US utility stocks used to trade at an average EV-to-EBITDA (enterprise value to earnings before interest, tax, depreciation, and amortization) valuation multiple of 9.0x. They’re currently trading at an average of 11.0x. Given their PE (price-to-earnings) multiples, US utility stocks appear significantly overvalued. Their five-year historical average PE multiple is ~15.0x, while they’re currently trading at ~19.0x.
Utilities’ current valuations indeed hint at a possible correction. But any recent notable correction in utilities was followed by a strong buying action, bringing the valuations high again.
