Melvin Capital, the hedge fund that was wrongfooted by retail traders who drove up shares in GameStop and other companies it had bet against, lost 53 per cent in January, according to people familiar with the firm’s results.

The New York-based hedge fund sustained a $4.5bn fall in its assets from the end of last year to $8bn, even after a $2.75bn cash injection from Steve Cohen’s Point72 Asset Management and Ken Griffin’s Citadel.

Melvin became the target of retail traders who co-ordinated to drive up the share price of GameStop on online message boards such as Reddit, after the firm disclosed its bet against the company in regulatory filings. The Securities and Exchange Commission announced on Friday it was looking into what happened when Redditors drove shares dramatically higher, but lawyers doubt it will lead to prosecutions. In order to prosecute traders, regulators would need to find evidence of deception to prove market manipulation, say lawyers.

The SEC is not only looking into the traders who bought stock last week however: it is also probing the brokerages that enabled the trades, before placing temporary curbs on them, triggering sudden share price drops. (FT, Bloomberg)
