This valuation signal shows how investors are rethinking tech stocks Brian Sozzi · Executive Editor Mon, August 3, 2026 at 4:44 PM GMT+2 3 min read AMZN GOOG ^GSPC NVDA AAPL Investors are finally realizing there are more companies in the stock market to invest in than Big Tech. How do I know? Look no further than the valuations on the top five largest companies in the world.

Quick analysis: Shares of the dominant tech companies have derated, meaning their valuation multiples have been adjusted downward, driven by a growing investor anxiety about the future returns from AI capital expenditures. The five largest stocks in the US now have price-to-earnings (P/E) ratios only marginally above those of the other 495 stocks in the S&P 500 ( ^GSPC ), Goldman Sachs strategist Peter Oppenheimer pointed out in a new note (see the chart below). The five largest companies by market cap according to Yahoo Finance AlphaSpace data are Nvidia ( NVDA ), Apple ( AAPL ), Alphabet ( GOOG , GOOGL ), Microsoft ( MSFT ), and Amazon ( AMZN ).

These companies have consistently had a premium since 2017. Valuations have come in a lot on tech names. · Goldman Sachs The hyperscaler valuation convergence has been matched by a sharp derating in the relative valuation of software stocks, Oppenheimer said.

The sector's P/E premium globally has fallen to around 20%, a far cry from the near 200% at the start of this century. What's more, performance leadership within the tech space has shifted from software to hardware, with memory and chip stocks seeing explosive demand for compute and a major step-up in earnings growth. Oppenheimer explained, "It also marks a very big change from the dot.

com era. Back then, valuations reached a much greater high, but they came down as stock prices collapsed. This time, prices have adjusted more modestly, but earnings have remained exceptionally strong.

" What else you need to know: Zooming out, tech stocks have struggled to gain traction this summer as investors have begun questioning whether the sector's AI-driven rally has become too stretched after years of outsized gains. The pressure has intensified of late as the largest technology companies, such as Oracle ( ORCL ), Meta ( META ), and Alphabet, continue to commit hundreds of billions of dollars to AI infrastructure, fueling concerns that capital spending is rising faster than the revenue those investments can generate.  Not helping sentiment is that these companies are using debt to fund their lavish spending.

At the same time, semiconductor stocks have come under heavy selling pressure amid profit-taking, weakness in South Korea's chip sector, growing competition from China, and worries that memory chip shortages could weigh on hardware supply chains.   Higher Treasury yields and expectations that interest rates could remain elevated have also reduced investors' appetite for richly valued growth stocks, prompting a rotation into more defensive and cyclical sectors. Story Continues The bottom line: Just because valuations have come in for the five largest companies by market cap, that doesn't make them screaming buys.

The capital expenditures outlook is robust, which could continue to put pressure on free cash flow, a key driver of valuation for any company.
