A-Share Screen for Low-Priced Convertible-Bond Issuers by Turnover

Summary

This A-share stock screen selects securities with daily amplitude above a threshold, a nonempty name for an outstanding convertible bond, and a price below the stated cutoff. It then ranks candidates by average turnover. The accompanying Python example adds valuation filters based on price-to-book and trailing price-to-earnings measures, along with exclusions and checks on recent trading data. The article presents these rules as a way to combine price movement, a convertible-bond-related company attribute, valuation, and liquidity.

The document supplies screening logic and example implementation, but no historical performance or evidence that the criteria identify undervalued stocks or future winners. It notes that macroeconomic and policy conditions are omitted, and that the screen may miss high-growth companies. It suggests considering industry conditions, competitive position, growth measures, or technical timing filters. The criteria are therefore candidate filters, and the article does not establish that its valuation or trading assumptions hold across stocks or market regimes.

Key ideas

• The screen combines a daily price-amplitude threshold, an outstanding convertible-bond name, and a low share-price cutoff.
• Candidates are ranked by average trading turnover.
• The Python example adds price-to-book and trailing price-to-earnings filters.
• The screen omits macroeconomic and policy factors and may exclude high-growth stocks.
• No backtest or performance evidence is provided for the selection rules.
