Screening Profitable Small-Cap A-Shares with Convertible Bonds and Price Range

Summary

This stock-screening concept targets Chinese A-share companies with positive earnings, market capitalization below the stated ceiling, a daily high-low range above the stated threshold, and a nonempty name for an outstanding convertible bond. The document presents the filters as a way to combine price movement, company size, profitability, and a convertible-bond condition. It also provides example formula and Python implementations, though the examples do not cleanly establish that every stated condition is applied consistently.

The author argues that profitability and a size limit may favor smaller profitable firms, while acknowledging that this could exclude larger companies and unprofitable businesses with growth potential. Suggested refinements include loosening the size cap and adding technical filters. No backtest, return series, or comparison against a benchmark is supplied, so the rationale remains a screening hypothesis. The stated conditions and code should be checked carefully before use, particularly around how the filters are implemented.

Key ideas

• The screen combines positive earnings, a market-cap limit, a price-range threshold, and an outstanding convertible-bond name condition.
• The stated goal is to find smaller profitable A-share companies with some recent price movement.
• The document warns that profitability and size filters can exclude growth firms and larger companies.
• It offers example implementations but no backtest or benchmark comparison.
