OI S.A.: what insiders have been doing
Every trade that managers of OI S.A. disclose to CVM (Brazil) is tracked on this page. The company sits in the Media sector. Between 25 October 2025 and 25 October 2026, 1 insider published 1 filing.
The filings describe grants, exercises and other transfers rather than trades on the open market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
With 1 filing in twelve months, the company is quieter than the median of 22 filings across the 345 companies we follow on the same exchange. Our records for OI S.A. go back to 2021, with 10 purchases and 1 sale on the open market in total.
Insider buying of OI S.A. has been absent for the past year.
In the same sector, recent insider purchases at Globalstar, Inc. and Liberty Latin America Ltd. also feature in our signals. Source: insider filings from CVM (Brazil). Past trades are no guide to future returns.
