Steve Cohen is aiming for more.

His Point72 Asset Management, which attracted $5 billion in outside capital last year in a comeback for the hedge fund investor, is seeking to raise an additional $1 billion between May 1 and September, according to people familiar with the matter.

The firm was one of 2018’s biggest hedge fund launches when Cohen returned to the industry after a two-year ban from managing other people’s money. His prior firm, SAC Capital Advisors, pleaded guilty to securities fraud and paid a $1.8 billion fine. Cohen wasn’t charged with wrongdoing.

A spokeswoman for the firm declined to comment on the latest fund raise.

Point72 had a mediocre start last year, making less than 1 percent for investors. While that performance beat the S&P 500 Index of stocks and the average hedge fund, it wasn’t the blockbuster numbers that many expected, given SAC Capital’s history of averaging annual returns of about 30 percent.

This year has been better. Point72 returned almost 5 percent in the first quarter of 2019. That compares with a 13 percent rise in the S&P and a 3 percent gain for the average hedge fund.
