Why is StoneCo stock collapsing today?

StoneCo (STNE) shares fell 34.7% in pre-market trading after Brazil's President Lula won re-election, surprising markets. Investors had expected a Bolsonaro win, which would have favored tighter fiscal policy. StoneCo's decline reflects concerns about higher interest rates and a weaker revenue outlook under Lula's administration. The stock dropped to $7.50, below its 52-week low of $8.95. The broader U.S. market remained flat, indicating the move was driven by Brazil-specific factors.
