US-Listed Brazilian Stocks Premarket: 5 Movers as First-Round Vote Reprices Election Risk

Key Highlights

  • The iShares MSCI Brazil ETF (NYSE Arca:EWZ) is indicated 12.07% higher premarket at $42.80.
  • Flavio Bolsonaro took 47.1% of valid votes against 45.1% for President Lula, with a runoff due on October 25.
  • Inter & Co, Inc. (NASDAQ:INTR) leads the group with a 16.45% indicated gain, on thin volume.
  • The Brazilian real firmed below 5.00 per US dollar, a 17-month high.
  • The runoff, Brazil's public debt and elevated US yields remain the main risks to the rally.

Brazilian equities listed in the United States opened the week sharply higher on October 5. The first-round presidential result beat the poll average tracked by Goldman Sachs by more than four percentage points for Bolsonaro. Investors appear to be pricing a higher probability of fiscal discipline and a more business-friendly policy mix. US index futures were broadly flat to modestly higher, which suggests the move is specific to Brazil. All figures below are premarket indications from around 8:50 AM EDT, not official closes.

1. Inter & Co, Inc. (NASDAQ:INTR): +16.45%

Shares are indicated at $6.38, against a $5.48 close on October 2. Market capitalisation stands at $2.42 billion, with a trailing price-to-earnings ratio of 7.81 and a dividend yield of 2.06%. The stock remains well below its 52-week high of $10.36. Premarket volume of 4.16 million shares is light, so the move could reverse as liquidity builds.

2. Itau Unibanco Holding S.A. (NYSE:ITUB): +14.92%

The ADR is indicated at $9.87, up from $8.59, and above its 52-week high of $9.60. Market capitalisation is $94.68 billion, trailing price-to-earnings is 11.07 and the dividend yield is 7.06%. Second-quarter recurring net income reached BRL 12.4 billion, up 7.8% year over year, with a return on equity of 24.3%. The bank is Brazil's largest privately held lender, so it is a natural proxy for domestic credit sentiment.

3. Banco Bradesco S.A. (NYSE:BBD): +13.70%

Shares are indicated at $4.15, compared with a $3.65 close, and sit just below the 52-week high of $4.30. Market capitalisation is $38.60 billion, trailing price-to-earnings is 7.45 and the dividend yield is 6.69%. Several executives and a director bought shares around September 18, in amounts of roughly $0.9 million to $2.35 million each. Two details complicate the read-through: October 5 is the ex-dividend date, which adjusts the quoted price, and second-quarter adjusted earnings per share missed consensus by about 4%. Third-quarter results arrive on October 22, three days before the runoff.

4. Nu Holdings Ltd. (NYSE:NU): +12.29%

The digital bank is indicated at $15.08, up from $13.43. Market capitalisation is $65.04 billion and trailing price-to-earnings is 18.15, the richest multiple in this group. The stock pays no dividend and trades below its 52-week high of $18.98. Second-quarter net income rose 49% to $1.1 billion, and risk-adjusted net interest margin expanded to 12.4%. The 90-plus-day non-performing loan ratio of 6.9% is the metric to monitor. The next earnings report is due on November 12.

5. iShares MSCI Brazil ETF (NYSE Arca:EWZ): +12.07%

The fund is indicated at $42.80, against a $38.19 close, which puts it above its 52-week high of $42.02. Volume of 59.88 million shares is already heavy, and the fund holds $7.66 billion in market capitalisation. EWZ tracks the MSCI Brazil 25/50 Index, with Nu Holdings, Vale S.A. (NYSE:VALE), Itau Unibanco and Petrobras (NYSE:PBR) among its largest holdings. A Frankfurt-listed MSCI Brazil ETF gained more than 14% at the open, which points to demand beyond US-listed vehicles.

What Could Unsettle the Rally

The first round settled little. The runoff will turn on debate performances, voter mobilisation and how supporters of eliminated candidates vote. Brazil's high public debt and rigid spending rules mean that even a favourable outcome would deliver reform slowly.

The external backdrop is less supportive. The US 10-year Treasury yield has hovered near 5.25% after the Federal Reserve raised rates in September, and Brent crude is above $100 a barrel. The Financial Select Sector SPDR Fund (NYSE Arca:XLF) fell 2.5% last week. Minutes of the latest Federal Open Market Committee meeting are due on Wednesday and may shift global risk appetite.

Premarket gains of 12% to 16% in large banks are unusual, and they carry reversal risk if the runoff polling tightens or global yields climb further. This article is informational and does not constitute investment advice.

Q: Which Brazilian stock has the largest premarket gain? A: Inter & Co (NASDAQ:INTR) leads at 16.45%, followed by Itau Unibanco (NYSE:ITUB) at 14.92%. INTR's premarket volume is thin, so its move may be less reliable.
