Short squeeze
📈 MarketA heavily shorted stock rises sharply, forcing short sellers to buy back and pushing it higher still.
Typical size
20-200%, entirely unpredictable
Timeframe
Days to weeks, then usually a full retrace
Evidence
2 logged events
Why it moves the price
Short covering is forced buying. When float is small and short interest is large, that buying overwhelms available supply and price becomes reflexive rather than fundamental.
What separates a good call from a naive one
Direction is up but timing is unknowable and reversals are brutal. Squeezes end when the forced buying is exhausted, and the stock typically returns to where it started. High short interest alone predicts nothing without a catalyst.
