A-Share Screening by Daily Range, Turnover, and Share Price

Summary

This proposed A-share screen selects stocks with a daily range above 1%, prior-day trading activity above a stated threshold, and a share price below a stated ceiling. The rationale is to find lower-priced stocks with substantial price movement and trading activity. The post includes brief formula and Python examples for calculating the range and combining the filters.

There is no backtest, performance report, or empirical support for the claim that this combination could produce quick gains. The implementation details are inconsistent: the text specifies yesterday’s trading amount, while the formula references prior volume and the Python example compares a volume field to the threshold. The post also cautions that the rules ignore financial condition and business prospects, and that low-priced shares can fall further. It suggests combining the screen with fundamental and technical analysis or tightening the thresholds, without specifying or testing a revised strategy.

Key ideas

• The screen combines a daily range above 1%, prior-day activity above a stated threshold, and a share price below a stated ceiling.
• The post frames the conditions as a way to identify volatile, actively traded, lower-priced stocks.
• The written rule calls for trading amount, but the examples use volume, so the activity measure is not implemented consistently.
• No backtest or return evidence is supplied for the proposed screen.
• The article warns that the rules omit company fundamentals and that low share prices do not prevent further losses.
