Why Is StoneCo Stock Tumbling On Monday? - StoneCo (NASDAQ:STNE)
StoneCo Ltd. (NASDAQ: STNE) fell in premarket trading on Monday after Brazil’s President Luiz Inácio Lula da Silva secured another term, defeating Sen. Flávio Bolsonaro in the runoff. The result reversed expectations for a shift to right-wing leadership, prompting investors to reassess Brazil’s political and fiscal outlook—an effect described as widening the rift between Latin America’s largest economy and U.S. President Donald Trump. Market futures were mixed at the same time, with Nasdaq up 0.09% and S&P 500 futures up 0.15%. Reuters cited positioning for a right-wing win; strategist Luis Felipe Vital and UBS’s Alejo Czerwonko said volatility could increase while investors seek a credible plan to stabilize public debt. StoneCo earnings are due Nov. 12, 2026.
