BELFB vs TEL: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: TEL is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BELFB and TEL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BELFB and TEL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Bel Fuse designs and manufactures a broad range of electronic components used inside other companies' equipment. Its products span three product groups: Power Solutions and Protection (front-end, board-mount and industrial power supplies plus circuit-protection fuses), Connectivity Solutions (fiber-optic, copper, RF and RJ connectors and cable assemblies), and Magnetic Solutions (integrated connector modules, transformers and inductors). These parts go into networking, telecom, computing, industrial, defense, commercial aerospace, transportation and eMobility systems, which makes Bel a supplier to the broader electronics and infrastructure build-out rather than a consumer-facing brand.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• BELFB drivers: Mix shift to aerospace and defense; Data-center and AI-infrastructure demand.
• TEL drivers: AI data center connectivity; Vehicle electrification and content growth.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Bel Fuse's demand is cyclical and project-driven, so orders can fall quickly when networking, industrial or computing customers cut spending or work down inventory. For TEL, tEL's largest markets, automotive and industrial, are cyclical, so a downturn in vehicle production or capital spending can pressure revenue and margins.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BELFB if you believe its drivers more; TEL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BELFB and TEL guides.

BELFB. Bel reported record full-year 2025 sales of about $675.5 million, up roughly 26%, with GAAP net earnings of about $61.5 million and EPS near $4.87, and gross margin expanding to about 39%. Fourth-quarter GAAP results included a $13.1 million non-cash impairment tied to its Innolectric equity investment, while non-GAAP quarterly earnings still rose year over year. After a large share-price run (a 52-week range from roughly $92 to over $314), the trailing P/E has re-rated well above its historical norm, and the dividend is small relative to the share price.

TEL. TEL trades around $200 per share for a market cap near $59 billion, at roughly 20 times earnings, a valuation typical of a quality industrial compounder rather than a cheap cyclical. It generates strong free cash flow (around $1 billion in a recent quarter) and yields about 1.5 percent. The premium reflects record AI-driven orders and steady margin expansion.

Headline figures (approximate, FEBRUARY 2026): BELFB shows revenue (fy2025) ~$675.5 million, net earnings (fy2025, gaap) ~$61.5 million, eps (fy2025) ~$4.87, adjusted ebitda (fy2025) ~$142.9 million; TEL shows revenue (ttm) ~$17B, quarterly sales (recent) ~$4.5B, adjusted operating margin ~20%, market cap ~$59B.

BELFB and TEL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
