A-Share Screen for High Amplitude and Rising Five-Day Averages

Summary

This Chinese stock-screening note proposes selecting non-Star Market shares with daily amplitude above 1 and a rising short-term average pattern. It describes the screen as a way to find volatile stocks showing near-term upward price movement. Its indicator reference expresses the average condition using the close and the prior five-day moving average, and it identifies the excluded market segment by an industry code. The accompanying Python example also filters for positive price-to-earnings ratios and uses historical price data, though these details are not consistently part of the stated final screen.

The note offers no backtest, performance figures, or comparison demonstrating that the filters predict returns. It warns that technical signals may miss company results and industry shifts, and suggests adding fundamental and industry measures or other indicators. The explanation that non-Star Market shares imply greater stability is an unsupported generalization; market segment alone does not establish company quality or investment value. The precise amplitude units and implementation details also need checking before use.

Key ideas

• The screen combines daily amplitude above 1 with a short-term rising-average condition.
• It excludes stocks in the Star Market using an industry-code filter.
• The code example adds a positive price-to-earnings filter that is absent from the final stated rules.
• The note provides no performance evidence and cautions that technical signals omit company and industry factors.
