Is Nu Holdings Stock a Buy, Sell, or Hold With Shares 20% Below Their 52-Week High?

Nu added 4 million customers in Q2 2026, lifting its customer base to 139 million, while revenue rose 39% year over year and net income increased 49% to more than $1 billion. ARPU climbed to $17.10 from $11.60, supported by cross-selling and deeper monetization of longer-tenured customers. New bank charters in Mexico and Brazil, plus a U.S. charter application, support geographic expansion, although investors remain focused on credit risk as Nu expands lending. The article argues Nu's 20x trailing earnings valuation is attractive despite its 5.5x price-to-book multiple and shares trading about 20% below their high.

Analysis

NU’s next leg is less about customer additions than whether it can convert newly licensed deposit-gathering capacity into cheaper funding without loosening underwriting. If deposit mix replaces higher-cost wholesale funding, net interest margin and credit-card unit economics can improve simultaneously; if credit growth outruns collections, the same balance-sheet expansion makes the equity materially more rate- and loss-sensitive than its fintech narrative implies. The key near-term read-through is not reported ARPU alone, but cohort-level ARPAC, cost of risk, 90+ day delinquency, and deposit beta by Brazil and Mexico.

The competitive pressure is most acute for Brazilian incumbents ITUB, BBD and BBDC and Mexican banks with expensive branch networks, but their response should be pricing rather than customer acquisition. That could cap NU’s lending yields and interchange economics just as it pushes into affluent and SMB segments, where acquisition costs, service expectations, and credit complexity are higher. A U.S. launch is strategically valuable only if it is narrowly targeted; broad expansion would likely dilute returns because NU lacks a demonstrated U.S. funding, underwriting, and distribution advantage against SOFI, Chime and incumbent banks.

Consensus appears to treat the multiple as justified by growth, while underweighting the nonlinear downside from a Brazilian or Mexican consumer-credit turn. At a premium-to-book valuation, even a modest upward revision in normalized losses can cause both earnings cuts and multiple compression. Conversely, sustained operating leverage alongside stable delinquency vintages would validate a transition from a credit-card-led fintech to a lower-cost regional deposit franchise over 6-18 months.

Key Decisions for Investors

• Maintain a tactical long NU only into the next earnings print if quarterly cost of risk is flat-to-down and deposit growth exceeds loan growth; target a 10-15% upside over 1-3 months, but exit on a >50 bp sequential deterioration in risk-adjusted NIM or a material rise in 90+ day delinquencies.
• Express the competitive-disruption thesis as long NU / short BBDC or BBD over 6-12 months, sized modestly for Brazil macro beta. The pair works if NU funds growth through deposits and incumbents defend share through lower pricing; cover if NU’s credit-loss ratio worsens while incumbents preserve NIM.
• Do not underwrite U.S. optionality into valuation yet. Set an alert for a disclosed U.S. product scope, capital commitment, and customer-acquisition cost; a broad unsecured-credit rollout would be a thesis risk rather than a catalyst.
• For downside protection around earnings, consider a 3-month NU put spread financed only after a post-results rally: buy the ~10% OTM put and sell the ~20% OTM put. This targets the asymmetric risk of a credit-quality reset without abandoning upside from continued monetization.
