Mainland China Stock Screen Using RSI, Daily Gains, and Turnover

Summary

The document describes a mainland China main-board stock screen combining three filters: RSI below 65, a daily gain above 1%, and previous-day turnover above 8%. Its stated rationale is to find stocks showing a positive short-term move and substantial trading activity while RSI remains below the chosen ceiling. The post characterizes the approach as mixing technical and fundamental considerations, although the listed selection criteria are primarily technical and market-activity filters.

It includes example query and Python-style implementation references, but provides no backtest results, performance data, or evidence that the screen forecasts returns. The author notes that fixed thresholds may not adapt to changing markets, that indicators can produce false signals, and that screening rules need risk controls. The rationale that RSI below 65 identifies an oversold condition is not established by the document, and RSI levels are commonly interpreted in context rather than as a standalone oversold test. Treat the rule as a screening example, not a validated strategy.

Key ideas

• The screen selects main-board stocks with RSI below 65, a daily gain above 1%, and prior-day turnover above 8%.
• The proposed rationale combines RSI, recent price strength, and trading activity.
• The post provides example implementation references but no evidence of historical or live performance.
• Fixed thresholds may become poorly suited to changing market conditions.
• The stated oversold interpretation of RSI below 65 is not demonstrated in the document.
