Stock Trends’ Unusually High Volume (
) indicator flags stocks whose weekly trading volume is at least 200% of their 13-week average. In the October 31 weekly reports, only a small slice of the universe qualifies—making these signals rare and valuable. When high volume coincides with a bullish trend state (or a new Bullish Crossover), it can mark institutional footprints at the start of a multi-week advance.
How to Read the Signals (Quick Refresher)
- Bullish (
): Price is decisively above the 13- and 40-week moving averages. - Weak Bullish (
): Temporary dip below the 13-week average while the long-term uptrend persists; may precede a Bearish Crossover but often reverts back to Bullish. - Bullish Crossover (
): 13-week MA crosses above the 40-week MA—often the start of a major up-leg, especially if volume is high.

- Cross-check trend state: prioritize Bullish and Bullish Crossover names with high volume; track Weak Bullish names for return-to-Bullish entries.
- Layer in Bullish Crossover and Bullish Crossover Predictions filters. A stock that appears in both a crossover list and the high-volume list deserves immediate attention.
- Check Weak Bearish (
) stocks and weekly Picks of the Week reports for High Volume indicators. The Newly Weak Bearish report will also help isolate early reversals. - Check the weekly ST-IM Select stocks report for each exchange for high-volume stocks.

Note on interpretation: Weak Bullish trends often precede Bearish Crossovers, but they also frequently revert back to Bullish. Many recent Weak Bullish names in this dataset have rebounded to (Strong) Bullish—precisely where high-volume confirmation is most informative. Alternatively, Weak Bearish trends often precede Bullish Crossovers (that's why they are a major focus of Stock Trends reports like the Picks of the Week), but they can also revert to (Strong) Bearish.
