A-Share Screening with Price Amplitude, Convertible Bonds, and MACD

Summary

The document describes an A-share stock screen using three conditions: daily price amplitude above one percent, a nonempty name for an outstanding convertible bond, and daily MACD above zero. Its rationale associates amplitude with price movement, the bond condition with a company characteristic, and positive MACD with upward price trend. It provides sample formula and Python material, but the code’s implementation does not consistently match the stated screen: for example, it calculates an index MACD and adds other filters that are not part of the headline logic.

The author cautions that technical conditions alone can select weak companies and that MACD may react to short-term market swings. Suggested extensions include valuation and earnings measures and checking trends over longer horizons. No historical performance, benchmark comparison, or evidence of profitability is presented, and the specific conditions should therefore be read as a screening example rather than a validated strategy.

Key ideas

• The stated screen requires daily amplitude above one percent, an outstanding convertible-bond name, and daily MACD above zero.
• The document interprets amplitude as a volatility signal and positive MACD as an upward trend signal.
• The sample Python implementation includes additional filters and differs from parts of the stated logic.
• The author identifies weak-company selection and sensitivity to short-term moves as risks.
• Fundamental measures and longer trend windows are suggested as possible additions.
