Screening Stocks by Price Range, Float Size, and Market Capitalization

Summary

This stock screen combines three filters: price amplitude greater than 1, free float no more than 5.5 billion shares, and company size above 200 million. The article interprets the amplitude condition as a way to find more volatile stocks that may suit short-term trading, while the float and size filters aim to balance a limited share supply with a minimum company scale. Its code examples intersect the conditions and rank qualifying names by turnover rate, retaining a fraction of the candidates.

The article provides selection logic and sample implementations, but no backtest results or evidence that the criteria improve returns. It cautions that the screen omits financial health and company fundamentals, and that market-wide moves or company-specific events can dominate the signals. Suggested refinements include adding fundamental measures, adjusting the size range for industry and market conditions, and reviewing selections over time. The screen does not specify position sizing, execution, holding period, or a tested risk-control process.

Key ideas

• The screen requires amplitude above 1, free float at or below 5.5 billion shares, and size above 200 million.
• The stated aim is to find volatile stocks with limited float and a minimum scale.
• The examples rank qualifying shares by turnover rate and keep a subset of candidates.
• The document reports no backtest evidence for the selection rules.
• It identifies missing fundamental analysis and exposure to market or company events as risks.
