Short Squeeze Risk Assessment
UPST Short Squeeze Score
High short squeeze risk. Significant short pressure combined with low liquidity. Potential for a sharp upward movement.
The Squeeze Score quantifies the current short squeeze risk by analyzing short interest, Days to Cover, and market liquidity. Use this score to quickly identify the most shorted stocks with the highest squeeze potential.
- 0.0–0.2: Very low short squeeze risk.
- 0.2–0.4: Low short squeeze potential.
- 0.4–0.6: Moderate short squeeze risk.
- 0.6–0.8: High short squeeze risk.
- 0.8–1.0: Extreme short squeeze risk.
Short Interest Ratio (% of Float)
The Short Interest Ratio (or % of Float) is the most critical metric for identifying the most shorted stocks. It reflects the percentage of available trading shares currently sold short.
Interpretation:
- 0%–5%: Very low short interest, minimal squeeze risk.
- 5%–10%: Moderate short interest, watch for trends.
- 10%–20%: High short interest, potential for squeeze.
- >20%: Extremely high, short squeeze risk elevated.
Key Short Selling Metrics

Short interest ÷ average daily volume.
It would take 2 to 5 days to cover short positions, posing moderate risk.
Decrease in short interest, signaling reduced selling pressure.
Bi-weekly observations in the stored history.

Frequently Asked Questions (FAQ)
What is short interest?
Short interest represents the number of shares sold short but not yet covered. It reflects bearish sentiment and short-selling pressure.
What does Short Interest % of Float mean?
This metric indicates what percentage of a company’s tradable float is currently held as short positions. Higher percentages imply stronger short pressure.
What is considered high short interest?
Typically:
• 5%–10%: Moderate
• 10%–20%: High
• 20%+: Extremely high with elevated squeeze risk
What is a short squeeze?
A short squeeze occurs when short sellers rush to cover their positions as the stock price rises, accelerating the upward movement.
What is Days to Cover (DTC)?
Days to Cover equals short interest divided by average daily trading volume. Higher DTC means shorts need more time to exit their positions.
What level of Days to Cover is risky?
• <2 days: Low risk
• 2–5 days: Moderate
• 5+ days: High squeeze potential
• 7–10 days: Extreme risk zone
What causes a short squeeze?
Common triggers include strong earnings, breakouts, upgrades, high volume, low float, or extreme short interest combined with rising prices.
What is a Short Squeeze Score?
It is a composite rating reflecting squeeze risk using short interest, DTC, liquidity, and momentum factors.
Can a stock with low short interest still squeeze?
Yes. Low float or sudden momentum can still trigger squeezes, though the probability is lower than highly shorted stocks.
How often is short interest updated?
FINRA updates short interest twice each month (bi-weekly). Market platforms refresh once the data is released.
Does short interest data get delayed during a U.S. government shutdown?
FINRA is not a government agency, so its operations do not stop during a federal shutdown. However, short interest data can still be delayed indirectly because the reporting and regulatory infrastructure involves broker-dealers and certain SEC processes.
During prolonged shutdowns, minor delays have occurred historically, but FINRA generally continues releasing bi-weekly short interest updates with minimal disruption.
Are short squeezes predictable?
You can identify high-risk conditions, but timing is inherently uncertain. A squeeze requires both high short interest and positive momentum.
Does high short interest guarantee a squeeze?
No. High short interest often reflects negative fundamental expectations and may not result in a squeeze if price pressure does not rise.
