How Imminent is the Next Market Crash?

image001This past week I received an article from a client regarding ideas about “wealth preservation” that made some good sense, and offered advice about calculating how much money you need for retirement. But while the premise was sound; that it makes sense to pursue investment strategies that protect your nest egg when your financial needs are already met, a one off comment about the future of the stock market caught my attention.

You can read the article HERE, but the issue I wanted to look at was the not so subtle implication that the US markets were now due for a correction. A serious one. Quoting the Wall Street Journal contributing writer William J. Berstein,

“In March, the current bull market will be six years old. It might run an additional six years—or end in April.”

This isn’t the first time I’ve heard this point before. It isn’t unique and sits on top of many other market predictioner’s tools, but its use of averages gives a veneer of knowledge the writer simply doesn’t possess.

Obviously we would all like to know when a market correction is due, and it would be great to know how to sidestep the kind of volatility that sets our retirement savings back. But despite mountains of data, some of the most sophisticated computers, university professors, mathematicians and portfolio managers have yet to crack any pattern or code that would reveal when a market correction or crash should be expected.

Which is why we still rely on rules of thumb like the one mentioned above. Is the age of a bull market a good indication of when we will have a correction? Probably not as good of one as the writer intends. Counting since 1871, the average duration of a bull market is around 4.5 years, making the current bull run old. But averages are misleading. For instance the bull markets that started in 1975, and 1988 (ending in 1987 and 2000 respectively) lasted for 153 months each, or just shy of 13 years. Those markets are outliers in the history of bull markets, but their inclusion in factoring the average duration of the bull markets extends the average by an additional year. Interestingly if you only count bull markets since the end of the second world war the average length is just over 8 years, but that would only matter if you think our modern economy has significant differences from an economy that relied on sailing vessels and horses.


The fact is that the average age of bull markets is only that, an average. It has little bearing on WHY a bull market comes to an end. There was nothing about the age of the bull market in the 2000s, when people had become convinced of some shaky ideas about internet companies that make no money, that had any bearing on its end. The bull market that ended in 2008 had more to do with some weird ideas people had about lending money to people who couldn’t pay it back than it did with a built in expiration date. Even more importantly, the market correction of 1987 (Black Monday) was an interruption in what was an otherwise quarter century of solid market gains.

Taking stabs at when a market correction will occur by using averages like duration sounds like mathematical and scientific rigour, but actually reveals very little about what drives and stops markets. And a quick survey of the world tells us a great deal more about global financial health and where potential opportunities for investment are than how long we’ve been the beneficiaries of positive market gains.
