STT vs WT: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
STT is the larger of the two ($50.59B market cap): the incumbent the market prices for continued execution (12.08x forward earnings, beta 1.43). WT is the smaller challenger ($2.96B), actually pricier on forward earnings (15.10x): 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.
STT vs WT: the tie-breaker metrics
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.
| Metric | STT | WT | What it tells you |
|---|---|---|---|
| Market cap | $50.59B | $2.96B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 12.08 | 15.10 | 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 | 16.25 | 35.22 | 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 | 1.43 | 1.18 | 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 | 90% of range | 82% 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 | 2.12 | 6.09 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: STT 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 STT and WT 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. STT and WT 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 STT and WT 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 State Street Corporation (STT) do?
State Street Corporation is a global financial services firm built on two engines. The first is investment servicing: it acts as custodian and administrator for institutional investors, holding a record roughly $54.5 trillion in assets under custody and/or administration (AUC/A) as of April 2026 and earning fees for safekeeping, fund accounting, and related back-office services. The second is State Street Global Advisors, its asset-management arm, which ran about $5.6 trillion in assets under management and is best known for the SPDR ETF lineup, including SPY, the original US-listed exchange-traded fund. The company also generates net interest income from the deposits institutional clients park with it.
What does WisdomTree (WT) do?
WisdomTree is a New York-based global asset manager that designs and runs exchange-traded products, primarily ETFs, across equities, fixed income, commodities, currencies, and model portfolios. Like other ETF sponsors, it earns advisory fees calculated as a percentage of assets under management, so its revenue scales with the size of its funds. Growth comes from two sources: net inflows into its products (organic growth) and the appreciation of the assets already in those funds (market growth). WisdomTree differentiates through self-indexed and factor-based strategies rather than competing head-on as a pure low-cost passive provider, which lets it charge somewhat higher fees than the largest index giants.
STT vs WT: 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.
- STT drivers: Record custody and AUM scale; Net interest income tailwind.
- WT drivers: Record AUM and strong organic flows; Operating leverage and margin expansion.
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: State Street's fee revenue is tightly linked to market values, so an equity drawdown or outflows from passive funds would pressure earnings directly. For WT, the central risk is that WisdomTree's fee revenue is tied to AUM, so a market downturn or a reversal in fund flows would cut earnings directly, and outflows can compound the effect of falling markets.
STT or WT: 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 STT if you believe its drivers more; WT 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 STT and WT guides.
STT vs WT: the full fundamentals
STT. As of April 2026 State Street traded around a high-teens price-to-earnings multiple, typical for a scale custody bank valued on stable fee income plus interest earnings rather than rapid growth. The stock reached an all-time high near $175 after Q1 results beat expectations. Its valuation tends to move with expectations for equity markets, passive flows, and interest rates.
WT. These are qualitative characterizations tied to the asOf date, not precise live figures; confirm current numbers before acting. WisdomTree's fundamentals have clearly improved (record AUM, fast revenue growth, expanding margins), but its earnings ride markets and flows, so a downturn could reverse the trend quickly. The gap between adjusted and GAAP results means headline EPS can look weak even in a strong operating quarter, so it helps to look at AUM, flows, and adjusted margins alongside reported earnings. The tokenization story is real optionality but should be weighed as an emerging bet, not a proven earnings driver.
Headline figures (approximate, APRIL 2026): STT shows revenue (ttm) ~$14B, q1 2026 revenue ~$3.8B (up ~16% YoY), q1 2026 diluted eps ~$2.49 (adjusted ~$2.84), market cap ~$50B; WT shows assets under management Record ~$153 billion in Q1 2026, a fifth straight record quarter, up sharply year over year, revenue trend Growing fast; Q1 2026 operating revenue ~$160 million, up ~48% year over year, flows Strong; several billion dollars of net inflows and a double-digit annualized organic growth rate, margins Expanding; adjusted operating margin rose several hundred basis points year over year.
The bottom line: STT vs WT
STT and WT 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 STT and WT exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between STT and WT?
+
State Street Corporation is a global financial services firm built on two engines. WisdomTree is a New York-based global asset manager that designs and runs exchange-traded products, primarily ETFs, across equities, fixed income, commodities, currencies, and model portfolios. 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 STT or WT the better stock?
+
Neither is universally better. STT is the larger incumbent; WT is the smaller challenger and looks pricier 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, STT or WT?
+
On forward P/E (as of August 2026), STT trades at 12.08x and WT at 15.10x, so STT 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 STT and WT?
+
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 STT vs WT?
+
STT: State Street's fee revenue is tightly linked to market values, so an equity drawdown or outflows from passive funds would pressure earnings directly. Net interest income depends on rates and deposit behavior, both of which can reverse quickly. Indexing is a low-margin, price-competitive business where fee compression is a persistent headwind against BlackRock and Vanguard. The custody business is concentrated in a small number of very large clients, so losing or repricing a major mandate matters. As a systemically important bank, it also faces heavy regulatory capital requirements and operational-risk exposure across trillions in serviced assets. WT: The central risk is that WisdomTree's fee revenue is tied to AUM, so a market downturn or a reversal in fund flows would cut earnings directly, and outflows can compound the effect of falling markets. Fee compression across the ETF industry is a structural headwind, as investors keep pushing toward the lowest-cost products offered by far larger rivals like BlackRock, Vanguard, and State Street. The digital-assets and tokenization business, while promising, is still small, unprofitable historically, and exposed to shifting crypto regulation and adoption uncertainty, so it may not pay off on the timeline bulls expect. WisdomTree is also a mid-sized manager competing against giants with vastly greater scale and distribution, and it has carried meaningful debt and reported GAAP losses in periods affected by non-operating items, so headline earnings can be noisy even when the underlying fee business is growing.
