The uptrend still underway was foretold by crude oil prices 10 years ago, as this week’s chart illustrates. This leading indication is one of the most fun insights I have uncovered in 22 years of newsletter writing. I like to get the answers ahead of time, and often those answers are imperfect. But it is still a compelling insight about the stock market.
I first noticed this when looking at a long-term chart of crude oil prices, using data compiled by the Foundation for the Study of Cycles. I noticed that the chart pattern looked familiar, and it resembled that of the stock market. Putting them together on one chart revealed that my observation was correct, but that the movements of crude oil prices seemed to be leading those of the DJIA. A bit of tinkering showed that a 10-year leading indication made for the best fit.
That insight deserves a moment of contemplation. The chart reveals that crude oil prices seem to know 10 years in advance what the DJIA is going to do. The correlation is not perfect, but it is darned good. How could the crude oil market know in advance what the stock market is going to do?
That is a fascinating but irrelevant question. At some point, where there is enough data, one can let go of the “why” and start accepting the “is”. The leading indication from crude oil prices has only been “working” for the entire history of both the DJIA and crude oil prices. It has not worked perfectly, but it has still worked. For most rational people, 120+ years of data should be seen as enough to validate an hypothesis, although I recognize that for others, this is not enough. Perhaps they need 125+ years.
Here is a chart showing the same relationship, zoomed in on the last few decades:
It lets us see more easily that the uptrend since the 2009 low is just the echo of a similar run-up in oil prices a decade earlier. Oil peaked in June 2008, and so adding 10 years to that date gives us June 2018, plus or minus a few months. When we get to the 10-year echo point of crude oil’s June 2008 top, the stock market should start to see a serious downturn. I have no doubt that President Trump will earn the blame for that downturn, just as he has been getting the credit for the post-election rally. Neither instance of credit/blame is deserved, but that does not stop the media from applying them.
The message from crude oil prices is that the stock market should continue to run upward into mid-2018, and then fall hard. The risk in this hypothesis is that the 2008 commodity bubble collapse might be another exogenous event, like the 1990 Iraq War, or the 1979 Iranian revolution, and that the stock market will ignore this message. If so, then the magnitude of such a stock market price response may be less than indicated. But if oil’s 2008 top was a real market event, then we have some excitement ahead, just before the mid-term elections in November 2018. The stock market should recover nicely from whatever excitement that might be, but that won’t stop the financial media and most investors from blaming President Trump for whatever happens.
