Screening Stocks by Range, Ten-Day Gain, and Prior Limit-Up Status
Summary
This Chinese equity screen selects stocks with a daily trading range above 1%, a ten-day price gain above zero but below 35%, and no limit-up close on the previous day. The stated rationale is to find shares showing some recent movement and positive momentum while avoiding names that have just reached the daily price ceiling. The post includes a short formula reference and a Python sketch, but the code does not clearly implement every stated condition: it filters on range and prior limit-up status, while the ten-day return is calculated but not used as a filter.
The author notes that a short lookback can miss longer-term opportunities and that the screen uses too few factors to reflect company fundamentals or broader market conditions. Suggestions include adding indicators and fundamental data, extending the evaluation window, and considering market context. No backtest or evidence of profitability is presented, so the conditions remain an unvalidated screening hypothesis.
Key ideas
- The screen requires a daily range above 1%, a positive ten-day gain below 35%, and no limit-up session on the previous day.
- The rationale combines recent price movement with a moderate-gain filter and a limit-up exclusion.
- The example code does not visibly apply the ten-day return as a selection condition.
- The post identifies the short horizon and limited number of factors as key weaknesses.
