Meme Stock

A stock that experiences dramatic price movements driven primarily by social media hype and retail trader enthusiasm rather than fundamental valuation. GameStop and AMC Entertainment became the poster children of the meme stock phenomenon in January 2021, when coordinated buying on Reddit's WallStreetBets forum triggered massive short squeezes. Meme stocks have since become a recognized market force, blending internet culture, populist anti-Wall Street sentiment, and speculative fervor into a new category of trading.
