BLK vs WT: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
BLK (BlackRock) and WT (WisdomTree) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
BLK 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 | BLK | WT | What it tells you |
|---|---|---|---|
| Forward P/E | 16.94 | 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 | 26.11 | 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 | 1.44 | 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 | 57% 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 | 2.99 | 6.09 | 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 BLK 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. BLK 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 BLK 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. Walnut is not an investment adviser.
What does BlackRock (BLK) do?
BlackRock is a New York-based investment manager that oversees money for institutions, governments, and individuals worldwide. Its franchises span index funds and iShares ETFs, active equity and fixed income, cash management, and a rapidly expanding private-markets arm built through the 2024-2025 acquisitions of Global Infrastructure Partners, HPS Investment Partners, and the private-markets data provider Preqin. The Aladdin platform, which powers risk and portfolio management for BlackRock and outside clients, anchors a technology-services business that reached roughly $2 billion in annual revenue.
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.
BLK 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.
- BLK drivers: Record scale and inflows; Private markets build-out.
- 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: BlackRock's fee revenue is tied to market levels, so a sustained equity or bond drawdown would pressure assets under management and base fees. 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.
BLK or WT: which should you pick?
BLK vs WT: the full fundamentals
BLK. BlackRock trades at a premium to smaller asset managers, reflecting its scale, technology revenue, and private-markets expansion. Base fees move with assets under management, so quarterly results track market levels and net flows. The next earnings report is scheduled for July 21, 2026.
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, JULY 2026): BLK shows assets under management ~$13.9 trillion, revenue (ttm) ~$25.6 billion, q1 2026 revenue ~$6.7 billion (up ~27% YoY), market cap ~$160 billion; 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: BLK vs WT
BLK 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 BLK and WT exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between BLK and WT?
+
BlackRock is a New York-based investment manager that oversees money for institutions, governments, and individuals worldwide. 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 BLK or WT the better stock?
+
Neither is universally better; they suit different views and risk levels. 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, BLK or WT?
+
On forward P/E (as of August 2026), BLK trades at 16.94x and WT at 15.10x, so WT 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 BLK 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 BLK vs WT?
+
BLK: BlackRock's fee revenue is tied to market levels, so a sustained equity or bond drawdown would pressure assets under management and base fees. Long-running fee compression in index and ETF products squeezes margins on its largest franchises. The push into private markets adds integration risk and a heavier debt load from multibillion-dollar deals. The firm also faces political and regulatory scrutiny over its size, index-fund voting power, and past ESG positioning, which can create headline and legal risk. Competition from Vanguard, State Street, and lower-cost entrants remains intense. 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.
