Shares of Brazilian agro-retail firm 3tentos (TTEN3) plunged 16.01% on July 28, closing the session at R$12.80, after the company became the subject of an inquiry by the *Comissão de Valores Mobiliários* (CVM), the country's securities regulator. The significant drop in the B3-listed stock was triggered by reports suggesting the company’s investor relations department shared preliminary Q2 2026 results and revised projections with sell-side analysts, which constitutes a potential breach of market rules on selective disclosure of material information.
