StoneCo: Cheap, Out of Favor, and Worth a Tactical Buy into a Rate-Relief Play

Hook and thesis

StoneCo Ltd. is trading at $9.60 today and looks like a classic “cheap for a reason” story that now merits a tactical, mid-term long. The company’s market cap is roughly $2.32 billion and the stock changes hands at a strikingly low P/E of 3.7 and a P/B of 1.24. Those multiples scream value, but the market has punished STNE for Brazil-specific macro risks - chiefly high interest rates and inflation - which have weighed on credit growth and sentiment.

My thesis: if Brazilian monetary conditions stop getting worse or show the first signs of easing, the market will re-rate StoneCo quickly because its core merchant payments business and a growing credit stack can translate steady revenue into outsized EPS when funding costs normalize. That creates an asymmetric trade: limited downside from current levels (recent 52-week low $9.08) and meaningful upside if the macro shock subsides.

What StoneCo does and why the market should care

StoneCo is a São Paulo-based fintech that provides payments, point-of-sale software and credit products to merchants across in-store, online and mobile channels. The business benefits from scale: payments and software revenue are relatively high-margin and recurring; the credit arm can enhance lifetime value of merchant clients when managed responsibly.

Investors care because the company sits at the intersection of commerce digitization and financial services in Brazil - a market that can grow faster than developed peers. When macro conditions are calm, merchant volumes and credit expansion drive strong top-line growth and margin expansion. When rates spike, the credit book growth stalls and multiples compress rapidly, which is what we have seen recently.

Supporting numbers

Why now

Three practical reasons to consider a tactical long now:

• Valuation is compelling. A P/E of 3.7 implies either the market expects EPS to collapse or there is an outright mispricing. With earnings power that has shown improvement historically (earnings metrics cited in coverage earlier this year), the multiple already embeds very pessimistic outcomes.
• Short interest and short-volume are elevated. As of 07/31/2026 short interest stood at ~16.2M shares with days to cover around 5.06; recent short volume on 08/24/2026 was roughly 854,785 of 1,666,008 total volume (about half). Heavy positioning can amplify rallies if sentiment shifts.
• Technicals are constructive for a mean-revert trade. RSI near 38 makes the name not severely oversold but more favorable for a bounce; the stock is trading just below its 10-day SMA ($9.57) and under its 20/50-day moving averages ($10.32 / $10.71), giving scope for a re-test of those levels if momentum returns.

Valuation framing

At $9.60 the company’s market cap is $2.32 billion. The P/E of 3.7 is low relative to typical fintech peers and even many cyclical businesses; P/B of 1.24 suggests tangible book support. The 52-week peak of $19.95 implies there is precedent for much higher market expectations, but that peak occurred in a markedly different macro regime.

Qualitatively, if StoneCo can stabilize merchant volumes and re-accelerate credit growth without a meaningful increase in loan losses, a multiple re-rating toward more normalized fintech multiples would drive clear upside. Even a re-rating to a modest P/E in the low double digits would imply material upside from current levels.

Catalysts (near- and mid-term)

• Signs of Brazilian monetary easing or even a pause in rate hikes that reduces funding cost pressure and brings clarity to credit economics.
• Quarterly results showing continued merchant volume growth and stabilization or margin improvement in the credit business.
• Investor-friendly capital actions (repeat dividends, share buybacks or clearer capital return policy) - the $2.53 distribution earlier this year signals management is willing to return capital.
• Short-covering via elevated short interest if sentiment swings positive on the macro or execution front.

Trade plan (actionable)

Direction: Long

Entry price: $9.60

Target price: $13.50

Stop loss: $8.80

Horizon: mid term (45 trading days). I view this as a swing trade: time is set so the position benefits from any near-term macro relief or company-specific beats, while limiting exposure to longer-duration macro shifts that could re-compress multiples.

Rationale for sizing and horizon: keep position size limited until Brazil rate trajectory becomes clearer. The stop at $8.80 is below the most recent intra-period lows but tight enough to protect capital if negative macro news accelerates. The target of $13.50 gives a clear reward/risk (roughly 40% upside vs ~8% downside to stop) and is achievable with a modest multiple re-rating or recovery in merchant volumes.

Risks and counterarguments

• Macro risk - elevated interest rates. Brazil’s high rates are the primary headwind. If rates remain high or the central bank tightens further, credit growth and margins could deteriorate and multiples can compress further.
• Currency and capital-flow risk. A weaker real versus the dollar or a capital flight episode can hurt investor sentiment and complicate dollar-based valuations even if operational metrics are stable.
• Credit execution risk. Expansion of the credit book can boost returns in benign cycles; but missteps or higher-than-expected delinquencies would meaningfully hit EPS when funding is expensive.
• Regulatory and competitive risk. Brazil’s fintech space is competitive and regulatory shifts (consumer protection, lending rules, interchange changes) could damage unit economics.
• Dividend not a guarantee. The $2.53 per share distribution earlier in 2026 shows management can return capital, but it may not be repeatable if macro weakens or liquidity needs increase.

Counterargument

One can reasonably argue StoneCo is cheap for structural reasons: persistent high rates may permanently shrink the addressable opportunity for credit-financed merchant growth, pushing fair multiples lower. If investor fears about Brazil’s macro outlook are justified and long-lived, earnings could fall materially and the market might not re-rate the stock despite apparent bargain multiples. That scenario argues for a small, tactical position size rather than a full-scale buy.

Conclusion and what would change my mind

I recommend a tactical long in STNE at $9.60 for a mid-term trade (45 trading days) with a target of $13.50 and stop at $8.80. The set-up is asymmetric: the company is cheap on trailing multiples, has cash-generating merchant flows, and carries elevated short positioning that could accelerate any recovery. The trade depends on a stabilization or improvement in Brazil’s rate outlook and company execution.

I would change my view if any of the following occur: (1) Brazil’s central bank signals further aggressive tightening or rate-path extension, (2) quarterly results show sharp deterioration in loan performance or materially weaker merchant volumes, or (3) management withdraws capital returns or signals a need to conserve liquidity. Conversely, a clear sign of rate easing, a better-than-feared quarter, or a repeatable capital-return program would make me move from a tactical trade to a larger position.
