Stock Screen Using Turnover, the 10-Day Average, and Recent Price Surges

Summary

This A-share screening rule requires turnover between 3% and 12%, an opening price within 5% of the 10-day moving average, and at least one session with a gain of 10% or more during the previous 25 trading sessions. The document frames these conditions as a way to combine trading activity, proximity to a short-term average, and evidence of recent large price moves. It provides formula examples and a Python sketch for implementation.

The article warns that the screen ignores company finances and industry position. It also notes that a large single-day gain threshold may reduce the candidate pool and raise the chance of overfitting. No backtest, sample size, or performance statistics are supplied. The code’s handling of turnover and moving-average comparisons may not directly match the stated day-level rules, so implementation details and data definitions need checking before any evaluation. The rules identify candidates but do not specify entry timing, exits, or position sizing.

Key ideas

• The screen sets turnover between 3% and 12% and requires the opening price to be within 5% of the 10-day moving average.
• At least one session in the previous 25 trading days must have gained 10% or more.
• The large-gain condition may shrink the candidate set and increase overfitting risk.
• The article supplies no performance evidence and omits fundamental analysis and trade-management rules.
