BAC vs BB: How Bank of America and BlackBerry Compare (2026)

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.

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.

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 BB 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 BB 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.

Bank of America is the second-largest US bank by assets, behind JPMorgan Chase. The company is one of the four mega-bank holding companies (along with JPMorgan, Citigroup, and Wells Fargo) and operates across four main reporting segments. Consumer Banking is the largest retail bank in the US by deposits, serving over 60 million customers through ~3,800 branches. Global Wealth and Investment Management is one of the largest US wealth managers (anchored by Merrill Lynch). Global Banking provides commercial banking, treasury services, and investment banking to corporate and institutional clients. Global Markets provides trading services across fixed income, equities, and commodities.

BlackBerry is a software company built around two reporting segments. QNX makes a safety-certified real-time operating system and middleware used in cars (digital cockpits, advanced driver assistance, software-defined vehicle platforms) and in other embedded and IoT systems such as robotics, medical devices, and industrial controls. QNX earns money through development licenses and, more importantly, per-unit royalties paid as products ship, which builds a contracted royalty backlog that converts to revenue over time. The Secure Communications segment sells cybersecurity and secure messaging, unified endpoint management, and crisis-communication and emergency-notification software, with a customer base skewed toward governments, defense, and regulated enterprises. A third, smaller stream comes from BlackBerry's patent and licensing portfolio.

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.
• BB drivers: QNX royalty backlog and automotive software; Secure Communications and government demand.

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 BB, overall revenue growth is modest, often in the low-to-mid single digits, so the investment case leans heavily on QNX execution and backlog conversion.

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; BB 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 BB guides.

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%.

BB. BlackBerry trades at a price-to-sales multiple well above a typical hardware or legacy-tech name, reflecting expectations that QNX royalties and the embedded-software franchise can compound. That premium also means the market is pricing in continued execution; results that merely match low-single-digit total growth could leave the valuation looking stretched. Figures are tied to the June 2026 as-of date and will change with each quarterly report.

Headline figures (approximate, early 2026): BAC shows revenue (ttm) ~$100 billion, net income (ttm) ~$28 billion, eps (ttm) ~$3.50, p/e (ttm) ~13x; BB shows revenue (fy2026, ended feb 2026) ~$549M, up ~3% year over year, segment mix Secure Communications ~$259M; QNX grew ~14% full year (record Q4 ~$79M); plus Licensing/IP, qnx royalty backlog ~$950M of contracted future revenue, gaap net income (fy2026) ~$53M, up from a prior-year loss.

BAC and BB 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.
