The S&P 500 Is Becoming a Tech Index in Disguise -- But That May Not Be the Risk Investors Think

The S&P 500 is increasingly trading like a technology index despite its broader label, driven largely by the artificial intelligence boom, the article says. Technology, Media and Telecom companies make up nearly half of the index’s market capitalization—about 9 percentage points higher than the dot-com bubble peak and roughly 20 points above late-1960s levels. Information Technology accounts for about 35% to 38%, while Communication Services contributes another 10% to 11%, and the reach is expanded further by technology-led firms classified elsewhere, including Amazon and Tesla. The report argues that concentration risk is rising because gains and volatility are increasingly dependent on a small group of mega-cap AI beneficiaries. It also notes that spending on AI has surged since 2019, with tech capital expenditures up nearly 876% versus 62% for the rest of the index. Deutsche Bank Research said most companies outside Big Tech appear healthy and not excessively valued, with growing cash holdings and limited net borrowing.
