Chinese Stock Screen Using Daily Range, Listing Age, and the 10-Day Average

Summary

The article describes a stock-selection screen that combines three filters: daily high-low range above a threshold, more than a year since listing, and an opening price near the 10-day moving average. It presents the range and listing-age filters as proxies for activity and relative stability, and treats proximity to the average as a way to find stocks with recent market interest. Indicator formulas and a Python example sketch out how the criteria might be applied to daily stock data.

The explanation cautions that these filters alone may not reflect a company’s fundamentals or provide enough technical context. It suggests adding valuation measures or other indicators, but supplies no backtest, performance statistics, benchmark, or risk-adjusted evidence. The example’s implementation and described screening rule do not align perfectly: the rule says the open should be around the average, while the code applies a narrow band around it. The screen is therefore a starting specification rather than a validated strategy.

Key ideas

• The screen combines daily price range, time since listing, and the opening price’s relation to a 10-day average.
• The article treats range and listing age as rough proxies for activity and stability.
• It suggests adding fundamental or technical filters to refine candidate stocks.
• The document provides no backtest evidence, and its code differs somewhat from the stated proximity rule.
