A-Share Stock Screening by Trading Range, Convertible Bonds, and Liquidity

Summary

This post proposes screening Chinese A-share stocks using a daily price-range threshold above one percent and a requirement related to outstanding convertible-bond names, then ranking candidates by average traded value. Its stated rationale combines trading activity and volatility with a market-attention signal. The proposed implementation also adds valuation filters, excluding stocks with missing financial data, price-to-book above 1.5, or negative trailing price-to-earnings values, and applies further listing and price-limit exclusions.

The post discusses risks from macroeconomic conditions and policy changes, and suggests considering industry trends, competitive advantages, and growth measures such as return-on-equity growth. However, it provides no backtest, performance evidence, or careful validation of the screening logic. The heading's popularity-ranking description also differs from the final rule, which ranks by average traded value, so the precise intended signal is not fully consistent.

Key ideas

• The proposed screen selects A-shares with a daily high-low range above one percent and a convertible-bond-name condition.
• The final ranking rule orders candidates by average traded value.
• The example adds valuation and listing-related filters, including a price-to-book ceiling of 1.5.
• The author identifies macroeconomic and policy shifts as potential sources of screening errors.
• No backtest or performance evidence is presented, and the description of the ranking signal is inconsistent.
