Which stocks have high short float

Screening Filters

1. region: United States

   • Purpose: Limit results to U.S.-listed companies.
   • Rationale: You specifically asked about the US market, so this filter ensures we only look at U.S. stocks and exclude foreign listings.

2. list_exchange: ['XNYS', 'XNAS', 'XASE'] (NYSE, NASDAQ, AMEX)

   • Purpose: Focus on major U.S. exchanges.
   • Rationale: High-short-float names can exist on smaller venues, but NYSE/Nasdaq/AMEX concentrate most of the liquid, institutionally followed stocks. This reduces obscure or illiquid names and focuses on more tradable, better-regulated markets.

3. short_ratio: ['MoreThan30Pct']

   • Purpose: Identify stocks with a high short float.
   • Rationale: “High short float” is operationally defined here as short interest greater than 30% of the float, which is generally considered elevated and indicative of strong bearish positioning or crowding on the short side. This is the core filter that directly answers your question.

4. market_cap: {'min': '5000000000'} (≥ $5B)

   • Purpose: Restrict to mid/large-cap companies.
   • Rationale: Many micro- and small-caps can have extreme short percentages but are very speculative and easily manipulated. A $5B+ market cap threshold helps focus on more established companies where high short float may reflect meaningful fundamental or thematic controversy, not just illiquidity.

5. price: {'min': '10'} (share price ≥ $10)

   • Purpose: Avoid very low-priced or penny stocks.
   • Rationale: Low-priced shares often have distorted percentage moves and can show extreme short metrics due to small floats or trading anomalies. A price floor around $10 helps ensure results are more investable and less driven by penny-stock dynamics.

6. monthly_average_dollar_volume: {'min': '2000000'} (≥ $2M per month)

   • Purpose: Guarantee a minimum level of liquidity.
   • Rationale: High short float in illiquid stocks is risky and can be hard to trade in or out of. A dollar-volume filter screens for names where a reasonable amount of capital changes hands, making the high short interest more actionable.

7. is_optionable: 'True'

   • Purpose: Include only stocks with listed options.
   • Rationale: High-short-float stocks are often traded with hedging or speculative option strategies. Ensuring the stock is optionable makes the list more relevant for traders and investors who may want to manage risk or express a view using options.

Why Results Match Your Question

• The U.S. region and major exchange filters ensure all results are U.S. stocks in mainstream markets, aligning with “US market.”
• The short_ratio > 30% filter directly targets stocks with high short float, satisfying the main condition in your query.
• The market cap, price, and liquidity filters refine the universe to more investable, established, and tradable names—so the high short float is more likely to reflect significant market sentiment rather than micro-cap or penny-stock noise.
• The optionable filter makes the resulting list more practical for active strategies that often accompany trading in high-short-float stocks.
