Best utility stocks

Utilities (electricity, water, gas) are regulated, stable businesses known for their dividends. Their big challenge today is funding huge investments —grids and renewables— in a high-interest-rate environment that makes their heavy debt costlier.

This ranking sorts by fundamental quality, not by whether a stock is cheap or expensive: an excellent company can be expensive. To find the fair price, enter its quote in the analyzer. The scores recompute on their own with each new SEC filing.
