The stock market is hitting record levels on all fronts.
The S&P 500 (SNPINDEX: ^GSPC), Dow Jones Industrial Average (DJINDICES: ^DJI), and Nasdaq Composite (NASDAQINDEX: ^IXIC) have all hit record highs this year, extending a bull market that’s been nearly four years in the making. If these gains hold, 2026 will mark the fourth consecutive year of double-digit returns, extending one of the strongest multi-year runs in decades. That’s a record worth celebrating.
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 »
And yet there’s another record the market is approaching that Wall Street might not be so eager to break.
The CAPE ratio is closing in on the dot-com era record
That record is the S&P 500’s Shiller CAPE ratio, a measure of how expensive the stock market is relative to its earnings. In simple terms, the CAPE tells us how much investors are paying for every dollar of average inflation-adjusted earnings that the S&P 500 has produced over the last decade.
Over roughly 155 years of market history, the CAPE has averaged about 17. Today, it sits at roughly 41. This is only the second distinct period in market history in which the ratio has entered 40-plus territory; indeed, we are now only 3 points away from matching the ratio’s all-time high of 44.
When the CAPE peaked around 44, it was late 1999, and the dot-com boom was coming to a close. Many dot-com companies were priced at extraordinary valuations, and the sheer number that subsequently went bankrupt tells you how far prices had detached from fundamentals.
Today’s market has similarities to the dot-com era — the excitement over a new technology, the enormous amounts of capital being poured into it, the fear of missing out. And yet the two are not synonymous. Many of the dot-com companies had zero profits and little revenue, whereas the companies most responsible for today’s rally are enormous, highly profitable enterprises. Nvidia, in other words, is no Pets.com.
At the same time, we shouldn’t ignore a high CAPE ratio; indeed, few valuation metrics are better at putting today’s market into historical perspective. Even great companies can become more disappointing if their high valuations leave little room for earnings to fall short of expectations. Today’s market is getting uncomfortably close to that point.
