How a short squeeze works
A squeeze has nothing to do with the value of the business and everything to do with who is forced to act.
Understand why a worthless company can triple in a week.
How a short squeeze works works, in one picture
The same argument as the text, as a chain. Each step is what makes the next one possible.
The loop that feeds itself
None of this is a judgement about the company. It is a margin clerk executing a rule, and it stops the moment the forced buying runs out.

Shorting means you owe shares you do not have
A short seller borrows shares, sells them, and plans to buy them back cheaper. The key word is back: they must eventually buy. They have a standing obligation to become a buyer.

Losses on a short are unlimited
A share you own can only fall to zero. A share you have shorted can rise without limit, so your loss is uncapped. This asymmetry is what makes shorts fragile, and everyone in the market knows it.

Rising prices force them to buy
As the price rises, the broker demands more collateral. Shorts who cannot post it must close their position, which means buying. That buying pushes the price higher, which forces more shorts to buy, which pushes it higher still.
The buying is not a judgement about the company. It is a margin clerk executing a rule.

And then it stops, all at once
Once the forced buying is exhausted, the mechanical bid disappears. The price collapses back towards whatever the business is actually worth, which was never what the squeeze was about.
You can explain why the price move ends abruptly rather than fading.
