Convensional wisdom suggests that a breakout (Bollinger Band or price channel) should be accompanied by higher-than-average volume. I'm wondering whether this is true? Recently I've noticed several instances where breakouts accompanied by lower volume seem to do better. It's as though the stock is suggesting that it can perform well despite lack-luster participation. Since yesterday (2/11) was rather enthusiastic, this might not be the best example. However, looking at a chart of HNZ, the close (2/11) is above somewhat constricted Bollinger bands and the volume is poor at best. I won't be taking a position in HNZ, but it will be interesting to see how it performs in this situation. Any thoughts?
