Bel Fuse (NASDAQ: BELFB) has rallied about 57% so far this year, powered by surging demand for the power conversion, circuit protection and connectivity components it supplies to data centers. Every single analyst covering the stock rates it a Buy — six out of six — with an average price target near $316, according to data compiled by the firm. Citi analyst Asiya Merchant, who has an 82% success rate on her picks, initiated coverage on July 13 with a Buy rating and a $325 target. Bank of America followed with its own Buy initiation the next day.
Why the data-center boom matters
Bel Fuse’s data segment grew roughly 14% last quarter, and its backlog jumped 21%. Those numbers reflect a broader industry trend: Google has guided its 2026 data-center capital spending toward $190 billion, and grid operator PJM projects 32 gigawatts of new peak demand through 2030, almost all of it from data centers. The company’s components — used in power conversion, circuit protection and connectivity — are essential to building and running those facilities.
Valuation and volatility
At a price-to-earnings ratio near 55, Bel Fuse isn’t cheap. Options implied volatility sits in the 98th percentile of its past year, meaning traders expect big swings. That could cut either way, but the analyst consensus suggests the upside is still there. The stock is also included in the VistaShares Electrification Supercycle ETF, alongside companies like Eaton and Amphenol.
What’s next for Bel Fuse
The company reports second-quarter earnings on July 29. Public search interest for Bel Fuse is near a yearly low, a contrast with the analyst enthusiasm. That gap — quiet retail interest alongside a wall of Buy ratings — will be tested when the numbers come out.
