Frequently Asked Questions

Why hold PRIO (Petro Rio) PTRRY ADR instead of local B3 PRIO3 shares?

Buying directly on Brazil’s B3 exchange means opening a local brokerage account, converting currency and dealing with Brazilian tax paperwork. ADRs remove that friction: they settle in dollars, follow US market hours, and report in formats foreign investors already understand.

The trade-off is that an ADR’s price reflects two moving parts: (1) the underlying share price, quoted in reais on the B3, and (2) the USD/BRL exchange rate. Because of that second part, a rising company can still deliver a flat, or even negative, dollar return if the real weakens against the dollar. The same applies to ETFs: funds such as EWZ, EWZS and FLBR bundle dozens of these companies into a single ticker for instant diversification, but their dollar value still moves with the real.

Where is PRIO (Petro Rio) listed?

PRIO (Petro Rio) trades on 2 exchanges. The line quoted on this page is OTC in the United States (PTRRY, US dollars). It also trades on B3 (São Paulo) in Brazil (PRIO3, Brazilian reais).

On how many exchanges does PRIO (Petro Rio) trade?

2. OTC — PTRRY (USD) · B3 (São Paulo) — PRIO3 (BRL). Prices shown on this page are the OTC line, PTRRY.

What is PRIO (Petro Rio)'s primary listing?

PRIO (Petro Rio)'s primary listing is on the B3 in Brazil, where the shares trade as PRIO3 in reais — the company's home market. The OTC line quoted on this page is an ADR over those same shares: it gives you the asset in US dollars, on US market hours, without opening a Brazilian brokerage account or trading in reais.

What is the difference between PTRRY and PRIO3?

They are the same company and, economically, the same asset. PRIO3 is the original Brazilian share, listed on the B3 and quoted in reais. PTRRY is an American Depositary Receipt over that share, listed on the OTC and quoted in US dollars — a wrapper whose purpose is to give foreign investors access to the Brazilian asset without opening an account in Brazil. The PTRRY price therefore tracks two things: PRIO3 in reais, and the USD/BRL exchange rate.

How can I buy PRIO (Petro Rio) stock in the United States?

PRIO (Petro Rio) is listed on the OTC under PTRRY, priced in US dollars. Any US brokerage offering over-the-counter securities can trade it, with no foreign-account paperwork and no currency conversion.
