Chinese Stock Screen Using Price Range, Convertible-Bond Listing, and Prior Low

Summary

This proposed Chinese equity screen selects stocks with a daily high-low range of at least 1%, a nonempty name for an outstanding convertible bond, and a closing price above the previous day’s low. The article frames these filters as a combination of price volatility, financing-related information, and a simple sign of price recovery. It provides a technical formula and Python example, and discusses adding indicators such as MACD, RSI, or volume changes for further screening.

The rule is simple and the document gives no backtest results or evidence that the convertible-bond condition predicts stock performance. Its explanation cautions that the screen may select low-quality or temporarily popular stocks and does not assess company value, valuation, or prospects. The sample implementation also appears inconsistent with the stated convertible-bond filter: it queries financial indicators and excludes some firms based on a dividend field rather than checking the outstanding bond name. That discrepancy, along with the need to verify data definitions and market coverage, should be resolved before relying on the example.

Key ideas

• The screen combines a minimum daily price range, an outstanding convertible-bond name, and a close above the prior day’s low.
• The article interprets the conditions as price, financing, and market-sentiment filters.
• The sample implementation does not clearly implement the stated convertible-bond condition.
• No predictive evidence is presented, and the rule omits company valuation and business prospects.
