About Petro Rio S.A.

Petro Rio, which operates as PRIO, is a Brazilian independent oil and gas company based in Rio de Janeiro. It focuses on acquiring and redeveloping mature offshore oil fields, mainly in the Campos Basin, and produces crude oil that it sells into domestic and international markets. Its activities span exploration, development and production of oil and natural gas, with a business built around reviving existing fields rather than large new frontier projects.

The shares are listed on the B3 Stock Exchange in Brazil under the code PRIO3, and the price on this page is in Brazilian reais (BRL). Our dividend records, which start in 2019, show payments in one calendar year. The Market X-Ray on this page is price-based and compares it with other stocks on the same exchange; it does not measure how healthy the business is.

Signals describe what the chart is doing, not what to do. Moving averages: price above the average is bullish. Oscillators use the usual thresholds (RSI 30/70, Stochastic 20/80, CCI ±100, Williams %R −80/−20; MACD and momentum above zero are bullish). Weekly and monthly views use closing prices only.
