Big Tech is no longer why the stock market looks expensive

Good morning, investors. Phil here, writing to you from Manhattan.

It surprises me how many investors I speak with still believe AI is an outright bubble, or that dot-com comparisons continue to hold weight.

A year ago, you could have organized the data in a way that supported that view, but it’s become dramatically harder to defend over the last six months.

The numbers tell the story.

Rotating valuations

You can’t blame the Magnificent 7 for a pricey stock market anymore.

For years, investors pointed to Big Tech as the reason for the S&P 500’s premium valuation, but the data now tell a different story.

As it turns out, technology is just one of two sectors — alongside real estate — trading below historical norms.

According to DataTrek Research, all other S&P 500 sectors remain above their five-year average valuation, with the benchmark itself trading at a 6% premium against its recent history.

Technology, meanwhile, currently hovers at a 9.3% discount against its last five years.

In other words, the market’s most frothy valuations have spread well beyond Silicon Valley.

The sector that takes the most criticism for driving froth and bubbles is actually cheaper than the rest of the market.

Elevated multiples have instead rotated elsewhere.

Industrials, communications services, consumer discretionary and consumer staples all trade above their five-year averages, DataTrek’s report shows.

Commodity sectors like energy and materials, too, command richer valuations than just a few years ago.

The wrinkle here is that even as valuations remain elevated, analysts have started to trim earnings expectations for the start of 2026.

Revenue forecasts, though, have actually climbed across most sectors.

That combination implies companies anticipate steady demand but rising costs, which could ultimately compress profit margins.

To put it plainly, the market — even with cheap Big Tech — is still relatively expensive even as near-term expectations deteriorate.
