What is a meme stock?

A meme stock is a stock whose price action is dominated by online attention — viral posts, in-jokes, coordinated retail buying, and social-media momentum — rather than by traditional valuation. The term comes from internet "memes," the shared images and phrases that travel through communities at speed. Meme stocks travel the same way.

01 — SectionWhat makes a stock a meme

• A passionate retail community, usually on Reddit, X, Discord, or TikTok.
• A simple, shareable narrative — "the most-shorted stock," "the AI play," "the one Wall Street hates."
• High short interest or a low float, so small inflows move the price a lot.
• Price action that ignores or directly contradicts the fundamentals.
• Inside language: rocket emojis, diamond hands, "to the moon," cult-of-personality CEOs.

02 — SectionThe canonical examples

GameStop and AMC, in 2021, defined the modern meme stock — both ran 10x or more on retail buying and a textbook short squeeze. Bed Bath & Beyond, Hertz (out of bankruptcy, of all things), Blackberry, Nokia, Tilray, Beyond Meat, Trump Media, and a long tail of pre-revenue EV and biotech names have all had meme-stock episodes since.

03 — SectionAnatomy of a meme rally

Meme rallies have a recognizable shape. A latent community accumulates quietly. A catalyst — a viral thread, a celebrity tweet, an earnings surprise — drags attention in. Mention volume explodes, call-option volume explodes, the price gaps higher, and the move feeds on itself through forced short covering and dealer hedging. Then attention peaks, the marginal buyer disappears, and the stock retraces — often violently — over the following weeks. The retracement rarely makes the news; the rally always does.

Meme stocks are markets at their most honest: the price is the conversation.

04 — SectionThe risks

Meme stocks are not casino chips, but they trade like them. Most of the spectacular returns accrue to early entrants and disciplined sellers; the typical late buyer underperforms badly. Bid-ask spreads widen, options premiums become punitive, and exit liquidity can disappear in a single session. Position sizing matters more here than anywhere else in the market.

05 — SectionHow to spot the next one

The earliest tell is attention, which is exactly what this site tracks. A small-cap name that suddenly shows up on the Buzz leaderboard with a triple-digit jump in 24-hour mentions, high short interest, and an active retail thread is the prototypical setup. Most won't go anywhere. The ones that do, do so within days.
