The quants ruled the world once again in Institutional Investor’s 17th-annual Hedge Fund 100 ranking of global hedge fund firms by assets. Of the top five firms, four are quantitatively managed, with one of them — Greenwich, Connecticut-based AQR Capital Management — growing its assets by a stunning $20 billion, or 29 percent. Renaissance Technologies grew its assets by 35.7 percent, to $57 billion, bumping it up to No. 3 in the rankings this year, while Two Sigma’s assets increased by 33.4 percent, to $52 billion.

Last year’s strong performance gains undoubtedly played a role in bumping up the total capital managed by the top 100 hedge fund firms. This group controlled $1.73 trillion in hedge fund assets at the start of 2018, a nearly 5 percent gain over the previous year’s total.
