A-Share Screen Using Price Range, Turnover, and Relative Strength

Summary

This document outlines a short-term Chinese stock selection screen based on price movement, trading activity, and relative strength. Its stated logic selects shares with an amplitude threshold, actual turnover within a specified range on the prior day, and higher turnover yesterday; the final selection description also adds a high relative-strength reading. The reference formulas express the amplitude and turnover conditions and rank a 14-period RSI, retaining stocks near the top of that ranking.

The article frames turnover and amplitude as signs of activity and recent market behavior, but gives no backtest or evidence that the conditions predict returns. It warns that the screen may overlook company fundamentals and broader market dynamics, and suggests adding financial or macroeconomic measures. The provided formula and Python examples do not fully align with the prose about which day’s turnover is measured, so the intended timing and thresholds should be verified before implementation. No exit rules, position sizing, or risk controls are specified.

Key ideas

• The screen combines price amplitude with turnover conditions across recent sessions.
• The final selection description adds a high-ranked relative-strength reading using a 14-period RSI.
• The article provides formula and Python examples but no performance results.
• The author notes that turnover-based selection can omit company fundamentals and changing market conditions.
• The prose and example calculations differ in how turnover timing is expressed.
