SIEGY vs VWDRY: 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). VWDRY is the smaller challenger ($26.99B), cheaper on forward earnings (14.68x): 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.
SIEGY vs VWDRY: 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 | SIEGY | VWDRY | What it tells you |
|---|---|---|---|
| Market cap | $229.75B | $26.99B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 20.61 | 14.68 | 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 | 25.74 | 21.49 | 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 | 1.29 | 1.02 | 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 | 64% of range | 59% 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 | 3.03 | 6.14 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: VWDRY 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 SIEGY and VWDRY 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. SIEGY and VWDRY 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.

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.
What does Vestas Wind Systems (VWDRY) do?
Vestas Wind Systems, based in Aarhus, Denmark, designs, builds, installs and services wind turbines. It reports two segments. Power Solutions sells onshore and offshore turbines, and Service runs long-term maintenance contracts on a fleet of well over 180 GW installed worldwide. Vestas is the largest turbine maker outside China, with especially strong positions in Europe and the Americas. VWDRY is an American depositary receipt that trades over the counter in US dollars; three ADRs represent one ordinary share listed in Copenhagen under VWS. The company has roughly 37,000 employees.
SIEGY vs VWDRY: 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.
- SIEGY drivers: Electrification and data center demand at Smart Infrastructure; Industrial software and the Altair and Dotmatics deals.
- VWDRY drivers: Margin recovery in Power Solutions; A large, sticky service business.
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: 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. For VWDRY, uS policy is the most visible risk.
SIEGY or VWDRY: 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 SIEGY if you believe its drivers more; VWDRY 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 SIEGY and VWDRY guides.
SIEGY vs VWDRY: the full fundamentals
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.
VWDRY. Figures are as of late October 2026 and come from Vestas's 2025 annual report, its Q1 and Q2 2026 interim reports, and US market data for the ADR. Trailing revenue combines full-year 2025 with the first half of 2026. The ADR represents one third of a Copenhagen share, so the ~$9.24 price lines up with ~DKK 186 per ordinary share. At ~21x trailing earnings and ~6x book value, the market is pricing in further margin gains. Full-year 2026 guidance is EUR 20 to 22 billion of revenue at a 7% to 9% EBIT margin before special items. The dividend yield is small, at ~0.2%.
Headline figures (approximate, October 2026): 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; VWDRY shows revenue (ttm) ~EUR 20.3B (~$23.5B), ebit margin (q2 2026, before special items) ~9.4%, market cap ~$27.7B, p/e (trailing) ~21x.

FAQ
What is the difference between SIEGY and VWDRY?
+
Siemens AG is one of Europe's largest industrial technology companies, headquartered in Munich. Vestas Wind Systems, based in Aarhus, Denmark, designs, builds, installs and services wind turbines. 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 SIEGY or VWDRY the better stock?
+
Neither is universally better. SIEGY is the larger incumbent; VWDRY 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, SIEGY or VWDRY?
+
On forward P/E (as of October 2026), SIEGY trades at 20.61x and VWDRY at 14.68x, so VWDRY 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 SIEGY and VWDRY?
+
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 SIEGY vs VWDRY?
+
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. VWDRY: US policy is the most visible risk. The 2025 US budget law accelerated the phase-out of wind tax credits, and the current administration has halted or slowed several offshore projects, which can delay orders and push customers to rush or cancel projects. Tariffs on steel and imported components raise costs for turbines delivered into the US. Offshore wind remains a hard business: new factories, installation vessels and large 15 MW turbines carry execution risk, and a single quality problem can force large warranty provisions, as Vestas has experienced before. Chinese manufacturers such as Goldwind, Mingyang and Envision sell turbines far more cheaply and are pressing into Europe, Latin America and emerging markets. Wind projects are capital intensive, so higher interest rates and permitting delays can stall customer decisions. Results also swing quarter to quarter with delivery timing. For VWDRY holders specifically, returns are affected by the dollar against the Danish krone and euro, the ADR trades OTC with thinner volume (~270,000 ADRs a day) than the Copenhagen listing, and a depositary fee may be charged.
