Screening Chinese Stocks by Range, Ten-Day Return, and Convertible Bonds

Summary

This document presents a Chinese equity screening rule combining three conditions: daily price range above 1%, a positive ten-day return below 35%, and a nonempty name for an outstanding convertible bond. The range condition is described as a way to select stocks with more volatility, while the return band aims to avoid stocks that have already risen too sharply. The convertible-bond filter selects companies with bonds that have not been redeemed. The post also includes example screening logic and code references, but does not provide a backtest or performance evidence.

The stated rationale is that outstanding convertible bonds may indicate cash-flow pressure, which could be associated with higher stock risk. The post cautions that the rule can shrink the eligible universe and omit other drivers of prices. It suggests combining the screen with valuation and company financial measures, and discusses changing the bond-status condition to broaden selection or reduce risk. These explanations are hypotheses rather than demonstrated causal relationships, and the document gives no evidence that the combined screen produces profitable trades. The rule should therefore be understood as a candidate filter, not a validated strategy.

Key ideas

• The screen combines daily range, ten-day price performance, and outstanding convertible-bond status.
• The return filter seeks stocks with recent gains while excluding those above the stated upper bound.
• Outstanding convertible bonds are treated as a possible indicator of cash-flow pressure and added risk.
• The rule may reduce the available stock universe and leaves other price drivers unmodeled.
• The document offers no backtest results establishing the screen’s effectiveness.
