NTRS vs STT: 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). NTRS is the smaller challenger ($33.33B), actually pricier on forward earnings (14.42x): 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.
NTRS vs STT: 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 | NTRS | STT | What it tells you |
|---|---|---|---|
| Market cap | $33.33B | $50.59B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 14.42 | 12.08 | 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 | 15.65 | 16.25 | 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 | 1.26 | 1.43 | 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 | 87% of range | 90% 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 | 2.79 | 2.12 | 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 NTRS and STT 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. NTRS and STT 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 NTRS and STT 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 Northern Trust Corporation (NTRS) do?
Northern Trust Corporation is a Chicago-based financial holding company built around two client segments: Asset Servicing (custody, fund administration, securities lending, foreign exchange and related institutional services) and Wealth Management (private banking, trust, and investment services for wealthy families, family offices, and institutions). It sits alongside BNY and State Street as one of the handful of large custody banks in the world, with roughly $18.6 trillion in assets under custody and administration and about $1.8 trillion under management as of early 2026. Most of its revenue is fee-based, which makes it more capital-light and less credit-cyclical than a traditional lending bank, though net interest income on client deposits is still a meaningful contributor.
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.
NTRS vs STT: 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.
- NTRS drivers: Fee growth and operating leverage; Net interest income and deposits.
- STT drivers: Record custody and AUM scale; Net interest income tailwind.
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: As a custody bank, Northern Trust is exposed to market levels because fees scale with asset values, so an equity or bond selloff pressures revenue. For 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.
NTRS or STT: 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 NTRS if you believe its drivers more; STT 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 NTRS and STT guides.
NTRS vs STT: the full fundamentals
NTRS. Q1 2026 revenue was about $2.21 billion (up 14 percent year over year) and net income about $525 million (up 34 percent), with diluted EPS of $2.71 well ahead of expectations. Market cap was roughly $32 billion in mid-2026, putting the stock at a mid-teens earnings multiple typical of a fee-driven custody bank. Figures are approximate and drawn from company reports and market data; verify current numbers before acting.
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.
Headline figures (approximate, JULY 2026): NTRS shows revenue (ttm) ~$8.7B, net income (ttm) ~$1.9B, eps (q1 2026) ~$2.71, market cap ~$32B; 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.
The bottom line: NTRS vs STT
NTRS and STT 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 NTRS and STT exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between NTRS and STT?
+
Northern Trust Corporation is a Chicago-based financial holding company built around two client segments: Asset Servicing (custody, fund administration, securities lending, foreign exchange and related institutional services) and Wealth Management (private banking, trust, and investment services for wealthy families, family offices, and institutions). State Street Corporation is a global financial services firm built on two engines. 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 NTRS or STT the better stock?
+
Neither is universally better. STT is the larger incumbent; NTRS 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, NTRS or STT?
+
On forward P/E (as of August 2026), NTRS trades at 14.42x and STT at 12.08x, 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 NTRS and STT?
+
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 NTRS vs STT?
+
NTRS: As a custody bank, Northern Trust is exposed to market levels because fees scale with asset values, so an equity or bond selloff pressures revenue. Net interest income is sensitive to interest-rate moves and deposit outflows. The business is heavily regulated and operationally complex, leaving it exposed to compliance, cyber, and processing risk across trillions in serviced assets. Fee compression from competition with BNY, State Street, and lower-cost providers is a persistent margin threat. Finally, the recurring merger speculation creates event risk: shares can react sharply to reports that may never lead to a deal, and management has denied any sale intent. 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.
