Screening Stocks by Intraday Amplitude, Limit-Down Pricing, and Convertible Bonds

Summary

The proposed stock screen combines three conditions: amplitude above a stated threshold, a prior-day 9:15 matching price at the limit-down level, and an associated unredeemed convertible bond with a nonempty short name. It then selects a limited number of candidates, with the accompanying example sorting by stock heat. The article provides indicator-style expressions for the amplitude and prior-day price checks, plus a Python sketch that intersects bond-linked company names with stock data.

The post characterizes the setup as involving volatility, market sentiment, and convertible-bond activity, and recommends examining candidates further and diversifying. It offers no backtest, selected-stock history, or measured performance to support the proposed rationale. The Python sketch mixes platform-specific expressions with data fields and sources that may not be available or aligned as shown; the convertible-bond name matching also needs careful verification. The selection conditions alone do not specify trade entries, exits, sizing, or how to handle corporate actions and changing bond status.

Key ideas

• The screen combines an amplitude condition, a prior-day limit-down matching-price condition, and a convertible-bond association.
• The example ranks qualifying stocks by a heat measure and returns a limited number of candidates.
• The post recommends adding broader analysis and diversification to address concentration and market risks.
• No historical performance evidence or complete trade-management rules are provided.
• The code sketch relies on fields and functions that may need adaptation and validation.
