A-Share Screening by Opening Gain, Turnover, and Intraday Range
Summary
This stock-selection rule screens for shares with an amplitude above 1%, turnover above 2% and no more than 9%, and a 9:25 price gain below 6%. The stated rationale is to combine a measure of price movement with trading activity and a short-term opening signal. The page includes a formula reference and sample Python that queries Chinese equity data, filters securities, and returns a list of candidates. It also mentions sorting by market interest, though the sample code shown does not implement that ranking.
The page provides no backtest, return series, benchmark, or evidence that the thresholds predict future performance. It warns that the conditions are narrow and that a single pre-open observation cannot represent long-term value, suggesting additional technical and fundamental filters. The examples also appear inconsistent about the timing and direction of the opening-price condition, and the formula’s lookback reference is not fully explained. Treat the thresholds as a screening illustration that requires verification and testing before use.
Key ideas
- The screen combines price amplitude, turnover, and a short-term opening-price condition.
- The stated thresholds are amplitude above 1%, turnover above 2% and up to 9%, and a 9:25 gain below 6%.
- The sample material includes both an indicator formula and a Python stock-filtering example.
- The page presents no performance evidence and cautions that the criteria are limited.
- The formula and Python example differ in how they represent the opening-price condition.
