A-Share Screening with Weekly Trend, Capital Inflow, and Profitability Filters

Summary

This A-share screening idea combines three conditions: market capitalization below 10 billion yuan, no reported losses, and the weekly price crossing above its 30-week moving average. It also requires the day’s increase in holdings to exceed 5%, which the article treats as a sign of buying interest. The author explains the intended roles of the filters and suggests adding valuation measures and indicators such as MACD or Bollinger Bands. The article provides no backtest, performance figures, or empirical evidence that the conditions predict returns.

The stated risks include reversals in capital flows, pullbacks after a trend signal, and greater volatility among smaller companies. The accompanying sample screening code and proposed final conditions do not cleanly match the original rules, and the code’s treatment of some indicators is questionable. The screen is therefore best read as a basic strategy sketch; it does not establish that the criteria reduce risk or identify undervalued stocks.

Key ideas

• The screen combines a sub-10-billion-yuan market-cap limit and a no-loss requirement with a weekly close crossing above its 30-week moving average.
• It requires the reported daily increase in holdings to exceed 5% as a buying-interest filter.
• The article proposes adding valuation ratios and technical indicators, but supplies no evidence that these additions improve results.
• Small-company volatility, short-term pullbacks, and changing fund flows can undermine the signals.
