Chinese Stock Screening with a 250-Day Average and Position Increases

Summary

This stock screen combines two conditions: yesterday’s closing price was above its 250-day moving average, and today’s position-increase ratio exceeded 5%. The document interprets the long-term average as a sign of price strength and support, and the increase in positions as possible evidence of institutional interest. It also proposes adding industry outlook, financial health, and profitability filters.

The article provides a conceptual rationale and illustrative data-handling code, but no backtest, performance figures, or evidence that the conditions predict future returns. It cautions that the screen omits company and industry fundamentals and may be less reliable during volatile markets. The proposed extra filters are suggestions rather than evaluated parts of the original screen.

Key ideas

• The screen requires yesterday’s close to be above the 250-day moving average.
• It also requires today’s position-increase ratio to exceed 5%.
• The article treats these conditions as signs of price strength and possible institutional interest.
• It suggests adding financial, industry, and profitability measures, but does not test them.
