One of the ways to determine if the stock market is in a long-term overbought or oversold area is to chart the NYSE Bullish Percent Index which is shown in the chart below. The BPNYA measures the percent of stocks that are on point & figure buy signals. The two key numbers on the chart are 30 and 70. Readings under 30 show the market in a major oversold condition. Readings over 70 show a major overbought condition. The chart shows that the index traded over 70 three times since the start of 2004. A more dangerous signal is given when the line drops back under 70. That's a sign that the overbought market is starting to weaken. I point this out because the BPNYA has just fallen back below 70 (see red arrow).
