Investors betting against retail trader favorites GameStop Corp. and AMC Entertainment Holdings Inc. were dealt a serious blow on Wednesday to the tune of about $673 million, according to data from financial analytics firm S3 Partners.
GameStop and AMC, two wildly popular meme stocks among members of Reddit’s WallStreetBets forum, soared more than 16% and 19% respectively as speculative assets picked up steam. Those gains pushed mark-to-market losses for short-sellers to roughly $8.1 billion for the year, according to S3 Partners data.
