Major Moves
There are a lot of theories about what contributed to the market’s reversal this week. Some analysts believe this could be the doing big pension fund managers who are having to rush at the end of the year to balance their portfolios. Reassurances from the White House that the Treasury Secretary, Steven Mnuchin, and Federal Reserve chair, Jerome Powell, are both safe in their jobs might have also driven prices higher.
I still believe that the underlying fundamentals, which are very strong from an earnings perspective, is the most likely driver of higher prices in the near term. However, traders should be careful about drawing conclusions in either direction during the week between Christmas and New Year’s Day. Volume tends to be light and temporary factors can have a greater than expected impact on the major indices.
From a technical perspective, there is an interesting pattern beginning to form on the VIX index. A study published by the CMT Association a few years ago showed that when the VIX reached an extreme and then failed to repeat that extreme within five trading sessions there was an unusually high probability of a continuation to the upside.
The extreme used in the study was for the VIX to close beyond a 10-period Bollinger Band price channel, but then failed to close above that price channel again within five trading sessions. In the following chart, I have compared the S&P 500 (top) with the VIX (represented by line chart on the bottom) and I’ve included a Bollinger Band study to illustrate the first half of the signal that has emerged so far.
While it’s not perfect, this trading signal has had a good track record over the last several years. The subsequent rallies are usually big and short-term. For example, the same signal was triggered earlier this year on February 9th, which I’ve highlighted on the chart. For the signal to complete successfully this time we would need to see the VIX spike up a little and drop again very quickly next week.
Even if the pattern doesn’t play out this time, I doubt we’ve seen the last of the market volatility, and there may be another opportunity for a signal like this early in the first quarter of 2019.
