Chinese Stock Screen Using RSI, Daily Gains, Size, and Profitability

Summary

This Chinese-language article describes a mainland China stock screen combining technical and fundamental filters. It selects main-board shares with RSI below 65, a daily gain above 1%, market capitalization below 10 billion yuan, and positive net profit. The intended rationale is to find smaller profitable firms showing recent price strength, although the article incorrectly characterizes an RSI below 65 as oversold. Its code also refers to additional valuation and indicator conditions, so the implementation does not cleanly match the stated screen.

The article warns that fixed thresholds can miss changing market conditions and exclude stocks outside the chosen size and profitability bands. It suggests adding indicators and adjusting the capitalization limit as conditions change. It provides no backtest, return figures, or evidence that the screen predicts future performance, and its selection logic is not a complete trading strategy: it does not specify entries, exits, position sizing, or portfolio risk controls.

Key ideas

• The stated screen combines RSI below 65, a daily gain above 1%, a main-board listing, a size ceiling, and positive net profit.
• The article frames RSI as an oversold signal, though a reading below 65 alone does not establish oversold conditions.
• The code includes extra filters that differ from the screen described in the text.
• Fixed thresholds can become poorly suited to changing market conditions.
• The article gives no backtest or rules for trade execution and portfolio risk.
