Biggest Short Squeeze in History: It Wasn't GameStop

If you think GameStop was the biggest short squeeze in history, you're dead wrong. The real king is Volkswagen back in 2008 – and it's not even close. I'm going to break down what happened, why it matters, and how you can avoid getting burned in the next one.

What Is a Short Squeeze?

A short squeeze happens when a heavily shorted stock suddenly rises in price, forcing short sellers to buy back shares to cover their positions. That buying pressure pushes the price even higher, creating a feedback loop. If you haven't witnessed one, it's like watching a freight train accelerate in reverse – violent, fast, and often destructive.

To understand the scale, you need to know the mechanics. When a trader shorts a stock, they borrow shares and sell them, betting the price will fall. If the price rises instead, they face margin calls and must buy shares back. If many shorts are forced to close at once, the stock can explode upward. That's the simple version, but the real monster squeezes involve hidden ownership, complex options, and desperate short sellers.

The Biggest Short Squeeze in History: Volkswagen (2008)

Let's travel back to October 2008. The global financial crisis was raging, markets were in freefall, and the last thing anyone expected was a German carmaker becoming the world's most valuable company. But that's exactly what happened with Volkswagen.

The Setup: Porsche's Sneaky Move

Porsche had been quietly accumulating Volkswagen shares for years. By late October 2008, it revealed that it held roughly 42.6% of VW's ordinary shares plus about 31.5% in cash-settled options. That meant Porsche effectively controlled around 74% of the company. Another 20% was held by the state of Lower Saxony, leaving only about 6% of the free float available to traders.

Here's the catch: hedge funds had massive short positions in VW, betting the stock would crash in the financial meltdown. They didn't realize they were about to be trapped.

The Explosion: What Happened

On the evening of October 26, Porsche announced its holdings. The next morning, short sellers woke up to a nightmare. With only a tiny pool of tradable shares available, they rushed to cover their shorts. The stock price skyrocketed from around €210 to over €1,000 intraday – a rise of more than 500% in just two days. At its peak, Volkswagen's market capitalization reached about €300 billion, briefly making it the most valuable company on Earth.

According to Reuters, short sellers lost an estimated $30 billion in the squeeze. Some hedge funds, like the infamous Greenlight Capital, took huge hits. It was a bloodbath.

Why It's the Biggest

When people talk about the biggest short squeeze, they usually measure by percentage gain or market cap added. GameStop gained about 1,700% at its peak, but the total market cap increase was 'only' around $30 billion. Volkswagen's market cap ballooned by roughly €300 billion – that's 10 times larger. In absolute dollar terms, it dwarfs anything since.

GameStop: The Retail Wildfire

GameStop in early 2021 was a different beast. Reddit's WallStreetBets forum rallied retail investors to buy the stock and call options, squeezing hedge funds that had bet against it. The price went from around $17 to an intraday high of $483 in January 2021. Melvin Capital, a major short seller, needed a bailout from other firms.

But here's the thing: GameStop's float was tiny and short interest was over 100% of it, making the percentage squeeze extreme. Yet the total short interest was around $14 billion, and the market cap peak was roughly $34 billion. Compare that to Volkswagen's €300 billion market cap swing and the overall money involved, and VW wins hands down.

Volkswagen vs. GameStop: Which Was Bigger?

As you can see, GameStop wins on percentage gain and short interest ratio, but Volkswagen dominates in absolute dollar impact. When someone asks 'what is the biggest short squeeze in history?' the answer depends on your metric. But by market cap destruction and total short losses, Volkswagen is the undisputed champ.

How Short Squeezes Actually Work

Let's walk through the mechanics step by step:

Step 1: A stock has high short interest. Many traders borrow and sell shares, expecting the price to fall.

Step 2: Unexpected good news hits. The price starts to rise, or at least doesn't fall as expected.

Step 3: Short sellers get margin calls. Brokers demand more cash or require them to close positions.

Step 4: Forced buying creates a feedback loop. Each buy pushes the price up, triggering more margin calls.

Step 5: The squeeze ends when shorts have been flushed out or buying weakens. It can burn out just as fast as it started.

In Volkswagen's case, the 'unexpected news' was Porsche's announcement. In GameStop's case, it was a coordinated retail campaign. The catalysts differ, but the underlying panic is identical.

How to Spot a Potential Short Squeeze Early

If you want to catch the next big one, look for these red flags:

• High short interest ratio: Netflix or Yahoo Finance show short interest as a percentage of float. Anything above 20% is dangerous; above 40% is a powder keg.
• Days to cover: This metric tells you how many trading days it would take short sellers to cover their positions based on average volume. More than 10 days is risky.
• Low float: If only a few shares are available for trading, a small amount of buying can cause a big move.
• Positive catalysts: Product launches, earnings beats, or activist investors can spark a rally.

But here's my non-consensus take: most retail investors overlook the 'hidden' short interest. In the VW case, the market didn't see the true short exposure because some were hidden in cash-settled options. Always check the options chain and note announcements from major shareholders. That's where the real bombs are.

The Hidden Risks for Retail Investors

You might think short squeezes are easy money – just buy heavily shorted stocks and ride the wave. That's a terrible idea for three reasons:

First, timing is impossible. You never know when the short squeeze will start or end. GameStop crashed from $483 to under $40 within six months, turning many late buyers into bag holders.

Second, short squeezes are man-made black swans. They depend on concentrated positions and hidden information. As a retail investor, you're almost always the last to know. By the time the squeeze is public news, the biggest gains are already gone.

Third, financial instruments like leveraged ETFs can amplify your loss. In the VW squeeze, many retail options traders got wiped out because they bought calls at the peak. The volatility was so extreme that even options with the right direction expired worthless due to time decay.

I remember talking to a guy who bought GameStop at $350 in February 2021. He was so sure it would hit $1,000. Within a few weeks, he was forced to sell at $90 after a margin call. He lost over 70% of his savings. It's not a game.

Lessons From Past Squeezes

Studying these historical events taught me a few things that go beyond the basic narrative:

1. The 'short interest' number on websites is often outdated or incomplete. Always cross-reference with recent data from exchanges and use tools like S3 Partners or IHS Markit. In the VW case, the official short interest was lower than the actual exposure because of options.

2. Watch the 'float' more than the 'total shares outstanding'. In GameStop, the float was shrinking due to buying, but many people ignored the change. A shrinking float plus high short interest is a ticking bomb.

3. Never confuse a squeeze with a bull thesis. A short squeeze is a temporary, self-reversing event. Once the shorts cover, the upward pressure disappears. If the stock doesn't have solid fundamentals, it will eventually fall back down.

4. Institutional investors also get caught. The 2008 VW squeeze crushed many sophisticated hedge funds. You are not immune just because you have a Bloomberg terminal.

These are the hard truths I've gathered from watching two of the biggest squeezes in my lifetime.
