B3 S.A. Brasil, Bolsa, Balcão shares delivered a 47.58% total return over 25 months after InvestingPro flagged the stock as undervalued in April 2024, according to the platform’s latest review published on August 23, 2026.
The São Paulo-based exchange operator’s shares climbed from an entry price of R$11.18 to a fair-value target of R$15.00—representing 34% upside at the time—before reaching R$16.50 by May 2026. InvestingPro has since raised its fair-value estimate to R$21.42, implying an additional 29.8% potential gain.
The appreciation followed a sharp 10% drop in April 2024, which InvestingPro identified as a mispricing opportunity. Fundamental metrics corroborated the thesis: revenue rose 17% to R$2.08 billion in mid-2026 from R$1.78 billion in April 2024, while EBITDA increased 31% to R$1.40 billion. Earnings per share jumped 44% to R$0.2032 over the same period, with Q1 2026 EPS up 39% year-over-year.
Quarterly performance showed continued momentum: Q4 2025 revenue grew 11% and EBITDA margins expanded to 69%, up from 60% in the baseline period. InvestingPro’s methodology combines discounted cash flow, peer comparisons, and dividend discount models, supplemented by analyst consensus and a built-in safety margin.
The platform’s ProPicks tool, which uses AI-driven portfolio selections, contributed to the identification of B3 as an undervalued asset. Recent downgrades from Goldman Sachs and UBS cited competitive pressures, yet InvestingPro’s fair-value model and underlying fundamentals remained aligned with the stock’s upward trajectory.
