Short Squeeze: What Is It and How to Predict a Bitcoin Short Squeeze

Definition

A short squeeze occurs when a sudden market movement forces short sellers to buy back an asset en masse, creating a self-reinforcing dynamic that drives the price higher and higher. This forces short sellers out of the market, typically at a loss. The phenomenon represents one of the most dramatic events in financial markets, where bearish positions are rapidly unwound due to unexpected price movements.

Short squeezes force short sellers to re-enter an asset by buying it back, which drives the price up and pushes more short sellers out of the market. A short squeeze can also occur when there is a supply disruption or excessive demand for an asset because many short sellers must close their positions. Understanding this mechanism is crucial for traders who engage in short selling or trade in highly volatile markets.

One of the most frequently used words in the trading world is "risk." Betting on the performance of an asset involves a certain degree of risk, but with the right knowledge, experienced traders can be successful regardless of market conditions. Short selling is a bet on the decline in value of an asset, where the asset is borrowed and sold to buy it back at a lower price and return it. The remaining amount after interest and fees is the profit. However, when markets move against short positions, the consequences can be severe and rapid.

What Is Short Selling?

Short selling is a common practice that keeps both investors and companies on their toes. It is only worthwhile to hold an investment if you know it can be sold later. When an asset appears overvalued, traders will short sell it. This practice serves as a market correction mechanism, helping to identify overpriced assets and bring their valuations back to realistic levels.

GameStop was recently the most shorted company in the S&P 500, primarily due to the widespread belief that the company would not survive the shift away from retail during the coronavirus era. This sentiment created a massive short position that would later become one of the most famous short squeezes in recent financial history. The case demonstrates how collective market sentiment can create conditions ripe for dramatic price reversals.

Short Selling in Cryptocurrency Markets

This also applies to cryptocurrencies, where short selling has become increasingly sophisticated. The sentiment around privacy tokens is rather gloomy as regulators tighten know-your-customer requirements and ban anonymous transactions. The number of short positions in Monero, arguably the most well-known privacy coin in the blockchain space, has been rising since mid-2020. According to market data, there are currently more than three times as many short as long positions, most of them unsecured.

However, when the market does not follow traders' predictions and the asset instead increases in value, traders rush to buy back to minimize their losses. In most cases, especially with cryptocurrencies, it is much easier to short an asset using a derivative contract. And since some of them have an expiration date, traders are sometimes forced to react quickly. This time pressure can amplify the intensity of a short squeeze, as traders scramble to exit positions before contracts expire or margin calls force liquidation.

What Is a Short Squeeze?

During a sudden market movement, short sellers buy back an asset en masse, creating a self-reinforcing dynamic that drives the price higher and higher. This forces short sellers out of the market, typically at a loss. The mechanics of a short squeeze create a feedback loop where rising prices trigger more buying, which in turn drives prices even higher.

After GameStop stock fell to about 6% of its all-time high, it began to rise in a short squeeze starting in September 2020 and grew tenfold over the next few months. The short squeeze is very powerful and can create extraordinary price movements in short periods. In 2008, a short squeeze caused Volkswagen stock to rise fivefold in just two days, briefly making it the most valuable company in the world. These historical examples demonstrate the explosive potential of short squeezes when multiple factors align.

A short squeeze comes quickly, without warning, and takes no prisoners. With a short interest ratio of 18%, Tesla's 400% rise from late 2019 to early 2020 cost short sellers a total of over $8 billion. However, the downturn in March flushed $50 billion back into their pockets within days. This is a dangerous situation, and it requires both knowledge and experience to handle a short squeeze well. The volatility works both ways, and timing becomes crucial for both short sellers trying to exit and opportunistic traders trying to profit from the squeeze.

Is a Short Squeeze Good or Bad?

Regardless of how confident a trader is that an asset will lose value, a short position can quickly be wiped out by something as simple as a product announcement from the company or other positive news. Even if these price changes are only temporary, they can lead to severe losses and even complete liquidation if not controlled. The asymmetric risk profile of short selling means that losses can theoretically be unlimited, while gains are capped at 100%.

How Does a Short Squeeze Happen?

A short squeeze forces short sellers to buy back the asset, driving the price higher and forcing more short sellers to buy back. A short squeeze can also occur when there is a supply disruption or excess demand for an asset, such as when short sellers must close their positions. The trigger can be fundamental news, technical breakouts, or even coordinated buying by contrarian investors who identify heavily shorted stocks.

Being caught on the wrong side of a short squeeze can be devastating for traders and portfolios. A good way to avoid this is to provide all short positions with hard stops, which can protect your capital from sudden market movements in both directions. Risk management becomes paramount when engaging in short selling, as the potential for rapid losses during a squeeze is substantial.

How to Predict a Short Squeeze

It is virtually impossible to always accurately predict a short squeeze, as market dynamics can change rapidly and unexpectedly. However, by monitoring heavily shorted assets, traders can react quickly when one occurs. In such scenarios, assets can also be traded like momentum assets, but due to the highly volatile environment, it is essential to start small and manage position sizes carefully.

Short Interest Percentage

The first metric to consider is the short interest percentage of an asset, which indicates the number of short sales relative to the total number of issued assets. It is expressed as a percentage, and the higher its value, the more short sellers will compete during a squeeze. A sudden increase or decrease in the short interest percentage can be very revealing and provide early warning signals.

Even a 10% increase means that one-tenth of the market has shorted, which is a reasonable signal for further investigation. Bullish investors view high short interest as an opportunity to profit from a sudden trend reversal. During a squeeze, short sellers reduce supply by struggling to buy back their borrowed assets. Since short squeezes tend to occur more frequently in lower market cap securities, a supply shortage can quickly arise in such situations.

How to Calculate the Short Interest Ratio

The short interest ratio (also known as "days to cover") can track market sentiment by observing when the value is outside its normal range. It is calculated by dividing the number of short sales made by the average daily volume of the asset in question. When this metric is in the lower range, it may be a sign that an asset is overvalued or that short sellers are pulling back due to price stability.

An increase to the upper range generally means that investors are bearishly positioned. Very high values, on the other hand, may indicate an imminent short squeeze. This can prompt speculative investors to buy even more of the asset, driving the price even higher. The ratio provides insight into how long it would take for all short sellers to cover their positions at normal trading volumes.

Is Short Squeeze Profitable?

Contrarian investors, who trade against general market sentiment, regularly buy assets with high short interest to profit from potential short squeezes. While taking profits during a squeeze is very tempting, it also carries risks. Perhaps the short sellers reasonably assessed the value of the asset, and the sudden price increase is only short-lived. Distinguishing between a temporary squeeze and a fundamental revaluation requires careful analysis.

Active traders regularly monitor heavily shorted assets to enter exactly when the squeeze begins. While there are countless examples of assets that experienced a short squeeze after high short interest, there are also assets with high short interest that continue to lose value. Not every heavily shorted stock will experience a squeeze, and some may be shorted for legitimate fundamental reasons.

High short interest does not necessarily lead to a short squeeze but is usually just a sign that a large part of the market believes the asset is overvalued. It is probably not a good idea to invest in such securities based solely on short interest, especially since a large part of the market expects them to lose value. However, when combined with signals from other indicators, trading assets with high short interest can be extremely profitable.

For example, consider an asset with a short interest of 20% and a short interest ratio ("days to cover") of five. This means that short sellers need five days to buy back all their sold securities. In a scenario where a sudden product launch or news item drives up the price of the asset, many of the short sellers would have to close their positions, with those most heavily shorted being hit the hardest. The combination of high short interest and low days to cover creates ideal conditions for an explosive short squeeze.

Short Squeeze Versus Long Squeeze

Similarly, in a "long squeeze," the value of an asset suddenly drops, leading to greater selling pressure and pushing long positions out of the market to protect their investments. While the long squeeze is far less popular than the short squeeze, it is much more common in smaller, less liquid markets where determined and panicked investors create higher volatility.

This is because while a short squeeze forces short sellers to liquidate, a long squeeze must trigger sufficient panic for long position holders to start selling. There is no fundamental basis for sales, and they can be both very short and very long, depending on various conditions. When the price falls too low, short-term investors typically drive prices back up after receiving the "oversold" signal. Long squeezes often resolve more quickly than short squeezes due to the different psychological dynamics involved.

When it comes to liquidity, it is important to keep an eye on technical metrics such as supply and demand. Aggressively growing stocks are generally more vulnerable to long squeezes, especially when volume is very high. The best way to deal with such bottlenecks is to focus on investing in value assets. Undervalued assets typically recover unless there was a fundamental reason for the sell-off.

Using Automated Trading Systems to Trade a Short Squeeze

With the advent of automated trading systems, bots can quickly enter low-liquidity markets and profitably exploit both long and short squeezes. Large players can easily manipulate an asset with limited market capitalization and trigger a cascade effect that drives the price in both directions. Algorithmic trading has added a new dimension to squeeze dynamics, as automated systems can react faster than human traders and amplify price movements.

Short Squeezes in the Cryptocurrency Market

In a notable historical instance, Bitcoin surprised the market with a jump from under $9,500 to a 4-month high of nearly $10,400 in just one day. This triggered the highest number of liquidations on a major derivatives exchange since October 2019 – worth a staggering $133 million. Bitcoin shorts worth over $430 million were liquidated across all platforms in less than 24 hours, with most occurring in the hour after Bitcoin crossed the $10,000 mark. This event demonstrated the extreme volatility and rapid liquidation cascades that can occur in cryptocurrency markets.

How Does a Short Squeeze Occur in the Cryptocurrency Market?

Short squeezes occur when traders force a demand surge during temporary supply shortages. This can significantly increase volatility in low-liquidity markets, and the greater the short interest, the easier it is to push short sellers out of the market. The 24/7 nature of cryptocurrency markets and the prevalence of high-leverage trading create conditions where short squeezes can develop and resolve more rapidly than in traditional markets.

That said, short squeezes can occur in any financial market, including more liquid large-cap investments. While Bitcoin does not have the best liquidity, especially compared to traditional stocks and shares, Bitcoin's recent rise to around $40,000 has increased Bitcoin's market capitalization to over $1 trillion. This increased market size has somewhat reduced the frequency of extreme short squeezes, though they still occur regularly.

How Often Does a Short Squeeze Occur?

Short squeezes occur frequently in cryptocurrency markets, especially in Bitcoin markets. Some Bitcoin derivatives markets use highly leveraged positions that can be liquidated even with relatively small price movements. In markets as volatile as cryptocurrencies, liquidation is best avoided by controlling the amount of leverage used and applying better risk management strategies. The combination of high leverage, 24/7 trading, and rapid price movements makes cryptocurrency markets particularly susceptible to short squeeze events.

Traders in cryptocurrency markets should be especially vigilant about monitoring short interest levels and maintaining appropriate stop-loss orders. The speed at which a short squeeze can develop in crypto markets often exceeds that of traditional financial markets, leaving little time for manual intervention. Understanding these dynamics and preparing for potential squeezes is essential for anyone engaging in short selling or leveraged trading in the cryptocurrency space.
