Screening Stocks by Daily Amplitude, Convertible Bonds, and the 30-Day Average

Summary

This stock screen combines daily price amplitude of at least 1%, a nonempty outstanding convertible-bond name, and a closing price above its 30-day moving average. The document presents the bond condition as a way to consider financing or credit context and the moving average condition as a trend filter. It includes formula and Python examples, but gives no backtest results or evidence of trading performance.

The author notes that the conditions may be too narrow and may overlook broader company fundamentals, which can result in weak selections or short-lived interest. The post suggests adding financial and valuation measures and adjusting the filters. The examples also have implementation limitations: the prose describes the 30-day average as rising, while the formula checks price relative to that average, and the Python example references a moving average field without showing its calculation. The rules therefore need clarification and validation before use.
