ITUB · Itau Unibanco Holding S.A.

The thesis

Itaú Unibanco is a high-return Brazilian bank whose US shares now price in a market-friendly result in the 25 October 2026 presidential runoff. The vote and the 4 November 2026 third-quarter report decide whether the rally holds. The American depositary receipts (ADRs, the US-listed form of the shares) closed at $10.16 on 9 October 2026, a new 52-week high, after rising 19.0% over three months.

The business supports a premium. Return on equity (ROE) was 24.3% in the second quarter of 2026. What has changed since the last note is the runoff polling. Datafolha, AtlasIntel and Ipespe polls taken between 8 October 2026 and 10 October 2026 all show Flávio Bolsonaro ahead of President Lula, and Kalshi priced Bolsonaro's chance of winning at 86% on 6 October 2026.

That makes the vote lopsided for the shares. A Bolsonaro win is largely expected and would mostly confirm the current price. A Lula win would remove the election premium. With the 10-year US Treasury yield above 5.3% as a further headwind, the odds of the shares beating the S&P 500 over the next three months look close to even.

Bullish and bearish views on Itau Unibanco Holding S.A.

The bull case on Itau Unibanco Holding S.A. (ITUB), in brief: Returns remain high. The bear case: The favoured outcome is already priced.

Bull case

• Returns remain high. Itaú reported recurring management profit of R$12.4 billion for the second quarter of 2026, up 7.8% year on year and 1% from the first quarter, with ROE at 24.3% (company results, 4 August 2026; MarketBeat).
• Runoff polls favour the market's preferred candidate. Datafolha showed Bolsonaro at 52% and Lula at 48% on 8 October 2026, AtlasIntel 52.8% to 47.2% on 9 October 2026, and Ipespe 52.7% to 47.3% on 10 October 2026 (The Rio Times). Bloomberg reported Bolsonaro leading the runoff on 9 October 2026.
• Goldman Sachs raised its target. Goldman kept a Buy rating and raised its price target to $10.5 on 9 October 2026 (Benzinga). That is above the $10.16 close the same day.
• The repricing is broad across Brazil. The Ibovespa index closed at a record 206,911.89 on 5 October 2026, up 7.70% in a day, and the US dollar fell more than 4% against the real, trading below R$5 (The Rio Times). A stronger real raises the dollar value of Itaú's real-denominated earnings.
• Loan growth is holding. On the second-quarter call in August 2026, management said loan growth should stay above the midpoint of its guidance, though it may moderate (MarketBeat call summary).

Bear case

• The favoured outcome is already priced. Kalshi put Bolsonaro's chance at 86% on 6 October 2026, and the shares closed at a 52-week high on 9 October 2026. A win that markets already expect leaves limited room for a further jump.
• The margin is narrow. Bolsonaro took 47.07% of valid votes against Lula's 45.12% in the 4 October 2026 first round, with 99.84% counted (Reuters-sourced reports). The three runoff polls show leads of under six points.
• Analysts are split. HSBC cut Itaú to Hold with a $9.1 price target on 8 October 2026 (Benzinga), one day before Goldman's raise. HSBC's target sits below the last close.
• Fee growth guidance was cut. In August 2026 the bank lowered full-year guidance for commissions, fees and insurance growth to 2%–5% from 5%–9% (MarketBeat call summary). Income outside lending is growing slower than planned.
• US rates are a headwind. The 10-year US Treasury yield topped 5.3% on 5 October 2026 and ISM services prices hit a four-year high (Benzinga). Higher US yields tend to pressure emerging-market currencies and equities.

Price setup

The adjusted daily close was $10.16 on 9 October 2026, which is also the 52-week high. The close on 8 October 2026 was $9.83. The shares rose 19.0% over three months, and the 14-day Relative Strength Index (RSI) stood at 73.3 on 9 October 2026; readings above 70 are generally read as overbought.

The nearest published analyst level below the price is HSBC's $9.1 target. Goldman Sachs's $10.5 target is the nearest above it. Moving-average levels are not cited here.

The narrative is accelerating: two analyst moves on 8 October 2026 and 9 October 2026, three runoff polls in three days and a Bloomberg runoff story on 9 October 2026 kept fresh news arriving into a new high. Crowding signs are visible. The RSI is above 70, the price sits at its 52-week high, Itaú was a CNBC "Final Trades" pick on 18 September 2026 and 21 September 2026, and a binary vote and an earnings report fall within the next 26 days. No SEC filings or insider transactions have been reported in the past month.

Catalysts, next 30 days

• 25 October 2026 — Brazil presidential runoff, Lula against Flávio Bolsonaro. The first-round result lifted the iShares MSCI Brazil ETF (EWZ) 13% on 5 October 2026 (Benzinga). The runoff decides whether that repricing holds or reverses.
• 4 November 2026 — Itaú third-quarter 2026 results; conference call 5 November 2026. The report shows whether ROE stays near the 24.3% of the second quarter and whether fee and insurance growth sits inside the lowered 2%–5% range (dates per AJ Bell company calendar).

What would change the view

A Lula win on 25 October 2026 would break the case. It would reverse the political repricing that lifted the Ibovespa to a record on 5 October 2026, and the ADRs would likely give back the gain from $9.83 to $10.16 and more. A daily close below $9.10, matching HSBC's target, would show that the rally has failed whatever the vote.

On the business side, third-quarter ROE below 22% or fee growth running under the 2%–5% guidance range on 4 November 2026 would undercut the premium. The read would improve if Bolsonaro wins and the third-quarter report keeps ROE near 24% with fee growth back inside the range; that combination would give the rally an earnings anchor beyond the vote.

What it trades with

The ADRs trade with Brazilian assets as a group. XP rose 17.2% to $25.2 before the open on 5 October 2026 as EWZ rose 13% the same day (Benzinga), and peers XP, Inter & Co (INTR) and Sabesp (SBS) share the same exposure to the runoff and the real. The ADR also moves with the real against the dollar, so it can diverge from the local B3 listing.

The Emerging markets group has been heating up again since early August 2026, after cooling in late June and July. A cooling group would raise the bar for this name.
