Meme stocks are a documented market phenomenon — social-media-coordinated retail buying producing price moves disconnected from a company's actual underlying financial performance.
The Documented History
The phenomenon exploded into mainstream view in January 2021 with GameStop: retail investors on Reddit's r/WallStreetBets identified that hedge funds had shorted the stock at over 100% of available shares, and coordinated buying triggered a short squeeze that sent the price from under $20 to over $480 within weeks. AMC followed with its own squeeze in May 2021, peaking above $72 per share. Both moves were driven by coordinated retail demand and high short interest — not by underlying earnings or revenue improvements at either company.
A high short-interest percentage is the specific mechanical fuel behind a short squeeze — heavily shorted stocks force short sellers to buy back shares to cover losses as price rises, adding additional buying pressure on top of retail demand, which is exactly what made the 2021 moves so extreme.
