Mainboard Stock Screening with RSI and Daily Price Gains

Summary

This post describes a Chinese A-share screening rule that combines a relative strength index threshold with positive daily price movement. It selects mainboard stocks whose RSI is below 65, whose daily gain exceeds 1%, and whose reported daily return is positive. The stated rationale is to combine a technical condition with market strength and a mainboard listing filter, in the hope of finding stocks with favorable near-term performance.

The post supplies sample query and Python snippets, but it does not provide a backtest, performance figures, or evidence that the rules predict future returns. Its explanation also labels an RSI below 65 as oversold, which is not the usual oversold threshold, and describes the mainboard filter as evidence of sound fundamentals without defining a fundamental test. The author cautions that fixed rules can fall out of step with market conditions and that technical signals can be false. Industry or other indicators and dynamic adjustment are suggested as possible refinements.

Key ideas

• The screen requires RSI below 65, a daily gain greater than 1%, and a positive daily return.
• It limits candidates to mainboard stocks.
• The post gives query and Python examples but reports no backtest or measured performance.
• Fixed thresholds and technical signals may fail as market conditions change.
