Advanced Energy Industries (AEIS) is back on trader radars after the December 18, 2026, $90 call option showed some of the highest implied volatility in the equity options market today.

The options activity comes after a choppy few months for Advanced Energy Industries, with the share price up 30.42% year to date but down 25.58% over 90 days. At the same time, the 1 year total shareholder return of 114.44% and 5 year total shareholder return of 212.98% point to strong longer term gains even as recent momentum has cooled.

After a 1 year return above 100% and a sharp pullback over the past quarter, Advanced Energy Industries now sits at a crossroads. Is most of the easy upside already in the rearview mirror, or does the current valuation still leave meaningful room ahead?

Most Popular Narrative: 32.5% Undervalued

At a last close of $289.52 versus a narrative fair value of $428.73, Advanced Energy Industries is being framed as materially discounted, with that gap hinging on a very specific growth story.

Sustained expansion in data center and cloud computing infrastructure, especially driven by AI workloads, is fueling robust demand for Advanced Energy's next-generation high-power density solutions; strong design win momentum and customer forecasts suggest revenue growth in this segment will remain above historical averages into 2026 and beyond, providing significant top-line upside.

Want to see what sits behind that AI data center push and the higher fair value? The narrative leans on faster top line growth, wider margins, and a richer future earnings multiple included in its model.

Result: Fair Value of $428.73 (UNDERVALUED)

However, the Advanced Energy Industries story also leans on concentrated hyperscale customers and tariff exposed semiconductor demand, which could quickly test those optimistic growth assumptions.

Another View: What Multiples Say About Advanced Energy Industries

The 32.5% narrative discount for Advanced Energy Industries sits awkwardly alongside how the stock is priced on earnings today. Its P/E of 57.4x is above the US Electronic industry at 30.5x, the peer average at 55.2x, and the fair ratio of 53.2x. That points to a premium that could limit upside if expectations ease. How comfortable are you with paying that kind of earnings multiple?
