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

Last updated September 2026

Short answer

TEL is the larger of the two ($60.22B market cap): the incumbent the market prices for continued execution (16.12x forward earnings, beta 1.16). ST is the smaller challenger ($5.96B), cheaper on forward earnings (10.01x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

ST vs TEL: the tie-breaker metrics

Same yardstick, side by side (as of September 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.

MetricSTTELWhat it tells you
Market cap$5.96B$60.22BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E10.0116.12Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up.
Trailing P/E66.1020.37Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price.
Beta1.261.16Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through.
Price vs 52-week range50% of range28% of rangeWhere today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why.
Price / book2.024.55How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Reading it: ST 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.

Before you buy: how ST and TEL affect your concentration

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. ST 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 ST 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.

What does Sensata Technologies Holding plc (ST) do?

Sensata Technologies Holding plc is a global industrial technology company that designs and makes sensors, high-voltage protection, and electrical components used mainly in automotive, heavy-vehicle and off-road, industrial, and aerospace applications. It reports in two segments: Performance Sensing, which supplies sensors and high-voltage solutions for cars and heavy vehicles (things like tire-pressure monitoring, thermal management, electrical protection, and powertrain sensing) and made up roughly 70% of sales in fiscal 2024, and Sensing Solutions, which sells application-specific pressure, temperature, and position sensors plus motor protectors, high-voltage contactors, relays, and battery-management products into industrial and other markets. Because most of its revenue is tied to vehicle production, Sensata's results track global light-vehicle build rates and its ability to win content on new platforms far more than any one product line.

ST vs TEL: how do they differ?

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

  • ST drivers: Margin recovery and cost execution; Electrification content per vehicle.
  • TEL drivers: AI data center connectivity; Vehicle electrification and content growth.

Which fits which kind of investor

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: The dominant risk is automotive cyclicality: with most revenue tied to vehicle production, a slowdown in global light-vehicle builds can pressure volumes, and prolonged softness tends to show up later as program churn and factory under-absorption. 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.

ST or TEL: which should you pick?

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 ST 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 ST and TEL guides.

ST vs TEL: the full fundamentals

ST. Figures are approximate and tied to the asOf date; verify live numbers before acting. The trailing P/E near triple digits is misleading because it divides the price by earnings that were depressed by large 2024 and 2025 goodwill and restructuring charges, so the forward P/E around 12x is the more useful gauge. For a cyclical auto supplier, the valuation ultimately hinges on where vehicle production and margins sit in the cycle rather than on a single multiple.

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, July 2026): ST shows revenue (ttm) ~$3.7 billion (Q1 2026 was ~$934.8 million, up ~2.6% year over year), adjusted eps (q1 2026) ~$0.86 (GAAP EPS ~$0.59), net income (q1 2026) ~$87 million attributable to common shareholders, market cap ~$7 billion (mid-cap); TEL shows revenue (ttm) ~$17B, quarterly sales (recent) ~$4.5B, adjusted operating margin ~20%, market cap ~$59B.

The bottom line: ST vs TEL

ST 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. Walnut can show your combined ST and TEL exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between ST and TEL?

+

Sensata Technologies Holding plc is a global industrial technology company that designs and makes sensors, high-voltage protection, and electrical components used mainly in automotive, heavy-vehicle and off-road, industrial, and aerospace applications. TE Connectivity (NYSE: TEL) designs and manufactures connectors, sensors, and interconnect systems that move power and data through cars, factories, data centers, aircraft, appliances, and medical devices. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is ST or TEL the better stock?

+

Neither is universally better. TEL is the larger incumbent; ST is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, ST or TEL?

+

On forward P/E (as of September 2026), ST trades at 10.01x and TEL at 16.12x, so ST is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both ST and TEL?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of ST vs TEL?

+

ST: The dominant risk is automotive cyclicality: with most revenue tied to vehicle production, a slowdown in global light-vehicle builds can pressure volumes, and prolonged softness tends to show up later as program churn and factory under-absorption. Leverage is a structural risk because net debt of roughly $2.3 billion leaves less cushion if demand weakens or refinancing costs rise. Electrification is both an opportunity and a hazard, since Sensata has already taken large charges (including a $259 million goodwill impairment and EV-program-related restructuring) when EV adoption ran slower than planned. Customer concentration and pricing pressure from large automakers can squeeze margins. The very high trailing P/E reflects depressed prior-period earnings from those charges, so the trailing multiple overstates valuation and the forward multiple is the more meaningful read. TEL: TEL's largest markets, automotive and industrial, are cyclical, so a downturn in vehicle production or capital spending can pressure revenue and margins. A meaningful share of the current excitement rests on AI data center demand, which could prove lumpy or slow if hyperscaler capital spending cools. Competition is intense from Amphenol, which has been closing the revenue gap, plus Molex, Aptiv, and others, which can squeeze pricing. As a global manufacturer, TEL is exposed to tariffs, supply chain costs, and foreign currency swings. Finally, the stock trades at a full multiple for an industrial, so disappointing growth could compress valuation.
