Screening Stocks by Rising 30-Day Average, Positive Returns, and Trading Volume

Summary

This stock selection approach ranks by trading volume, then requires a positive return and an upward-sloping 30-day moving average. The article interprets higher volume as greater market attention, positive returns as evidence of recent price strength, and the rising average as confirmation of a longer-term upward trend. It describes the combination as a way to select stocks with both activity and price direction.

The document provides no backtest, measured results, or evidence that the three filters improve returns. It notes that volume alone omits valuation and other company characteristics, positive returns do not remove downside risk, and a rising 30-day average can coexist with short-term pullbacks. Its proposed refinements include evaluating valuation and resilience to declines, but it gives no operational definitions for those additions. The code reference is incomplete, so implementation details and portfolio rules cannot be assessed.

Key ideas

• The screen prioritizes stocks by trading volume, requires positive returns, and selects an upward 30-day moving average.
• The article treats volume as a proxy for market attention and the moving average as a trend filter.
• The filters do not account for valuation, and positive past returns do not prevent losses.
• Short-term reversals can occur even when the 30-day average is rising.
• No empirical results or complete implementation are supplied.
