“Markets don’t crash from all-time highs.”
This old saying is making the rounds again. Why?
The Dow just closed at an all-time high for the 8th consecutive trading day and 34th time in 2017.
That’s a lot of all-time highs, and it comes after the 122 all-time highs in 2013-2016. We haven’t seen this many all-time high in consecutive years since the 1990’s.
Naturally, investors are feeling pretty good, with one prominent strategist proclaiming today that the bull market could “continue forever.”
Interesting, but what does the saying “markets don’t crash from all-time highs” actually mean? And why do people say it?
It’s supposed to imply that buying all-time highs is safer than buying on any other random day. That because tops are said to take time to build, so there will be plenty of time to “stop dancing” before the music stops. It also implies that the largest declines do not immediately follow all-time highs, because volatility tends to be lower on all-time high days than your average day. As volatility exhibits “clustering,” Benoit Mandelbrot observed that “large changes tend to be followed by large changes, and small changes tend to be followed by small changes.”
Are these assumptions supported by the data? Let’s find out…
First, we need to reaffirm that there is nothing inherently bearish about all-time highs. I’ve covered this many times in the past few years with the simple conclusion that “all-time highs tend to be followed by more all-time highs.”
That’s because, on average, forward returns are positive after all-time highs, meaning more all-time highs. The positive forward returns also happen to be a feature of any other random day, though marginally lower than all-time high days.
Note: all data herein are price returns only, not including dividends.
As for the percentage of positive returns, here too we find a likelihood of further gains, with a small edge to all-time highs in periods less than a year.
What about the risk of loss? An all-time high does not seem to preclude large future losses.
However, the largest losses following all-time highs pale in comparison to other days. Why is that? Because record highs tend to occur in periods of lower volatility. Since 1900, the Dow’s volatility on all-time high days was less than half of its average on all days.
It often takes some time for the market to transition from a period of lower volatility (where declines are small) to a period of higher volatility (where declines are large). Hence the saying: “markets don’t crash from all-time highs.”
But “some time” does not necessarily mean a long time. In fact, the worst crashes in the last 100 years, 1929 and 1987, both occurred within two months of an all-time high…
Crashes get all of the attention, but most bear markets are not like 1929 or 1987.
On July 17, 1998, the Dow hit an all-time high. By, the end of August, it had fallen 20%.
The point of this exercise is not to say that the all-time high on August 4, 2017 will join the lexicon of notable peaks, but to understand that it could. There’s nothing magical about an all-time high that prevents large declines from occurring. Indeed, by definition, every bear market in history was preceded by an all-time high.
While volatility clustering makes an imminent “crash” less likely, the environment can change quite rapidly, as we saw in 1929 and 1987. As Nassim Taleb has said, “don’t confuse a lack of volatility with stability, ever.” An all-time high is not without risk.
But the fact remains: stocks tend to go up on average, and as such new all-time highs tend to be followed by more all-time highs. That is as true today as it was on September 3, 1929, January 11, 1973, January 14, 2000, and October 9, 2007. Unfortunately, no one rang a bell at these all-time high tops, alerting you that there would be no new highs for years to come.
Unless this bull market goes on forever, the same will be true today. There will be another large correction. And it will start with an all-time high that looks and feels innocuous. No bell will be rung.
