Screening Stocks for a Sharp Daily Decline and Other Filters

Summary

This proposed stock screen selects shares whose largest decline for the day falls between four and five percent below zero. The article frames the move as a possible source of short-term rebound potential and adds filters for market capitalization, valuation, and one-year performance. It also mentions restricting the selection to a stated calendar year and sorting by capital intensity, though these details are not consistently reflected in the final logic.

No backtest results, benchmark, or empirical evidence support the rebound rationale. The article notes that a short-term focus can overlook longer-term value and that the screen cannot reliably predict future prices. Its sample code contains inconsistencies between the stated filters and the fields or conditions shown, so it should be treated as an outline rather than a validated implementation.

Key ideas

• The core screen targets stocks with a daily decline between four and five percent.
• The stated rationale is that a sharp decline may precede a rebound.
• The proposed additional filters include market capitalization, valuation, and annual performance.
• The article supplies no evidence that the screen predicts rebounds.
• The example code does not consistently match the written selection rules.
