AMC Entertainment Stock Soars Nearly 80% as Meme-Stock Craze Returns

GME rallied on the first posting in some three years from "Roaring Kitty," a prominent backer of the stock on Reddit's WallStreetBets chat group.

Roaring Kitty, who has reportedly been identified as Keith Gill, helped launch the meme-stock craze in 2020-21 when he and others talked up a number of stocks on WallStreetBets. Others soon joined in, sending stocks like AMC and GME to massive heights.

Although the stocks later fell back hard, they've since had occasional rallies like Monday's.

But even after Monday's run-up, AMC is still down 99.3% from the $726.20 intraday peak that it hit in June 2021.
