Stock Screening by Price Amplitude, Listing Age, and Convertible Bonds

Summary

This stock screen combines three conditions: daily price amplitude above 1%, a listing history longer than one year, and a nonempty name for an outstanding convertible bond. The accompanying rationale treats amplitude as a sign of activity, listing age as a rough stability filter, and the bond association as a way to identify related stocks. The document includes example indicator logic and a Python outline, but the code does not consistently implement every stated filter.

The author warns that requiring a convertible bond can sharply narrow the candidate pool and that bond market swings may affect results. Suggested extensions include adding fundamental measures such as revenue or profit growth and technical measures such as RSI or MACD. No backtest, quantified performance, or evidence that these conditions predict returns is supplied, so the screen is best understood as a proposed selection rule rather than a validated strategy.

Key ideas

• The screen requires price amplitude above 1%, a listing age greater than one year, and an outstanding convertible bond name.
• The stated rationale links amplitude to activity and listing age to company stability.
• Requiring a convertible bond can reduce the number of eligible stocks and exclude other candidates.
• The Python example may not faithfully apply all of the conditions in the written screen.
• The document provides no backtest or measured evidence of profitability.
