Screening Small Shanghai-Listed Stocks with Converging Moving Averages

Summary

This note proposes screening Shanghai-listed stocks with market capitalization below 10 billion yuan and no reported losses, then requiring five moving averages to converge. The listed windows are 5, 10, 20, 30, and 60 days. The author interprets the overlap as a sign of relatively stable prices that could precede an upward move, and further suggests favoring stocks with lower price volatility.

The discussion acknowledges that the chosen periods may return too many or too few stocks and that volatile prices can make the signal unreliable. It suggests adding a longer moving average or other indicators such as MACD and RSI. Python examples are included, but their conditions do not reliably implement the stated convergence test: several comparisons are contradictory or compare arrays in ways unsuitable for a single screening decision. No historical performance evidence is provided, so the proposed signal and code require careful validation before use.

Key ideas

• The proposed screen combines a market-cap ceiling, no-loss condition, and Shanghai listing prefix.
• It looks for convergence among 5-, 10-, 20-, 30-, and 60-day moving averages.
• The author treats convergence as a possible sign of price stability and a potential precursor to gains.
• The sample code does not cleanly implement the described rule, and no backtest results are reported.
