SBGSY vs SIEGY: Which Is the Better Buy in 2026?

Last updated October 2026

Short answer

SIEGY is the larger of the two ($229.75B market cap): the incumbent the market prices for continued execution (20.61x forward earnings, beta 1.29). SBGSY is the smaller challenger ($157.44B), priced similarly on forward earnings (19.93x): 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.

SBGSY vs SIEGY: the tie-breaker metrics

Same yardstick, side by side (as of October 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.

Metric	SBGSY	SIEGY	What it tells you
Market cap	$157.44B	$229.75B	Size. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E	19.93	20.61	Valuation 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/E	28.81	25.74	Valuation 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.
Beta	1.13	1.29	Volatility 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 range	25% of range	64% of range	Where 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 / book	5.73	3.03	How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Before you buy: how SBGSY and SIEGY 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. SBGSY and SIEGY 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 SBGSY and SIEGY 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 Schneider Electric SE (SBGSY) do?

Schneider Electric SE sells the equipment and software that move and control electricity inside buildings, data centers, factories and utility grids. It reports two businesses. Energy Management (switchgear, circuit breakers, low and medium voltage distribution, uninterruptible power supplies, prefabricated data center modules, cooling and building controls) produced €17.6 billion of the Group's €21.2 billion of revenue in the first half of 2026, at a 22.4% adjusted EBITA margin. Industrial Automation (PLCs, drives, motion control, process systems and the AVEVA industrial software business) produced €3.6 billion at a 14.0% margin. By business model, products were 47% of 2025 revenue, systems 34% and software and services 19%. North America is the largest region at about 40% of second-quarter 2026 revenue, followed by Europe (24%), China and East Asia (18%) and South Asia and International (18%).

What does Siemens AG (SIEGY) do?

Siemens AG is one of Europe's largest industrial technology companies, headquartered in Munich. It runs four main businesses: Digital Industries (factory automation hardware such as PLCs and drives, plus industrial software including Xcelerator, Teamcenter, NX and the recently acquired Altair and Dotmatics), Smart Infrastructure (electrical products, grid technology and building systems, a big beneficiary of data center and electrification spending), Mobility (rail vehicles, signaling and rail software), and a roughly 67% stake in Siemens Healthineers, the medical imaging and diagnostics company that Siemens plans to separate. Fiscal years end on September 30, and US investors typically hold the company through the SIEGY sponsored ADR, which trades over the counter in dollars rather than on a US exchange. The company employs roughly 300,000 people, sells in close to 190 countries and generates a large share of revenue outside Germany, with the US and China among its biggest markets.

SBGSY vs SIEGY: 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.

SBGSY drivers: Data center power and cooling; Grid and electrification spending.
SIEGY drivers: Electrification and data center demand at Smart Infrastructure; Industrial software and the Altair and Dotmatics deals.

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 biggest risk is concentration in one buyer group: data center demand has driven most of the recent acceleration, and Schneider's results would feel any pause in hyperscaler or AI infrastructure capital spending quickly, because fast-growing systems revenue is project-based. For SIEGY, siemens is cyclical at the margin: an industrial slowdown, weaker China demand or a pause in data center spending would hit orders and the premium multiple at the same time.

SBGSY or SIEGY: 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 SBGSY if you believe its drivers more; SIEGY 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 SBGSY and SIEGY guides.

SBGSY vs SIEGY: the full fundamentals

SBGSY. Revenue and profit are in euros, because Schneider reports under IFRS in Paris; the ADR price converts them through the exchange rate. At $56.96 the ADR trades at about 29 times trailing and 20 times forward earnings, cheaper than in the summer after a 13% drop in the month to October 16 that followed the PTC announcement. Third-quarter revenue of €11.46 billion beat the €11.13 billion consensus and organic growth of 16.9% beat the 13.8% expected, and the company raised its 2026 target again, so the debate has moved from demand to the price and financing of PTC. Full-year 2026 results are due in late February 2027.

SIEGY. At a Frankfurt share price around €240, Siemens trades at roughly 21 times the midpoint of its raised fiscal 2026 EPS guidance, a premium to its own history and to many diversified industrials but below pure-play electrification and automation names such as Schneider Electric. The SIEGY ADR represents one-half of an ordinary share, so its dollar price is roughly half the euro share price converted at the current exchange rate. Full fiscal 2026 results are due in mid-November 2026. The quarterly cadence matters for ADR holders: results arrive in November, February, May and August, and the ADR typically reacts in the US session following the morning German release.

Headline figures (approximate, October 2026): SBGSY shows revenue (ttm to june 2026) ~€42.0 billion, revenue (9 months to sept 2026) ~€32.7 billion (+15.0% organic), q3 2026 revenue ~€11.46 billion (+16.9% organic), operating margin (ttm) ~18.2%; SIEGY shows revenue (ttm) ~€81 billion, fiscal q3 2026 orders ~€27.9 billion (book-to-bill ~1.34), order backlog ~€132 billion, fy2026 eps pre-ppa guidance ~€11.20 to €11.50.

FAQ

What is the difference between SBGSY and SIEGY?

Schneider Electric SE sells the equipment and software that move and control electricity inside buildings, data centers, factories and utility grids. Siemens AG is one of Europe's largest industrial technology companies, headquartered in Munich. 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 SBGSY or SIEGY the better stock?

Neither is universally better. SIEGY is the larger incumbent; SBGSY 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, SBGSY or SIEGY?

On forward P/E (as of October 2026), SBGSY trades at 19.93x and SIEGY at 20.61x, so SBGSY 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 SBGSY and SIEGY?

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 SBGSY vs SIEGY?

SBGSY: The biggest risk is concentration in one buyer group: data center demand has driven most of the recent acceleration, and Schneider's results would feel any pause in hyperscaler or AI infrastructure capital spending quickly, because fast-growing systems revenue is project-based. Input costs are a second pressure point; in the first half of 2026 raw material inflation, mainly copper and silver, took €330 million from adjusted EBITA and tariffs a net €104 million, and management has to keep raising prices to stay net price positive. Mix works against margins too, since faster systems growth diluted gross margin by 0.7 points in the half. Geopolitics matters: the Middle East was under 5% of 2025 revenue but management flagged conflict-related disruption for the second half of 2026, with possible strain on supply chains and inflation, while China residential and US residential demand remain weak. Acquisitions now carry the largest execution risk in years: the $22.6 billion PTC deal needs approvals and is not expected to close until the third quarter of 2027, it will be funded with up to €17 billion of new debt and a €5 billion to €6 billion equity raise that dilutes existing holders, and revenue synergies may come later and smaller than planned. Cognite ($3.1 billion), Shelly (about €1.2 billion) and AiDASH add to the integration load, and net debt was already €15.4 billion in June. For SBGSY holders specifically, the ADR is unsponsored and trades over the counter, so volumes and spreads can be less favorable than in Paris; the dollar price moves with EUR/USD (the company now expects a €300 million to €400 million currency hit to 2026 revenue), and dividends are paid once a year net of French withholding tax and depositary fees. Valuation could compress if growth slows toward the 7% to 10% medium-term target; the ADR fell 13.3% in the month to October 16, 2026, mostly on the PTC announcement and a wider sell-off in AI-linked stocks. SIEGY: Siemens is cyclical at the margin: an industrial slowdown, weaker China demand or a pause in data center spending would hit orders and the premium multiple at the same time. Software acquisitions carry integration and goodwill risk, and Mobility has a history of lumpy, lower-margin contracts. Tariffs and trade friction between the US, EU and China affect a company with factories and customers in all three. For SIEGY holders specifically, the ADR is priced in dollars but the business reports in euros, so a stronger dollar can reduce returns even if the underlying shares rise, and German withholding tax on dividends (with depositary fees) reduces the net payout. As an OTC ADR, SIEGY can also have wider spreads and thinner trading than the Frankfurt listing, and corporate actions such as the Healthineers distribution may be handled differently for ADR holders (for example sold for cash) than for ordinary shareholders. Finally, the stock has re-rated on record orders, so a quarter of slower bookings could weigh on the shares more than on the fundamentals.
