When the Porsche vs. Volkswagen dust finally settled, hedge funds had lost an estimated $30 billion — one of the largest collective losses from a single stock event in history.
The reason was simple: margin.
As Volkswagen’s share price surged, short sellers were hit with escalating margin calls.
When they couldn’t deliver shares to meet those requirements, brokers stepped in and forced buy-backs at whatever price the market was printing — no negotiation, no delay.
Each buy-back pushed the stock even higher, creating a self-reinforcing feedback loop that made the squeeze more severe.
The break didn’t come until Porsche released roughly 5% of its shares back into the market, injecting enough liquidity for the price to fall from its historic peak.
But this was all unfolding during the height of the 2008 financial crisis.
Credit markets froze, banks pulled back, and Porsche — which had relied heavily on leverage to build its position — suddenly faced a liquidity crunch of its own.
Within a few years, after complex restructuring, Porsche’s automotive business was folded into Volkswagen — an extraordinary reversal for a company that had come within inches of taking VW over.
A once-in-a-century short squeeze… with an ending no one expected.
