Shares of CAR (the company formerly known as Avis Budget Group) just suffered their steepest single-day decline in nearly two decades, as the most aggressive short squeeze since the GameStop mania of 2021 finally unwound. The stock, which had been propelled to dizzying heights by a wave of retail traders betting against bearish investors, saw those gains evaporate in a brutal reversal that left many wondering if the squeeze had truly ended.

The Unraveling of a Record Squeeze

The crash, which marked CAR's worst day since 2006, sent shockwaves through the trading community. Just weeks ago, the stock was the poster child for what one analyst called the "most structurally violent short squeeze since GameStop," as a perfect storm of limited float, high short interest, and coordinated retail buying forced bearish funds to cover their positions at any cost.

That dynamic, however, proved unsustainable. As the price climbed higher, the incentive for short sellers to capitulate diminished, and the momentum that had fueled the rally began to stall. When the buying pressure finally eased, the stock reversed course with a vengeance, wiping out a significant portion of the gains in a single session.

What Drove the Initial Surge?

The squeeze began after a series of positive earnings reports and a surprising uptick in rental demand, which caught many short sellers off guard. Retail traders, organized on social media platforms, piled into the stock, creating a feedback loop that pushed the price to levels far beyond what fundamentals justified.

  • High short interest as a percentage of float left bears vulnerable to a rapid price increase.
  • Limited share availability made it difficult for short sellers to cover without driving prices even higher.
  • Momentum trading and FOMO (fear of missing out) attracted more buyers, amplifying the move.

At its peak, the stock had gained hundreds of percent in a matter of weeks, drawing comparisons to the infamous GameStop squeeze of early 2021. But unlike that episode, which saw a slow bleed over months, CAR's unwind was swift and brutal.

Why the Squeeze Collapsed

Several factors converged to end the squeeze. First, as the price rose, more short sellers chose to sit tight rather than cover, betting that the rally would eventually falter. This reduced the buying pressure that had been driving the stock higher. Second, some early retail investors began to take profits, creating selling pressure that the market had not seen during the ascent.

The final blow came when the stock's momentum indicators turned negative, triggering a cascade of stop-loss orders and automated selling. Within hours, the stock had given back a substantial chunk of its gains, and by the close, it had recorded its worst daily performance in 20 years.

"The structural dynamics that made this squeeze so violent were also what made it so fragile," noted one market strategist. "Once the buying pressure stopped, there was nothing to hold the price up."

Comparison to GameStop

While the GameStop squeeze of 2021 was driven by a similar mix of high short interest and retail coordination, there are key differences. GameStop's squeeze unfolded over several weeks, with multiple waves of buying and selling. CAR's move, by contrast, was more compressed, with the rally and the crash occurring in a much shorter timeframe.

Additionally, the market environment in 2026 is different, with higher interest rates and a more cautious investor base. This made it harder for the squeeze to sustain itself, as fewer new buyers were willing to chase the stock at elevated valuations.

What Comes Next for CAR?

As the dust settles, investors are left to assess CAR's fundamentals, which have not changed dramatically over the past few weeks. The company still operates a solid rental car business, but its stock price had become detached from its earnings power. Going forward, the stock is likely to trade more in line with its intrinsic value, which could mean further downside if the market remains skeptical.

For short sellers, the worst may be over, but the experience serves as a reminder of the risks involved in betting against a heavily-shorted stock. For retail traders, the episode is a cautionary tale about the dangers of chasing momentum without a clear exit strategy.

Key Takeaways

  • CAR's stock experienced its worst single-day drop since 2006 as a massive short squeeze unwound.
  • The squeeze was driven by high short interest, limited float, and coordinated retail buying.
  • The collapse was triggered by profit-taking, reduced short covering, and negative momentum.
  • Unlike GameStop, CAR's squeeze was shorter and more volatile, reflecting a different market environment.
  • Investors should focus on fundamentals rather than speculative momentum when evaluating stocks.

The episode highlights the unpredictable nature of heavily-shorted stocks and the dangers of speculative trading. While the squeeze may be over, its lessons will linger for traders on both sides of the trade.
