JPMorgan analyst Steve Tusa thinks grid tech stocks are still a good target despite the sector gaining 30% this year. He says any pullback is a buying opportunity. The demand isn't just from AI data centers, but also general electrification and fixing aging grids. Vertiv is up 60% and trading at a premium, but they think the growth supports the valuation. SolarEdge and Willdan Group have also seen big gains. Global grid spending is expected to go up 16% this year. The sector is currently trading at 21x forward earnings, which is cheaper than the Nasdaq 100. Hedge funds are net long, though some investors warn that valuations are getting high and utility regulations could slow things down.
