Stock Screening with a Rising 30-Day Average and Relative Volume

Summary

This Chinese equities screening note combines three technical filters: rank stocks by volume ratio and retain the top 100, look for a Bollinger Band condition described as the middle band crossing above the lower band, and require the 30-day moving average to be rising. It presents these as signs of stronger money flow, a possible price turn, and an upward trend, respectively.

The article recommends supplementing the filters with turnover and trading volume, MACD or RSI, and valuation measures such as PE and PB. It also identifies the limits of relying on each signal alone: volume flow does not capture fundamentals, a band configuration does not capture market sentiment, and a rising average does not capture industry conditions. These are qualitative explanations rather than empirical evidence; the note gives no backtest, performance figures, or detailed operational rules for combining the filters.

Key ideas

• The screen ranks stocks by volume ratio and selects the top 100.
• It adds a Bollinger Band crossover condition and a rising 30-day moving average.
• The author suggests combining the signals with trading activity, momentum indicators, and valuation measures.
• Each indicator captures only part of the investment picture, and the note reports no performance test.
