MGE Energy (MGEE) was removed from several Russell growth indexes on 27 June 2026, a change that can affect index-linked flows and short term trading interest in the stock.

The index removals come after a period where MGE Energy’s share price has picked up, with a 14.74% 1 month share price return and a 7.38% year to date share price return, even though the 1 year total shareholder return is down 4.25%.

With MGE Energy trading at $84.23, a value score of 1 and an intrinsic value estimate that sits well below the current share price, the key question is whether the recent strength leaves upside on the table or if the market is already pricing in future growth.

Price-to-Earnings of 23.6x: Is it justified?

On a P/E of 23.6x, MGE Energy looks expensive relative to both its own fair-value benchmark and the wider US electric utilities industry, even with the recent share price strength to $84.23.

The P/E ratio compares what you pay today for each dollar of current earnings. For a regulated utility like MGE Energy, it helps gauge how much the market is paying for what is often a steadier earnings profile.

For MGE Energy, the current 23.6x P/E sits above the estimated fair P/E of 17.4x. This points to a valuation level the market could potentially move back toward if expectations cool. At the same time, the stock trades on a higher P/E than the US Electric Utilities industry average of 22x, suggesting investors are attaching a premium to its earnings relative to peers.

Result: Price-to-Earnings of 23.6x (OVERVALUED)

However, MGE Energy’s low value score and current share price, which sits above both intrinsic estimates and analyst targets, could leave the stock vulnerable if sentiment cools.
