For the First Time in Over 155 Years, the Stock Market May Be Headed Here — and It’s Not Good News for Investors


Over the past decade, the S&P 500 (SNPINDEX: ^GSPC) has delivered a phenomenal total return of around 250%, compounding at roughly 13.4% annually. Over the last year alone, the stock market, driven by developments in artificial intelligence (AI), has surged almost 23%, with its ferocity drawing comparison to some of the strongest bull runs in market history.

That’s less reassuring than it sounds.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »

A market that’s gone too far, too fast

The stock market is currently trading near its most expensive valuation ever. That’s not an exaggeration. The last time the market was this richly valued, it was in the months preceding one of the ugliest crashes Wall Street has ever seen — the dot-com debacle of the early 2000s.

What do I mean by “richly valued”? In simplest terms, today’s investors are paying more for each dollar of corporate earnings than at almost any point in history. One way to measure that is the Shiller CAPE ratio, which compares the current price of an index (like the S&P 500) to inflation-adjusted earnings over the previous 10 years.

Thanks to some clever statistical work, the CAPE ratio, introduced in the late 1980s, has been backtracked to 1871, giving us 155 years of historical context. Over that time, CAPE has averaged about 17. Take a gander at where it is now.

Is a stock market crash imminent?

Looking at the chart, we can see that the CAPE ratio has spiked only twice. The first came just before the Great Depression in the late 1920s, and the second came in the late-90s run-up to the dot-com crash.

Does that mean a stock market crash is coming? Not necessarily. Stock market metrics like the CAPE ratio can help us compare valuation levels, but they can’t predict the future. If history is a reliable guide, periods like this one often precede sharp reversals, yet that doesn’t mean the stock market will fall like it did in 2000 again.

The market often rewards investors who stay put long-term rather than try to buy and sell at the “right” time. Look closely at the stocks you’re buying, as strong fundamentals will outlast short-term trends and hype.
