The $BPNDX is, as Dorsey says, a "souless barometer." What the future will bring is anybody's guess, but the Bullish Percentage is a very reliable breadth indicator and tells us which "team should be on the field" (as I am watching the Dolphins score again against the Patriots!); offense or defense. Currently, it should be offense, so Dorsey would advise trading long in sectors that have relative strength and in stocks that have relative strength within the sector.
