But before we look at the indicator, let’s discuss what it represents. To measure capitulation selling in individual stocks, I use my proprietary Catapult System. To develop it, I conducted many studies focused on identifying capitulation selling situations. In doing so, I managed to discover a few key characteristics that I used to locate likely reversal areas. A core requirement is that an existing trend sees a strong downward acceleration. This is the essence of the Catapult System.
The CBI is basically just a count of the number of open catapult triggers among S&P 100 stocks. My basic finding has been that high CBI readings, which have occurred during market sell-offs, have often been followed by strong reversals. Basically, the more major individual stocks you have suggesting that selling has become too extreme, the more likely a broad market reversal becomes.
You can see the CBI in the bottom panel of the following daily chart of the S&P 500 Index. Since I generally trade vehicles based on the S&P 500, I find the SPX can replace the S&P 100 for analytical purposes.
Since 1995, the CBI has reached 10 or higher on 35 different occasions, meaning a sizable spike occurs once every 7-8 months. But the January 2016 sell-off failed to generate a large spike, and there has not been a substantial sell-off and spike since then. So we have now gone more than 18 months without the CBI reaching 10. Since 1996, there has been only one other instance when the market has gone this long without a capitulation spike: April 2005 to February 2007, a span of 22 months. Then, the bear market hit in late 2007, and there were five spikes over 10 between November 2007 and October 2008.
The following chart shows the CBI since 1995 to provide a historical perspective.
I am not suggesting the next bear market is around the corner. I am suggesting we have experienced a very long period of low volatility. According to the CBI, we are now quite overdue for some type of volatility event, if not something more substantial.
From a seasonal pattern standpoint, the market is getting ready to enter the “worst six months” of the year: May through October. We are also in the first year of a new presidency, and that has often been accompanied by volatile markets. So I would caution traders not to get too complacent. Volatility has been absent for a long time, and I suspect it will not be too long before it returns. Of course, when it does return, I’ll be looking to the CBI to provide clues of selling exhaustion to help me time market entries.
