Screening Stocks by Amplitude, Turnover, and Convertible-Bond Listing

Summary

This stock screen requires price amplitude above one, prior-day actual turnover between three and twenty-eight percent, and a nonempty name for an outstanding convertible bond. The article presents these conditions as filters for price movement, trading activity, and companies with convertible-bond financing, along with illustrative indicator and Python screening logic.

The post does not provide backtest results or evidence that the filters improve returns. It acknowledges that the approach focuses on technical and trading-activity measures without assessing company fundamentals, and that convertible-bond volatility and conversion risk can contribute to losses. It suggests adding financial and industry measures and screening bond issuers for credit quality. Some descriptions of turnover and bond status are not fully reconciled with the sample logic, so the examples do not establish a tested, precise implementation.

Key ideas

• The screen combines an amplitude threshold, a prior-day turnover range, and the presence of an outstanding convertible bond.
• The article frames turnover as a measure of trading activity and bond status as information about financing.
• It does not present performance testing or evidence of profitability.
• The method omits company fundamentals and carries convertible-bond and market volatility risks.
• The article suggests adding financial, industry, and issuer credit-quality filters.
