Hedge fund managers fear the painful losses they suffered in the meme stock trading frenzy of January 2021 will be repeated if US regulators press ahead with reforms to securities lending, one of the most opaque practices in financial markets.
Melvin Capital, Light Street and White Square all lost heavily when their bets against meme stocks, such as the struggling video game retailer GameStop, were pulverised by retail investors who swap trading ideas on bulletin boards such as Reddit’s r/wallstreetbets.
But the extreme volatility unleashed in the meme stock battle alarmed the Securities and Exchange Commission, the US financial markets regulator which is determined to prevent a repeat of the debacle.
