Screening Chinese Stocks by Range and a Rising 30-Day Average

Summary

The document outlines a Chinese stock screen combining daily price range with a rising 30-day moving average. Its stated conditions select shares whose high-to-low movement exceeds one percent, whose observation date falls in 2021, and whose 30-day average close is higher than the previous day’s value. The accompanying explanation treats a larger range as a sign of greater volatility and the rising average as evidence of a favorable recent trend.

The post gives formula and Python examples, but their implementations are not fully consistent: the Python example adds a separate close-to-open filter, and its range denominator differs from the formula’s. It offers no backtest or performance evidence. The post cautions that the screen is focused on short-term price action and may be hurt by a broad market decline; it suggests adding fundamental and technical filters, but does not validate those changes.

Key ideas

• The proposed screen combines a daily range threshold with an upward-moving 30-day average.
• The stated date filter restricts the candidates to observations from 2021.
• The Python example includes extra price-change conditions and uses a different range denominator than the formula.
• The post gives no results and warns that short-term signals can be overwhelmed by broader market weakness.
