Investor optimism around a proposed Trump administration ban on new Chinese-made solar inverters on cybersecurity grounds has pushed SolarEdge Technologies (SEDG) back into focus as funds reassess potential market share shifts.

SolarEdge Technologies has seen sharp swings, with the share price down 6.46% over the past day and 17.08% over the past month, yet up 16.17% over 90 days and 67.03% year to date. The 1 year total shareholder return of 90.20% contrasts with much weaker 3 and 5 year total shareholder returns, suggesting strong recent momentum after a long period of weakness.

After such a strong rebound in SolarEdge Technologies, mixed long term returns and recent policy optimism leave a key question for investors: is the stock still trading below what its fundamentals justify, or has the market already priced in future growth?

Most Popular Narrative: 20.7% Overvalued

At a last close of $52.38 versus a narrative fair value of $43.38, the current SolarEdge Technologies share price sits well above that central estimate, which is built on detailed assumptions about future growth, profitability and discount rates.

The rally in SolarEdge's stock appears to be pricing in robust future revenue growth driven by U.S. policy support (extension of manufacturing and storage credits). However, risks are rising as the elimination of the 25D residential solar tax credit is expected to cause a substantial drop in U.S. residential demand in 2026, only partially offset by third-party owned (TPO) shifts, potentially constraining topline growth.

Want to see what sits behind that fair value cut of the current price? The narrative leans on a specific growth path, margin rebuild and earnings multiple that might surprise you.

Result: Fair Value of $43.38 (OVERVALUED)

However, stronger than expected battery storage adoption or sustained U.S. manufacturing tax credits could support SolarEdge Technologies margins and earnings more than this overvalued narrative allows for.

Another View: What SolarEdge Technologies' Sales Multiple Is Saying

While the narrative fair value suggests SolarEdge Technologies is overvalued, the simple P/S ratio tells a different story. At 2.5x sales, the stock trades far below the US Semiconductor industry at 8.4x and a peer average of 12.8x, and even below a 3.2x fair ratio that the market could move toward. For investors, that gap points to either valuation risk in the sector or potential upside in SolarEdge if its fundamentals line up with those sales expectations. Which side of that debate do you find more convincing?
