A Stock Screen Combining RSI, Daily Gains, Board, and Listing Year

Summary

This document presents an equity screening rule for mainland Chinese stocks: select main-board companies with RSI below 65, a daily gain above 1%, and a specified listing year. It frames the RSI condition as a way to identify stocks that may be oversold, while the positive daily move is intended to capture strength. The listing-year filter further narrows the universe. Indicator formulas and sample code are included as implementation references, but the post supplies no backtest results or performance evidence.

The author cautions that fixed filters can lag changing market conditions and that a listing-year restriction may omit promising companies. Suggested refinements include adding technical and fundamental measures and adapting filters to market conditions. The sample code has apparent inconsistencies with the stated rule: it derives the listing-year filter from the current year, and several referenced fields are not clearly constructed in the shown steps. Treat the screen as a hypothesis for research, not as a validated strategy; the document does not establish that its interpretation of RSI or its expected returns are reliable.

Key ideas

• The proposed screen combines an RSI ceiling, a positive daily return threshold, a main-board universe, and a listing-year filter.
• The RSI and daily-gain conditions are presented as signals for potential rebound and continued strength.
• The document offers indicator formulas and code examples but reports no backtest evidence.
• Static filters may become misaligned with changing market conditions.
• The sample implementation appears inconsistent with the stated listing-year condition and requires verification.
