Biopharmacudical penny stocks

Screening Filters

1. Price: 0.10 – 5 USD

   • Purpose: Capture “penny stocks.”
   • Rationale: In U.S. markets, “penny stocks” are commonly defined as stocks trading under about $5 per share. Setting the price ceiling at $5 directly targets this category, while the $0.10 floor helps avoid extremely illiquid or distressed sub-penny names that may be more like shells than functioning companies.

2. Market Cap: 50M – 2B USD

   • Purpose: Focus on smaller, higher-risk, higher-upside companies typical of penny stocks, while filtering out micro shell companies.
   • Rationale:
     • Biopharmaceutical “penny stocks” are rarely large caps, so capping at $2B keeps us in small/mid-cap territory.
     • A minimum of $50M avoids the very smallest, often non-operational or extremely speculative entities that can skew results and be hard to research.

3. Monthly Average Dollar Volume: ≥ 300,000 USD

   • Purpose: Ensure some minimum liquidity so the stocks can reasonably be traded.
   • Rationale: Many penny biopharma names trade very thinly. By requiring at least $300k in average dollar volume per month, the filter aims to:
     • Reduce exposure to illiquid tickers with wide bid-ask spreads.
     • Make sure results are at least somewhat tradeable in practice.

4. Sector: Healthcare

   • Purpose: Align with the “biopharmaceutical” focus.
   • Rationale: Biopharmaceutical companies fall under Healthcare. Narrowing to this sector ensures you’re not getting cheap stocks from unrelated areas like Energy or Financials.

5. Industry: Biotechnology & Medical Research

   • Purpose: Target the core biopharma business model.
   • Rationale: Biopharmaceutical firms are typically categorized under Biotechnology & Medical Research. This industry filter emphasizes companies involved in drug discovery, development, and related medical research, which is exactly what most users mean by “biopharmaceutical.”

6. List Exchange: XNYS, XNAS, XASE (NYSE, Nasdaq, NYSE American)

   • Purpose: Restrict to major U.S. exchanges.
   • Rationale: Many penny stocks trade OTC, where reporting and liquidity can be poor. Limiting to NYSE, Nasdaq, and NYSE American:
     • Increases the likelihood of more stringent listing standards and better disclosure.
     • Makes it easier to research and trade the names versus OTC or pink-sheet listings.

7. Is Optionable: False

   • Purpose: Focus on smaller, less-institutional names that more often match “penny stock” profiles.
   • Rationale: Stocks with listed options tend to be larger or more actively traded. By excluding optionable names, the screen tilts more toward early-stage or niche biotech names that are less likely to have developed derivatives markets yet—more typical of biopharma penny stocks.

Why Results Match

• The price range explicitly captures the “penny stock” definition (sub-$5).
• The sector and industry filters narrow results to biopharmaceutical-type businesses within Healthcare and Biotechnology & Medical Research.
• The market cap and exchange constraints steer away from giant pharmas and ultra-tiny shells, landing on smaller, listed biopharma companies that fit the spirit of “biopharmaceutical penny stocks.”
• The liquidity and non-optionable checks refine the universe toward tradable, but still early-stage and speculative, biotech names consistent with what investors usually seek when asking for biopharma penny stocks.
