BAC vs BLK: How Bank of America and BlackRock Compare (2026)

Last updated July 2026

Short answer

BAC is the larger of the two ($435.53B market cap): the incumbent the market prices for continued execution (11.76x forward earnings, beta 1.17). BLK is the smaller challenger ($178.95B), actually pricier on forward earnings (17.10x): 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.

BAC vs BLK: the tie-breaker metrics

Same yardstick, side by side (as of July 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.

MetricBACBLKWhat it tells you
Market cap$435.53B$178.95BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E11.7617.10Valuation 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/E14.3326.39Valuation 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.
Beta1.171.44Volatility 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 range95% of range61% of rangeWhere 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 / book1.583.02How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Reading it: BAC 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 BAC and BLK 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. BAC and BLK 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 BAC and BLK 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.

BAC vs BLK: 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.

  • BAC drivers: Net interest income from deposit franchise; Investment banking and trading recovery.
  • BLK drivers: Record scale and inflows; Private markets build-out.

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: Credit quality is the eternal bank risk; consumer and commercial credit losses cyclically. For 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.

BAC or BLK: 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 BAC if you believe its drivers more; BLK 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 BAC and BLK guides.

BAC vs BLK: the full fundamentals

BAC. BAC trades at a modest P/E typical of large US banks. The valuation balances the durable consumer deposit franchise and capital markets recovery against credit cycle uncertainty and regulatory capital requirements. Price-to-book around 1.1x is consistent with ROE around 10%.

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.

Headline figures (approximate, early 2026): BAC shows revenue (ttm) ~$100 billion, net income (ttm) ~$28 billion, eps (ttm) ~$3.50, p/e (ttm) ~13x; 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.

The bottom line: BAC vs BLK

BAC and BLK 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 BAC and BLK exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between BAC and BLK?

+

Bank of America is the second-largest US bank by assets, behind JPMorgan Chase. BlackRock is a New York-based investment manager that oversees money for institutions, governments, and individuals worldwide. 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 BAC or BLK the better stock?

+

Neither is universally better. BAC is the larger incumbent; BLK 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, BAC or BLK?

+

On forward P/E (as of July 2026), BAC trades at 11.76x and BLK at 17.10x, so BAC 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 BAC and BLK?

+

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 BAC vs BLK?

+

BAC: Credit quality is the eternal bank risk; consumer and commercial credit losses cyclically. Interest rate cycles affect net interest income materially. Regulatory capital requirements can constrain capital return. 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.
