Using the Bullish-Bearish Indicator to Spot a Potential Market Bottom or Top

The chart below compares the S&P 500 versus the % difference between the Bullish and Bearish Investment Advisors since 1998. As you can see when the % difference between the Bullish and Bearish Investment Advisors is >30% the S&P 500 has generally made a top and then reversed strongly to the downside. Some examples include last Summer (point A), the early part of 2001 (point B), the Spring of 2000 (point C), the early part of 2000 (point D), the Summer of 1999 (point E) and even further back in the Summer of 1998 (point F). Recently the % difference between the % of Bullish and Bearish Advisors reached near 30% again in January (point G) which was a warning sign that the S&P 500 was likely nearing a top after rallying strongly for three months.
