13F filer

Renaissance Technologies

Renaissance Technologies is the quantitative firm mathematician Jim Simons founded in 1982, trading purely on statistical models; its 13F reflects the thousands of machine-selected positions in its institutional funds. It discloses US-listed long equity (and some options) positions each quarter on SEC Form 13F — bonds, cash, private businesses and non-US holdings are not in that filing.
