How does a short squeeze happen?

A short squeeze occurs when a heavily shorted stock rapidly increases in price. Short sellers are forced to buy shares back at higher prices to cover their positions, creating a feedback loop of upward price momentum.

What is Days to Cover (short ratio)?

Days to cover is calculated by dividing the total shares shorted by the average daily trading volume. A ratio above 5 days is considered high — it means shorts need significant time to exit, increasing squeeze potential.

Most Shorted Stocks 2026: Short Interest Rankings & Squeeze Candidates

Q: What makes a stock a good short squeeze candidate?

A good short squeeze candidate typically has a high short percentage of float (usually >20%), a high days to cover ratio, a relatively low public float, and a potential catalyst that could drive the price up unexpectedly.

Q: What is considered a high short interest percentage?

The average S&P 500 stock has roughly 2-3% short interest. Above 10% is elevated, above 20% is high, and above 30% is extreme. In our study, stocks above 20% are in territory where short squeezes become a real risk.

Top 20 Most Shorted Stocks by % of Float

Short Squeeze Screener

Filtered U.S. equities with market cap over $100M and average volume over 500K. The "Squeeze Prob" score multiplies Short % by Days to Cover — higher scores indicate more squeeze fuel.

⚠️ Risk Warning

Short squeezes are incredibly rare events. Stocks that are heavily shorted are usually in that position because the underlying business is distressed or overvalued. Chasing short squeezes is highly speculative and risky. Data is for informational purposes only.

How the Squeeze Score Works

Our Squeeze Score is a weighted composite of five measurable factors. Each contributes a maximum number of points, for a total possible score of 100.

Short % of Float 0–30 pts

The foundation. Higher short interest means more shares that must eventually be bought back. Above 30% is extreme.

Days to Cover 0–20 pts

Short ratio = shares short ÷ avg daily volume. Higher DTC means shorts need more days to exit — increasing squeeze pressure.

Price Momentum 0–20 pts

Positive 1M and 3M momentum suggest the tide is turning against shorts. Stocks already rallying put maximum pressure on bearish positions.

Short Interest Change 0–15 pts

Month-over-month change in shares shorted. Declining short interest signals a potential covering rally already underway.

Institutional Support 0–15 pts

High institutional ownership provides a price floor. When institutions hold tight, shorts have fewer shares to borrow.

How Short Squeezes Work

A short squeeze is a market phenomenon that occurs when a heavily shorted asset experiences a rapid price increase. Short sellers borrow shares and sell them, hoping to buy them back at a lower price. When the price rises instead, short sellers are forced to buy back shares to cut losses or meet margin calls — driving the price even higher in a cascading feedback loop.

Key Ingredients for a Squeeze

High Short Interest (>20% of float): Enough "fuel" — borrowed shares that must eventually be returned. The higher the short interest, the more buying pressure when shorts cover.
High Days to Cover (>5 days): A ratio above 5 means it would take over five days of normal volume for all shorts to exit. The longer it takes, the harder the squeeze.
An Unexpected Catalyst: Positive earnings, new products, buyouts, or massive retail buying can trigger the initial spike that forces short covering.
Low Float: Fewer available shares means each buy has a larger impact on price. Small-cap stocks with low floats are particularly susceptible.

Understanding what short selling is helps contextualize why these mechanics matter. Short sellers face theoretically unlimited losses — unlike regular investors who can only lose 100% of their investment.

Historical Short Squeeze Examples

GameStop (GME) — January 2021

The most famous short squeeze in modern history. GameStop had short interest exceeding 140% of its float — more shares were shorted than actually existed. A massive wave of retail buying, coordinated on social media, sent the stock from under $5 to over $120 (split-adjusted) in weeks. However, 89% of retail traders who chased the squeeze lost money.

AMC Entertainment (AMC) — June 2021

Following GME's footsteps, the struggling theater chain had over 20% short interest. Supported by retail enthusiasm and a reopening economy catalyst, AMC squeezed from $2 to over $70, severely punishing institutional short sellers.

Clover Health (CLOV) — June 2021

During the retail trading frenzy of mid-2021, Clover Health became a target with high short interest. The stock squeezed from around $9 to over $28 in just days before rapidly declining — illustrating the extreme risk of squeeze plays.

Volkswagen — October 2008

The original mega-squeeze. Porsche quietly accumulated a 74% stake in VW while hedge funds held massive short positions. When Porsche disclosed its position, VW briefly became the world's most valuable company as shorts scrambled to cover. The stock rose from €200 to over €1,000 in two days.

Key Findings

Methodology & Data Sources

Short interest data was sourced from HighShortInterest.com, which aggregates FINRA and exchange short interest reports (last updated February 13, 2026). We included all stocks with short interest above 20% of float across NASDAQ, NYSE, and AMEX exchanges — totaling 76 stocks in our core rankings.

Squeeze Score data was aggregated from Yahoo Finance and SEC EDGAR filings for 65 US-listed stocks. Each stock is scored using our proprietary Squeeze Score — a 5-factor composite (0-100) weighing short % of float, days to cover, price momentum, short interest change, and institutional support.

Market capitalization was calculated from current share price × total shares outstanding. Price performance data was computed from historical closing prices via Yahoo Finance chart API. P/E ratios were sourced from StockAnalysis.com.

Update frequency: Monthly, aligned with FINRA's bi-monthly short interest reporting cycle. All data represents a point-in-time snapshot.

Frequently Asked Questions

What stock has the highest short interest right now?

As of early 2026, Groupon (GRPN) has the highest short interest at 46.06% of float, followed by Hertz Global Holdings (HTZ) at 44.41% and Better Home & Finance (BETR) at 43.93%. The majority of the most shorted stocks are in Health Care, Biotechnology, and Technology sectors.

What does high short interest mean?

High short interest means a large percentage of a stock's available shares (float) have been sold short by traders betting the price will decline. Short interest above 20% is considered very high and can indicate strong bearish sentiment — but it also increases the potential for a short squeeze if the price rises.

What makes a stock a good short squeeze candidate?

A good short squeeze candidate typically has: (1) high short % of float (usually >20%), (2) a high days-to-cover ratio (>5 days), (3) a relatively low public float, and (4) a potential catalyst that could drive the price up unexpectedly. Our Squeeze Score combines these factors into a single metric. See our screener above.

What is a good short ratio (days to cover)?

The short ratio measures how many days it would take all short sellers to buy back their shares based on average daily volume. A ratio above 5 days is generally considered high — shorts would need significant time to exit, increasing squeeze potential. Below 2 days means shorts can exit quickly.

Can short interest predict a short squeeze?

High short interest is necessary but not sufficient for a squeeze. A squeeze requires: (1) short interest above ~20% of float, (2) a high short ratio, (3) a catalyst driving the price up, and (4) limited available shares. Most heavily shorted stocks actually decline — only a small percentage experience squeezes. See our historical examples.

Do heavily shorted stocks outperform the market?

Not consistently. While short squeezes can produce dramatic short-term returns (GME gained 1,700% in 2021), the average heavily shorted stock underperforms the S&P 500 over 3-12 month periods. Stocks are usually shorted for fundamental reasons. The edge comes from identifying exceptions where the bearish thesis is weakening.

How often is short interest data updated?

FINRA requires broker-dealers to report short interest positions twice monthly — on the 15th and last business day. The data is published about 10 business days after, meaning it always has a 1-2 week lag. Daily short volume data is available from exchanges, but it's not the same as short interest (outstanding positions).

What is considered a high short interest percentage?

The average S&P 500 stock has roughly 2-3% short interest. Here are the thresholds: Below 5% — normal. 5-10% — elevated. 10-20% — high, significant bearish sentiment. 20-30% — very high, squeeze risk escalates. Above 30% — extreme, historically rare.
