Chinese Stock Screening With a Rising 30-Day Average and Amplitude Filter

Summary

This document describes a Chinese equity screening rule combining a rising 30-day moving average, stock amplitude above a stated threshold, and market capitalization above a stated floor. It frames the rising average as a short-term trend filter and suggests adding rolling statistics and fundamental information to reduce reliance on a small set of indicators. It also sketches implementations using a Chinese stock screening platform and Tushare data.

The page offers no backtest results or evidence that the screen predicts returns. Its stated formula and code examples do not fully agree: the title refers to the moving average rising, while one formula compares the close with the 30-day average, and the Python example estimates average direction over a rolling window. Amplitude and capitalization calculations also differ across examples. The article itself notes that a short-term trend can miss longer-term direction, that the filters may not suit every market, and that technical screening alone can overlook company quality. The rule is best understood as a screening concept requiring specification and validation.

Key ideas

• The screen combines stock amplitude, market capitalization, and a 30-day moving-average condition.
• The article proposes adding rolling measures and fundamental data to broaden the selection criteria.
• The displayed formulas and code use inconsistent definitions, so the rules need to be clarified before implementation.
• No performance evidence is provided, and the screen may miss longer-term trends or company-quality risks.
