Power Integrations (POWI) Stock Looks Overvalued After A 59% Five Year Fall

Power Integrations has seen its share price fall sharply in recent weeks, which puts fresh focus on whether the current valuation lines up with what the business is earning today. With the stock now some distance from its past highs, the key issue is how much of the recent earnings power the market is really paying for.

• Over the past 5 years the stock has fallen 59.3%, which raises questions about how investors should think about its earnings profile after such a long reset.
• Recent growth in demand for gallium nitride products and a higher dividend can support a view that future earnings and cash generation may look different from the past, which matters when you weigh the current share price against its profit base.
• There is a second opinion on Power Integrations worth weighing. See what analysts think Power Integrations's shares could be worth.

Is Power Integrations Getting Expensive on Earnings?

The P/E ratio fits Power Integrations because earnings are a key driver of how investors frame value for a profitable chip designer. The stock trades on a P/E of 48.5x, which is well above the Semiconductor sector average of 36.4x and ahead of the peer group on 26.6x. This means each dollar of current earnings at Power Integrations is priced more highly by the market than earnings at many comparable chip makers.

The Fair Ratio, which reflects what investors might typically pay given Power Integrations' size, economics and risk profile, comes out below the current market multiple, so the shares screen as overvalued on this measure. Despite the positive reaction to Q3 2026 GaN demand and the higher dividend, the valuation already assigns a premium to those trends compared with many sector alternatives. That gap is what you need to weigh when deciding whether the current P/E still leaves enough room for your own return expectations. Explore the numbers behind Power Integrations's P/E valuation.
