One smart stock-market analyst thinks this is where we're headed... (gulp)

No one knows what the stock market is going to do, but if you want to get an informed sense of what it might do, it helps to understand what it has done.

And in the perpetual debate about where we're headed next, one mistake that is often made is confining one's observation of market history to recent trends instead of the many generations of market data that are now available.

One analyst who does the latter is John Hussman of the Hussman Funds.

Hussman's reputation has been clobbered of late because he missed the market turn in 2009 and then acted on his more recent concern about an impending crash several years too early. 

As the market has struggled over the past 18 months, however, Hussman's concerns have been partially vindicated.

And those hoping that the recent 15% drop from the peak was just a little bobble in a great new bull market won't like to hear where Hussman thinks we're headed next.

Specifically...

Here's where we are:

And here's where Hussman thinks we're headed next:

That latter chart is a chart of the 1929 crash, one of the most famous in history.

Hussman thinks it also loosely illustrates our likely future.

Hussman's key observation about that chart — and the charts of many other market crashes in history, the most recent two of which he has correctly forecasted in advance (2000 and 2007) -- is that market crashes generally follow the same pattern.

First, in a market in which stocks are highly overvalued (as they are today) and in which investors are increasingly risk-averse (as they are today — see the spreads on interest rates between safe and risky bonds), crashes are much more likely than they are in any other market environment.

Second, crashes do not just happen suddenly -- for years everything's great and then one day the market just falls out of the sky. Rather, crashes develop over many months. And the "crash" itself — the period of massive, near-vertical market losses — generally starts AFTER THE MARKET IS ALREADY DOWN ABOUT 15%.

That's the insight to note in the chart above.

And because one observation is rarely persuasive, here's another Hussman chart, this one showing the crash in 1987. Same pattern. Down about 10%-20% fom the top, some failed recoveries, and then, blam.

And, for good measure, here are charts of the crashes in 2000 and 2007. Same pattern. A general peaking and "rolling over" for many months, followed by a 10%-20% drop, followed by some stabilization and recovery, followed by a mega-crash.

Is that what will happen this time?

No one knows.

But anyone who's feeling comfortable after a strong week in the markets should at least understand that 1) the macro environment most conducive to crashes is still in place (overvaluation + increasing risk aversion) and 2) the way the market is behaving now is exactly the same way it behaved before the biggest crashes in history.

So, neither Hussman, nor I, nor you should be surprised if the market keeps on dropping and doesn't bottom until it's down 50% or more from the peak.

As Hussman noted last week in his usual depressing note, a 50% crash would not even be the worst-case scenario. It would just be a normal correction from valuations we reached in 2015. The "worst-case scenario" would take us down 75%.
