Combining Volume Ratio, Limit-Down Pricing, and Ten-Day Returns in a Stock Screen

Summary

This stock screen combines three conditions: a high volume ratio, a large absolute difference between the previous day’s limit-down price and its opening price, and a positive ten-day return below 35%. The document describes selecting the top 100 stocks by volume ratio and the top 100 by the stated price difference, then applying the return range. It interprets strong relative volume as possible buying interest and the prior limit-down pricing signal as evidence of a sharp selloff, but gives no performance results. The method description is brief and the accompanying code section is incomplete.

The author notes that high-volume ranking may overlook less-traded candidates, a sharp prior decline may continue, and a modest positive return may not persist. Suggested refinements include adding market capitalization and valuation filters, as well as technical indicators such as MACD or Bollinger Bands. These suggestions are not specified as tested improvements, so the screen remains a rough set of candidate-selection rules rather than a validated trading strategy.

Key ideas

• The screen uses volume-ratio ranking, a prior-session limit-down price comparison, and a positive ten-day return below 35%.
• It proposes taking the top 100 by volume ratio and by the absolute price difference described.
• The document offers interpretations of the signals but reports no performance evidence, and its code section is incomplete.
• High-volume and prior-selloff filters can miss candidates or select stocks that continue falling.
• Suggested additional filters include valuation, market capitalization, and technical indicators.
