Ranked exposures

  1. ▼ PBR Petrobras — impact -79 · confidence medium · horizon immediate · 1st order
    Fuel price controls reduce Petrobras's refining margins and cash generation by keeping domestic prices below import parity.
    Chain: Lula leads first round vote count → market prices higher odds of interventionist fuel policy → domestic pump prices held below import parity → refining and marketing margin per barrel compresses → dividend capacity and free cash flow fall
    What would break the call: Petrobras reaffirms its market-linked pricing policy and keeps the variable dividend formula unchanged after the vote.
  2. ▼ CIG Cemig — impact -72 · confidence low · horizon immediate · 2nd order
    A Lula victory raises expectations of tariff restraint and social investment demands depressing Cemig's regulated distribution margins.
    Chain: Lula first round win signals policy continuity → regulator faces pressure for tariff moderation → Cemig distribution tariff reviews turn less generous → allowed revenue and regulated EBITDA growth slow → state of Minas privatization optionality fades
    What would break the call: ANEEL grants Cemig a full inflation pass-through in its next tariff review.
  3. ▲ SUZ Suzano — impact +68 · confidence high · horizon immediate · 2nd order
    A weaker real widens Suzano's export margins because pulp sales are dollar-priced while mill costs remain local.
    Chain: election result pressures fiscal risk premium → real depreciates against the dollar → pulp revenue stays dollar priced → mill cash costs remain in reais → export EBITDA margin per tonne widens
    What would break the call: The real strengthens after the vote as foreign inflows return to Brazilian assets.
  4. ▲ VALE Vale — impact +64 · confidence medium · horizon immediate · 2nd order
    Currency depreciation lifts Vale's real-denominated margins because iron ore sales are mainly priced in dollars.
    Chain: fiscal uncertainty weakens the real → iron ore priced in dollars → Brazilian mining costs denominated in reais → C1 cash cost per tonne falls in dollars → margin and dividend capacity improve
    What would break the call: Iron ore prices drop below seventy dollars as Chinese steel output contracts.

    What would break the call: The regulator confirms Sabesp's tariff trajectory and efficiency sharing rules unchanged.
  8. ▼ ITUB Itau Unibanco — impact -51 · confidence medium · horizon immediate · 2nd order

    What would break the call: The central bank begins a clear easing cycle and Itau guides provisions lower.
  9. ▼ BBD Bradesco — impact -50 · confidence medium · horizon immediate · 2nd order

  10. ▲ JBS JBS — impact +50 · confidence low · horizon quarters · 2nd order

    Chain: political risk premium weakens the real → beef and poultry exports priced in dollars → Brazilian cattle and labor costs stay in reais → processing spread per head widens → Seara and Brazil beef EBITDA rises
    What would break the call: Brazilian cattle prices spike on tight supply and erase the processing spread.
  11. ▼ NU Nu Holdings — impact -49 · confidence medium · horizon weeks · 2nd order

    What would break the call: Nubank posts accelerating interest earning portfolio growth with stable fifteen to ninety day delinquency.

  15. ▼ BSBR Santander Brasil — impact -44 · confidence low · horizon immediate · 2nd order
    Santander Brasil earns nearly all revenue domestically, so a weaker real and softer credit demand cut dollar profits.
    Chain: fiscal risk premium keeps Brazilian rates elevated → retail credit demand and asset quality worsen → Santander Brasil provisions rise → real depreciation shrinks dollar reported earnings → ADR value falls on both channels
    What would break the call: The real rallies and Santander Brasil guides to lower provisions next quarter.

  18. ▲ AGRO Adecoagro — impact +38 · confidence medium · horizon weeks · 2nd order

    What would break the call: Global sugar and grain prices fall enough to offset the currency benefit.
