A Chinese Stock Screen Using Range, Opening Gain, and Rising DEA

Summary

This Chinese stock-selection post describes a screen combining three conditions: an amplitude measure above a threshold, a 9:25 price gain below a ceiling, and a rising DEA line from MACD. The stated rationale is to combine a measure of price movement with a short-term price condition and a medium-term momentum signal. It presents a formula reference and a Python example that attempts to retrieve market data and filter stocks.

The post offers no backtest, performance statistics, or comparison showing that the screen predicts returns. It warns that price-based criteria can miss company fundamentals and may be unreliable during volatile markets. It suggests adding fundamental measures and capital-flow or financing data, but does not test those additions. The code example’s implementation details do not fully establish that its data calculations match the stated stock-level conditions, so the screen should be treated as an unvalidated selection idea rather than evidence of an edge.

Key ideas

• The proposed screen combines price amplitude, a capped 9:25 gain, and rising MACD DEA.
• The author frames DEA as a measure of medium-term price movement.
• The post provides formula and Python references but no performance evidence.
• The screen may omit fundamental risks and may be unstable in volatile markets.
• Suggested extensions include valuation, profitability, and capital-flow measures.
