Screening A-Shares by Price Range, Convertible Bonds, and Positive Returns

Summary

The document presents an A-share stock screen based on price amplitude above 1%, an available convertible-bond name, and positive returns. Its explanation frames these filters as a combination of stock movement and company-related information, and suggests adding valuation or earnings-growth measures for a broader assessment. It cautions that positive historical returns do not ensure future gains and that the screen may miss some smaller or volatile companies.

The sample formulas and Python reference introduce substantial inconsistencies. The formula adds a market-capitalization threshold and a code exclusion, while the Python example adds geographic, industry, turnover, and market-value filters and does not directly calculate the stated amplitude condition. Some variable names and data selections also make the intended measurements unclear. The article offers no backtest or evidence of returns, so the stated screen and code should be treated as separate, unvalidated examples rather than a reproducible strategy.

Key ideas

• The stated screen uses amplitude above 1%, convertible-bond availability, and positive returns.
• The document notes that historical gains do not guarantee future performance.
• It proposes valuation and earnings-growth measures as possible additional filters.
• The provided formulas and Python example add conditions that differ from the stated rule.
• No backtest or performance evidence is included.
