How to Spot a Potential Short Squeeze in the Options Market

A short squeeze sure sounds like a cute thing, like a quick hug. But hang on before you try to short-squeeze anyone—in the options market, it’s anything but a nice gesture. In a short squeeze, a stock that’s been heavily shorted starts going up unexpectedly, and traders who bet against it scramble to buy it back, which pushes the prices even higher.

It’s a chain reaction that triggers some of the biggest and fastest price jumps in the market. Did you see The Big Short? The film explains the 2008 housing financial crisis and what caused it. A group of investors shorted the market, believing that the housing bubble would burst.

The film’s synopsis explains it like this: “Wall Street guru Michael Burry realizes that a number of subprime home loans are in danger of defaulting. Burry bets against the housing market by throwing more than $1 billion of his investors’ money into credit default swaps. His actions attract the attention of a banker, a hedge-fund specialist, and other greedy opportunists. Together, these men make a fortune by taking full advantage of the impending economic collapse in America.”

The result of a short squeeze? A rapid and super chaotic spike that catches almost everyone totally off guard.

For options traders, seeing the early signs of a potential short squeeze isn’t just useful—it can also give them access to opportunities. We are going to go over the clues that could help you catch wind of a possible squeeze before it hits head-on. With the right info, you’ll be ready and able to ride the wave duck dive to avoid it—and stay a step ahead of the market!

What Is a Short Squeeze?

A short squeeze happens when a stock that’s been heavily bet against (or “shorted”) by traders suddenly goes up out of nowhere, catching the short sellers asleep at the wheel. When someone shorts a stock, they borrow shares to sell at the current price and then hope to buy them back later at a lower price. But when the stock’s price goes up instead, traders feel the pressure to buy it back faster than they would have to prevent more losses. A buying frenzy like this pushes the price up even higher, and that creates a chain reaction that can send the stock price through the roof.

Short squeezes can be kicked off by anything that gets buyers interested—good news, sudden popularity on social media, or investors realizing how heavily the stock is shorted. And when short sellers rush to close their positions, the price keeps climbing, making the “squeeze” even more intense.

Why Short Squeezes Matter for Options Traders

In options trading, a short squeeze isn’t just an interesting event; it can and does cause some serious market action. When a short squeeze hits, stock prices swing wildly, and the options market heats up. Call options (which give the right to buy a stock at a specific price) usually become really popular as traders get in on the rising price trend. The demand drives up the price, or “premium,” of the options, and that gives options traders a chance for high returns and rewards.

But—and this is a big “but”—short squeezes bring about huge volatility. Prices will go up fast, and they can drop just as quickly once the excitement dies down. Sure, the premiums on options are super tempting, but the risks are just as high. Options traders who are able to see the early signs of a squeeze might find novel opportunities, but it’s a market that calls for quick thinking and perfect timing.

Recent Short Squeezes in the Market

Some of the biggest recent short squeezes have played out like stock market soap operas, and GameStop and AMC were part of the drama.

• GameStop (GME): In 2021, GameStop became the poster child for short squeezes. Big institutions had heavily shorted the stock, assuming the struggling video game retailer was on its way down. But a big influx of retail investors, fueled by Reddit’s WallStreetBets community, started buying. This sudden demand caused the stock price to skyrocket from under $20 to nearly $500. For options traders, it was an insane ride—the price of call options on GameStop soared, yielding massive profits for those who got in early or had already positioned themselves with call options.
• AMC Entertainment (AMC): Right on the heels of GameStop’s squeeze, AMC saw its own explosive rally. Another heavily shorted stock, AMC’s price jumped as retail investors swarmed in. The short sellers, once again, had to buy back shares to cover their positions, which drove the price even higher. Options on AMC became hot ticket items, with premiums rising fast. For those who timed it right, AMC’s short squeeze was an opportunity to see big returns, although the high volatility did make it a super risky play.

Key Indicators of a Potential Short Squeeze

Identifying a potential short squeeze can be a really valuable strategy for traders who are looking to capitalize on rapid stock price movements, and being able to recognize the telltale signs of an impending short squeeze can help traders make the smartest decisions. Below, we’ll go over the biggest indicators to watch out for!

High Short Interest Ratio

The short-interest ratio measures the number of shares sold short but are not yet covered, which are divided by the stock’s average daily trading volume. A high ratio shows that a large portion of the stock’s shares are being shorted. A short interest ratio above 20% suggests that a lot of investors are betting against the stock, and if the stock’s price starts to go up, the short sellers will rush to cover their positions, and that leads to a short squeeze.

The following are some great sources to find short interest ratio data:

• FINRA: The Financial Industry Regulatory Authority publishes short interest data for all exchange-listed and over-the-counter (OTC) equity securities.
• Nasdaq: Has short interest reports for Nasdaq-listed stocks.
• MarketWatch: Provides tools to screen for stocks with high short interest.
• Investopedia: Features extensive articles that explain how to find a stock’s number of shorted shares.
• Koyfin: Gives readers access to comprehensive short-interest data across different stocks.

Days-to-Cover Ratio

The days-to-cover ratio, aka the short interest ratio, is calculated by dividing the total short interest by the stock’s average daily trading volume. This particular ratio specifies how many days it would take for all of the short sellers to cover their positions, assuming an average trading volume. A high days-to-cover ratio suggests that if the stock’s price starts to rise, short sellers could possibly struggle to cover their positions quickly, and that increases the potential for a short squeeze.

Unusually High Call Options Volume

A sudden increase in the volume of call options, especially those that are far out of the money, can also signal there is speculative buying afoot. Traders purchasing these options anticipate a big rise in the stock’s price, and speculative activity can contribute to upward price pressure, potentially resulting in a short squeeze as short sellers hop to it to cover their positions.

Significant Changes in the Put-Call Ratio

The put-call ratio measures the number of traded put options relative to call options. A high ratio indicates there is a bearish sentiment, and a low ratio suggests a bullish sentiment. A sudden change from high put activity to high call activity can indicate a big change in market sentiment, and that can mean a (you guessed it) short squeeze!

Behavioral and Market Sentiment Indicators

When you are able to understand what’s fueling the conversation and mood around a particular stock, it can absolutely help you see if and when a short squeeze could be brewing! There are definite market sentiment Easter eggs—from social media chatter to analyst attention—that signal when interest is piqued, and it’s about to get interesting.

Social Media Chatter and News Sentiment

The lion’s share of today’s market conversations start online—platforms like Reddit, Twitter (now called X), and Stocktwits are the spots where retail investors gather and turn certain stocks into overnight superstars. When a particular stock all of a sudden is a hot topic, it’s worth paying attention, as this chatter drives demand, especially in heavily shorted stocks, causing a buying frenzy that fuels a short squeeze. We saw this with GameStop stock, where conversations on Reddit’s WallStreetBets turned a heavily shorted stock into a huge rally.

How can you track the sentiment on social media? With the following:

• Hootsuite Insights: A tool that lets you monitor mentions and sentiment across social platforms so you can see the chatter as it’s happening.
• Sprout Social: Provides a breakdown of sentiment (positive, negative, neutral) for specific topics, which is useful for gauging the overall mood around a stock.
• StockTwits: A platform focused specifically on stock discussions—it shows trending stocks and user sentiment, giving a sense of where retail interest is.
• Swaggy Stocks: Analyzes Reddit and other social channels to track sentiment on popular stocks, and it’s really useful for getting a sense of any growing hype or caution around a stock.
• Context Analytics: Provides metrics on social media sentiment for stocks, and it gives data-driven insights on how discussions could possibly impact price movement.

Using the above tools, traders can monitor rising interest in specific stocks—an early warning that sentiment might be driving demand higher.

Unusual Media Coverage and Analyst Upgrades

When a heavily shorted stock starts showing up in the media or receives an analyst upgrade out of the blue, it attracts new attention from investors. Positive coverage from respected outlets or favorable comments from analysts can trigger buying interest, particularly in stocks with a high level of shorts. And this can be more than enough to kick-start a rally that forces short sellers to cover, which drives the price up even more.

A prime example is when an analyst reverses a previous bearish stance on a stock and issues an upgrade, citing a change in the company’s outlook. This is sending a signal to big investors that the stock’s potential has been reassessed, and new buyers will come aboard. Watching for sudden media and analyst attention is super helpful for traders to discover any stocks that might be on the verge of a squeeze.

Rising Implied Volatility

Implied volatility (IV) is like the market’s way of pricing in the expected swings in a stock’s price. When IV starts climbing, it usually means traders are getting ready for bigger price moves. In the context of a potential short squeeze, rising IV is a sign that traders are buying up options left and right, particularly call options, as they’re expecting the stock to move higher.

Higher IV can sometimes show that speculative buying is underway, and that adds pressure on short sellers who may be forced to buy back shares as the price goes up. Traders can track IV through options analytics tools or brokerage platforms that show real-time data on option prices and volatility. If you see IV spiking on a heavily shorted stock, this is a pretty good sign that traders are expecting action—and you might be on the verge of a short squeeze.

The signs we went over do not guarantee a squeeze, but they can give you a heads-up when something unusual is happening or gaining ground in the market.

Using Technical Analysis to Identify Potential Short Squeezes

Technical analysis is a really powerful tool for spotting short squeezes that are on the horizon, as there are some chart patterns and indicators that can accurately predict that a heavily shorted stock is on the cusp of making a strong upward move. Below, we’ll break down some of the main patterns and momentum indicators to look out for when evaluating stocks that have high short interest!

Key Technical Patterns

Certain price and volume patterns can be early signs of a squeeze, so here are the most common patterns to look out for:

• Breakouts: When a stock’s price pushes past a previously established resistance level, it’s known as a breakout. This move often signals that buyers are stepping up, possibly indicating a change in direction. In stocks with high short interest, a breakout can be the catalyst that drives short sellers to cover their positions. The more shares get bought, the more pressure short sellers feel, pushing the price even higher as they rush to exit their trades.
• Rising Trading Volume: Trading volume is like the pulse of the market, showing how much interest there is in a stock. When volume picks up noticeably during a price move, it’s a strong signal that demand is intensifying. If a heavily shorted stock sees its price rise along with a big volume spike, it’s a good indicator that there’s strong buying interest. This type of surge can quickly set off a squeeze, forcing short sellers to buy back shares to cut their losses and accelerate the price upward.
• Trend Reversals: Certain chart patterns, like double bottoms or the inverse head-and-shoulders, hint at a possible trend reversal. These patterns suggest that a stock might be shifting from a downtrend into an uptrend. For a heavily shorted stock, this reversal can be all it takes to push short sellers into action, scrambling to buy shares before the price moves too high. This panic-buying response can fuel the squeeze even further.

Momentum Indicators

Momentum indicators give traders a good sense of the strength behind a price move, and that helps them gauge whether a stock is building enough momentum to sustain a squeeze. The following are two of the biggest used momentum indicators for spotting upward trends in heavily shorted stocks:

• Relative Strength Index (RSI): The RSI measures the speed and scale of recent price changes on a scale from 0 to 100. Stocks with an RSI above 70 are generally seen as overbought, while those below 30 are considered oversold. When a heavily shorted stock has an RSI moving from oversold toward overbought, it suggests that demand is building up, and the stock could continue rising. For traders, this shift can be an early clue that the price has room to keep climbing, especially as short sellers start to feel the pressure to cover.
• Moving Average Convergence Divergence (MACD): The MACD tracks the relationship between two moving averages and is used to spot changes in momentum. A bullish signal occurs when the MACD line crosses above the signal line, hinting at possible upward movement. In a heavily shorted stock, this crossover can be a sign that buying momentum is gaining strength. The anticipation of higher prices can then lead more traders to jump in, further driving up demand and setting the stage for a squeeze as short sellers react.

Volume Analysis

Trading volume is one of the biggest indicators of investor interest, so when it spikes out of nowhere, especially during “green days” (when a stock closes higher than it opened), it can be a sign that more buyers are coming in. In the case of heavily shorted stocks, a sudden surge in volume could predict the early stages of a short squeeze.

Say there is a heavily shorted stock that’s been seeing relatively low volume. Then, on a given day, the volume suddenly triples while the stock price edges higher. This burst of buying interest can be a red flag for short sellers. It’s a signal that buyers are starting to move in, potentially preparing for a larger push. If this momentum continues over several days, it can lead short sellers to cover their positions, which adds even more upward pressure on the stock.

Volume analysis becomes particularly useful when paired with other indicators like breakouts or trend reversals. For instance, if a stock experiences a breakout above resistance along with a big volume spike, it’s more likely that the price will keep climbing as increased demand and buying pressure drive the stock upward.

In short (pun intended), a sudden increase in trading volume, especially on green days, can be an early sign that a short squeeze is brewing. For traders watching closely, volume spikes are a pretty big hint that demand is ramping up and that the stock may be on the brink of a major move.

Practical Steps for Options Traders When a Short Squeeze Is Likely

When a short squeeze seems like it’s going to bear fruit, there are a few ways for options traders to try and benefit from the coming spike! The right strategy, however, depends on way more than just getting in on a hot stock—you need to understand the risk that is involved, how to manage costs, and have a clear plan in place. Look below for some practical steps during a short squeeze!

Identify the Right Options Strategy

Different options strategies all come with different levels of risk and reward, so it’s super important to pick the one that matches your vision and comfort level:

• Buying Call Options: Buying calls is a popular approach when a stock looks set to go up. This lets you profit from the increase without the same level of risk as buying the stock outright since the maximum you can lose is the premium you pay. If the squeeze plays out strongly, a call option can provide a substantial upside.
• Call Spreads: A call spread is when you buy a call at one strike price and sell another at a higher strike. This approach limits the cost of entering the position, which can be handy when volatility is driving up prices. Call spreads cap your profits, and they also decrease the up-front premium, so it’s a more conservative way to play a squeeze.
• Selling Put Options: For the more experienced traders, selling puts is another way to take advantage of an expected squeeze. When you sell a put, you collect a premium and stand to gain if the stock price stays above the strike. But this approach comes with more risk since you could end up having to buy the stock if it dips below the strike price. This is best suited for those who are prepared to take on more risk if things don’t go as they expected them to.

Consider Implied Volatility and Its Impact on Options Pricing

Implied volatility usually surges in times of heavy speculation, and with a short squeeze, options premiums can jump up abruptly. Yes, this creates opportunities, but it’s also a good reminder to proceed with caution:

• High IV and Buying Calls: When IV is high, the options cost goes up, which can make calls pricey. If you’re buying options, it’s worth weighing whether the expected price movement will be big enough to justify the higher cost.
• High IV and Selling Puts: On the flip side, higher IV can mean bigger premiums for those selling puts. But keep in mind that high volatility also increases the risk of sudden price moves. Selling puts with elevated premiums is tempting, but it’s wise to approach this with a clear view of the potential risks.

Set a Plan and Know Your Risk Tolerance

Short squeezes can be explosive, but the fallout can be really unpredictable. That’s why having a plan and sticking to it is a must so you can avoid any impulsive moves when the market gets choppy:

• Establish Entry and Exit Points: Decide in advance at what price you’ll enter and exit the trade. Having these points set can help keep you grounded during fast market moves.
• Use Stop-Loss Orders: Consider using stop-loss orders to limit downside if the trade doesn’t go as expected. Knowing your max loss before you start helps keep any surprises to a minimum.
• Manage Position Size: Make sure the size of your position aligns with what you’re prepared to risk. Short squeezes can be volatile, so it’s wise not to overextend on a single trade.
