Screening Shanghai-Listed Stocks for Range and Recent Price Spikes

Summary

The post outlines a Chinese-equity screening rule that combines daily price range, a stock-code prefix beginning with 60, and a recent large upward move. It also suggests sorting qualifying stocks by market capitalization and provides example implementations for a charting platform and a Python data workflow. The proposed rationale is that greater movement and a recent sharp rise may identify candidates with short-term opportunity, though the post does not validate that premise with results.

The rule is stated inconsistently: the title refers to a 1% rise, while the body and charting formula specify a 10% intraday high relative to the prior close. The Python example uses a 1% range threshold based on the open, and its return-field scaling is unclear. These differences can materially change the selected universe. The author cautions that technical-only screening can miss fundamentals and that sharp gains may reflect speculation without persistence. No backtest, risk controls, or evidence of profitability is provided.

Key ideas

• The screen combines price range, a stock-code prefix, and at least one large gain during a recent 25-session period.
• The post proposes ranking selected stocks by market capitalization.
• The stated gain threshold conflicts between the title and the body, and implementations differ in their price references.
• The author warns that recent sharp gains may not persist and recommends combining technical and fundamental checks.
• The document provides no backtest evidence or risk-management rules.
