What is Short Squeeze?

A short squeeze happens when a heavily shorted stock suddenly rises in price, forcing short sellers to buy shares to cover their losses — which drives the price even higher, forcing more short sellers to cover, creating a feedback loop. It's a beautiful, chaotic, self-reinforcing spiral that ends badly for at least half the people involved.

Short sellers borrow shares and sell them, betting the price will fall. If instead the price rises sharply, their losses mount and brokers issue margin calls. To close their position, short sellers must buy the stock — adding fuel to the fire. The more shorts there are, the bigger the potential squeeze. GameStop 2021 is the textbook example.

Key indicators: high short interest (20%+ of float shorted), high short interest ratio (days to cover), and a catalyst that could drive the stock up. No method is reliable — if it were, everyone would use it and the squeeze would already be priced in. WallStreetBets finds them by vibes and spite.

In January 2021, retail investors on WallStreetBets coordinated to buy GameStop (GME) shares, which had been heavily shorted by hedge funds. GME went from ~$5 to ~$483 in weeks. Hedge fund Melvin Capital lost billions. The event became a cultural moment about retail vs. Wall Street — and then everyone got poor again.

Buying a stock you believe in is perfectly legal. Coordinating a campaign to artificially manipulate the price is market manipulation, which is illegal. The line is blurry in the age of Reddit — regulators are still figuring out where organic enthusiasm ends and illegal coordination begins. Proceed accordingly.
