Screening Shenzhen Main Board Stocks by Valuation, RSI, and Opening Move

Summary

This Chinese stock screen selects Shenzhen Main Board companies with RSI below 65, positive price-to-earnings ratios below 29.01, price-to-book ratios below 3.11, and a gain under 6% at 9:25. The accompanying code reference also filters for circulating market capitalization of at least 10 billion yuan and orders candidates by that measure, so the implementation details do not perfectly match the prose description. The stated rationale is to avoid especially sharp early rises while retaining stocks within valuation bounds.

The document warns that a snapshot near the open can be noisy and may distort selections. It suggests adding fundamental, industry, and market-activity information, and ranking stocks using those considerations. It supplies no backtest, returns, or evidence that the screen improves performance, and its code has apparent syntax or data-definition gaps. The thresholds describe a proposed filter, not a validated strategy, and the timing of the snapshot makes data quality and execution assumptions especially relevant.

Key ideas

• The screen combines an RSI ceiling with price-to-earnings and price-to-book bounds.
• It filters Shenzhen Main Board stocks using the observed move at 9:25.
• The stated rationale is to avoid stocks that have already risen sharply before the open.
• The code adds a market-capitalization filter that is not fully consistent with the prose.
• The document gives no performance evidence and cautions that opening snapshots can be noisy.
