The traditionally defensive sector has never been this cheap relative to the S&P 500, and the reasons tell a bigger story about where capital is flowing.
The S&P 500 Utilities sector has fallen to a record-low relative value ratio of 0.06 against the broader index. Utilities companies have never been this out of favor compared to everything else in the S&P 500.
That 0.06 ratio means for every dollar of value in the broader index, utilities represent just six cents of comparable weight.
How utilities went from darling to doormat #
In 2025, utilities outperformed the S&P 500 during stretches when surging power demand, driven partly by the explosion in data center construction and AI infrastructure, made the sector look like it had real growth potential for the first time in years.
That narrative has since unraveled. Rising Treasury yields in 2026 have been the primary headwind, making the sector’s dividend yields less attractive on a relative basis.
The sector’s forward price-to-earnings ratio currently sits between 17.8 and 18.4 as of late May 2026. Growth-oriented sectors, particularly technology, have been vacuuming up capital as investors bet on economic recovery and AI-driven earnings expansion.
The bigger picture: a capital rotation story #
What makes the current moment different is the magnitude. A 0.06 ratio is uncharted territory. Previous troughs in relative value never reached this level. The sheer dominance of mega-cap tech in the S&P 500’s weighting has compressed the relative value of nearly every other sector, but utilities have been hit particularly hard because they sit at the opposite end of the growth spectrum.
Rising Treasury yields create a double problem for utilities: they increase borrowing costs for capital-intensive utility companies, and they make the sector’s dividend yields less compelling compared to risk-free alternatives.
What this means for investors #
The bull case is straightforward. If Treasury yields decline, utilities would likely see significant inflows from yield-seeking investors, particularly retirees and pension funds. At a record-low relative valuation, the snapback potential is meaningful.
The risk to watch is a sudden shift in the interest rate environment. Any indication that the economic expansion is cooling, or that central banks are preparing to cut rates, would be the most direct catalyst for a utilities rebound. Conversely, if yields continue climbing, the sector could remain pinned at these historically depressed relative levels.
