Screening Main-Board Stocks by Turnover, Reversal, and Prior-Day Low

Summary

This stock screen combines a turnover-rate band of 3% to 12%, a reversal-style candle condition, and a close above the previous day’s low. It applies the filters to main-board stocks. The article describes the reversal condition through a measure based on the prior close’s relative position within the day’s high-low range, and it ranks candidates by market value in its example screening expression.

The rationale is to combine trading activity and a reversal pattern with a price condition suggesting the stock has held above the prior session’s low. The document provides formula and Python examples, but no backtest, returns, benchmark comparison, or evidence that the filters predict future performance. It also notes that the screen uses technical and trading data without assessing company fundamentals, and suggests adding other technical and fundamental measures. Its sample code has data-source and implementation details that require independent checking before use.

Key ideas

• The screen selects main-board stocks with turnover between 3% and 12%.
• It combines a reversal-style candle filter with a close above the previous day’s low.
• The article gives screening and coding examples but reports no performance test.
• The filters omit fundamental analysis and may select companies of uncertain quality.
