U.S. equity markets are entering a period in which the valuation difference between technology-oriented companies and traditionally defensive sectors has become unusually large. The attached analysis from Topdown Charts and LSEG shows TMT stocks trading at a relative valuation 115% above the S&P 500, while healthcare, utilities and consumer staples are positioned at approximately a 35% discount, highlighting how strongly capital has concentrated around technology and AI-related growth.

Technology’s Valuation Premium Has Expanded Sharply

The chart shows the relative valuation of the Technology, Media and Telecom sector climbing dramatically since the early 2020s. By the latest observation, the TMT measure had reached roughly 115% relative to the S&P 500, a level the source identifies as the highest since the period surrounding the 2000 dot-com bubble.

The comparison is important, but it does not mean today’s market has the same underlying fundamentals as the late-1990s technology boom. Many of today’s largest technology companies generate substantial revenue, cash flow and profits, while the current investment cycle is being supported by significant spending on artificial intelligence, cloud computing, semiconductors and data-center infrastructure. Reuters reported in September that technology and AI-linked shares were again driving major U.S. indexes toward record levels, with the Nasdaq reaching a record close and semiconductor stocks leading the advance.

Defensive Sectors Are Moving in the Opposite Direction

At the other end of the chart, defensive sectors have experienced a prolonged decline in relative valuation. Healthcare, utilities and consumer staples are shown at approximately 35% below the S&P 500 on the source’s relative valuation measure, close to the lowest levels displayed in the historical series.

The divergence does not necessarily mean the underlying businesses have deteriorated by the same magnitude. Sector valuations are influenced by expected earnings growth, interest rates, capital flows and the opportunity cost of holding slower-growing companies when investors are placing a premium on businesses exposed to structural growth themes. Recent research from State Street similarly describes the market as being dominated by the AI infrastructure and mega-cap technology trade, while noting that sector participation could broaden if economic and earnings conditions become more supportive.

At the same time, traditional defensive sectors are not uniformly inexpensive on every measure. For example, BMO’s September sector analysis noted that utilities were trading at a 16.6 times forward P/E multiple, while healthcare had reached 18.8 times, illustrating why a relative discount to the broader market should not automatically be interpreted as an absolute valuation measure.

What Could Close the Valuation Gap?

A valuation divergence of this magnitude can adjust through several mechanisms. Technology valuations could decline if earnings growth fails to justify elevated expectations, while defensive sectors could re-rate if investors begin to place greater value on stable earnings and cash flows. Alternatively, the gap could narrow gradually if technology earnings continue expanding rapidly while defensive-sector earnings recover without requiring a large change in relative multiples.

The current market provides evidence that the technology premium is still being supported by expectations around AI investment and earnings. Yet market breadth has also become an important consideration. Recent analysis from MarketWatch noted that technology has been leading the latest S&P 500 advance while several other sectors have lagged, raising questions about how broadly supported the market’s gains are.

For global investors, including those in Israel with exposure to U.S. equities, the key issue is therefore not simply whether technology is expensive or defensive sectors are cheap. The more important variables are earnings growth, valuation multiples, interest rates and the sustainability of AI-related capital expenditure. If technology earnings continue to expand at a pace that supports current valuations, the premium could persist; if earnings expectations moderate or capital rotates toward other sectors, the historical valuation gap could become an increasingly important feature of U.S. equity markets. The next earnings season and the trajectory of Treasury yields will provide important evidence on which scenario is developing.
