Chinese A-Share Screen for Daily Range and Gains Above One Percent

Summary

This note presents a short-term Chinese equity screen for shares whose codes begin with 60, whose daily range exceeds 1 percent, and whose daily gain is above 1 percent. The stated rationale is to focus on a particular stock-code segment, identify securities with notable intraday movement, and require a positive price move. Formula and Python examples illustrate how to apply each condition using daily high, low, prior close, code, and percentage change data.

The document provides no historical test, transaction assumptions, or evidence that the screen produces positive returns. It cautions that a few technical or financial variables cannot capture a stock’s full value or risk, that market conditions can change the screen’s results, and that focusing on a single day’s rise may overlook business fundamentals. It suggests adding technical and financial factors, considering a multi-factor approach, and reviewing fundamentals and industry trends. The screen is therefore a simple candidate filter, not a fully specified entry, exit, or portfolio strategy.

Key ideas

• The screen requires a code beginning with 60, a daily range above 1 percent, and a daily gain above 1 percent.
• The examples calculate range against the prior close and filter on the stock code and daily return.
• The proposed rationale is to focus on a specified stock segment with active movement and a positive session.
• No backtest or performance evidence is supplied.
• The note recommends broader fundamental, technical, and industry analysis to address the screen’s limits.
