The squeeze depended on a deadline
Clarence Saunders’s plan turned on a basic feature of short selling. A short seller borrows shares, sells them, and hopes to buy them back later at a lower price. The borrowed shares still have to be returned, so if too few are available, short sellers may be forced to compete for them—pushing the price higher. That rush to buy is a short squeeze.
Saunders tried to create that shortage in Piggly Wiggly stock. By buying up shares, he aimed to leave short sellers with few places to turn when they had to return what they had borrowed. The tighter the supply and the nearer the deadline, the greater the pressure to pay whatever the remaining sellers demanded.
More time changed the leverage
But a squeeze is not just about how many shares a buyer controls. It also depends on when short sellers must act. When the exchange changed the deadline, the sellers gained more time to locate shares. That weakened Saunders’s central advantage: instead of having to scramble immediately, his opponents could search for stock and make arrangements to meet their obligations.
Saunders, meanwhile, had committed enormous sums to buying shares. The strategy left him exposed if the price fell or if the squeeze failed to force short sellers into a frantic buying rush. He had taken on financial obligations in pursuit of a market outcome he could not control by himself; the exchange’s decision changed the timing on which that outcome depended.
A corner can trap its creator
The episode shows why trying to corner a stock is so risky. A buyer may make shares scarce, but cannot guarantee that a deadline will stay fixed or that other market participants will be unable to find stock. Once Saunders’s plan lost its urgency, the positions he had financed became a liability rather than a weapon. He was bankrupt within days—a reminder that a trade designed to make opponents desperate can leave its architect carrying the biggest bill.
