A Bullish Percent Index measures the percentage of stocks within a particular group that are on Point & Figure buy signals. A stock is either on a P&F sell signal or a P&F buy signal, there is no gray area here. A P&F sell signal is a Double Bottom Breakdown, which occurs when the current O-Column moves below the low of the prior O-Column. A P&F buy signal is a Double Top Breakout, which occurs when the current X-Column moves above the high of the prior X-Column. The first chart shows Illumina (ILMN) with a Double Top Breakout and the second chart shows Mattel (MAT) with a Double Bottom Breakdown.
The next chart shows the Bullish Percent Index for the Nasdaq 100 ($BPNDX) at 74%, which means 74 of the 100 stocks are on P&F buy signals. This also implies that 26% are on P&F sell signals. In its most basic form, the Bullish Percent Index favors the bulls when above 50% and the bears when below 50%. Chartists can also look for divergences and overbought/oversold readings for signals.
