Screening Shanghai-Listed Stocks for Range and Recent Price Strength

Summary

The proposed stock screen combines a daily range threshold, a Shanghai-market code prefix, and a recent upward move within the prior 25 sessions. The accompanying explanation treats a wider range as a sign of volatility and recent strength as a possible momentum signal. It also suggests ranking candidates by their position relative to the recent 50-session high and low, and recommends adding technical and fundamental filters.

There is a material mismatch between the stated idea and the sample formulas: the description refers to a limit-up event, while the code checks for at least one session whose close is no lower than the previous close. That does not establish a limit-up. The article provides no backtest or returns evidence, and warns that recent performance may not persist and that a narrow screen can omit relevant fundamentals. The thresholds and ranking rule are presented as a screening recipe, not a validated trading strategy.

Key ideas

• The screen selects Shanghai-coded stocks with a daily high-low range above one percent and a recent positive close-to-close move.
• The explanation associates wider ranges with volatility and recent strength with potential continuation.
• A ranking based on the recent trading range is suggested for sorting candidates.
• The sample condition does not verify a limit-up event, despite the prose describing one.
• No performance test is supplied, and the article recommends considering other technical and fundamental information.
