Top developments
Ibovespa Plunges 13.88% After Election Shock
On Monday, October 26, the Ibovespa index plummeted 13.88% to close at 176,608 points, marking the worst daily performance since 1994. The sharp decline was driven by investor panic over Lula's re-election, which triggered a circuit breaker and suspended trading for 30 minutes. In dollar terms, the index lost 21.13%, reflecting a severe devaluation of Brazilian assets amid political uncertainty.
Petrobras Loses $24 Billion in Market Value
Petrobras shares were among the hardest hit, losing US$24.2 billion in market value on October 27, the day after the election results. The state-controlled oil giant faced intense selling pressure as investors feared increased government intervention in pricing and capex policies. Despite the massive loss, Petrobras fell less than the broader market average, indicating some defensive positioning by long-term holders.
Bank Shares Drive Wednesday's 2.68% Decline
After a brief stabilization on Tuesday, the Ibovespa fell 2.68% on Wednesday, October 28, closing at 171,006 points. The decline was led by bank shares, which slid amid concerns over credit risk and regulatory changes under the new administration. The real held steady near R$5.35 per dollar, suggesting currency markets are beginning to digest the initial shock.

Valor Investe Questions "Buy the Dip" Strategy
Local media outlets are increasingly skeptical of traditional "buy the dip" strategies. Valor Investe reported that the Ibovespa is flirting with its lowest level since August, putting the "caiu, comprou" (fell, bought) thesis in check. Analysts note that foreign investors have withdrawn R$7 billion, creating a vacuum that may lead to further drops toward 164,000 points.

Foreign Investor Outflows Accelerate
