Domestic shares
Rules, protection and tax below are for Brazil.
What it is
Part ownership of a company. A share entitles you to a slice of the profits the company chooses to pay out, called a dividend, and to a vote at its meetings. Its price on the exchange is what other people will pay today for that slice of the future.
Over decades, owning a broad spread of companies has been the most reliable way ordinary people have grown money faster than inflation. Owning one or two companies is a different activity: the outcome depends on those particular businesses, and plenty of once-solid names have gone to nothing.
Shares in your own country are the easiest to buy, cheapest to hold and simplest for tax. They also mean your job, your house and your investments all ride the same economy.
How it works
- You open an account with a broker, which holds the shares for you and executes your orders on the exchange.
- You pay the price on screen plus the spread, any commission, and in some countries a purchase tax.
- Dividends land in your account when the company pays them; you can take them or reinvest.
- You sell whenever the market is open, at whatever the price is then, and any gain may be taxed.
The honest pros and cons
For
- The highest long-run returns of the mainstream asset classes, historically.
- Cheap to buy and hold, with no fund fee at all.
- Dividends give an income that has tended to grow over time.
- You can sell in seconds on any trading day.
Against
- Single companies fail; a concentrated holding can lose everything.
- Prices fall 30 to 50 percent in bad years, and you have to be able to sit through that.
- Picking winners is much harder than it looks; most people underperform a plain index fund.
- Everything you own may already depend on your home economy, so more of it adds no diversification.
Getting it in Brazil
Domestic shares available
- Account type: Conta em corretora (brokerage account)
Wherever you are
- Open a brokerage account, preferably inside whatever tax shelter your country offers.
- Decide whether you are buying a few companies you understand or a broad spread; if it is the spread, an index fund does it for you cheaply.
- Set a limit on how much of your total money sits in any one company; 5 percent is a common ceiling.
- Buy, record the price for tax, and stop looking at it every day.

Getting it from another country
Via United States allowed· available there
Open an account with a US broker that accepts Brazilian residents (several do, fully online) and send money through an authorized exchange operation, which itself costs a spread and a transaction tax.
What you gain
- Direct ownership of US shares and ETFs in dollars, a far wider menu than the BDRs listed on B3.
- A deliberate dollar holding, which many Brazilians want as a counterweight to real weakness.
- US trading costs are among the lowest anywhere.
What you give up
- Currency risk cuts both ways: a stronger real shrinks dollar gains the day you convert back, and every transfer pays a spread plus IOF tax.
- US withholding tax of 30 percent on dividends, with no treaty between Brazil and the US to reduce it.
- Income and gains from abroad are taxed in Brazil under the foreign-investment rules that took effect in 2024, declared in the yearly return.
- Holdings abroad must be declared to the Receita Federal every year and to the Central Bank above thresholds.
- No FGC. US broker protection covers a broker failing, never a market loss.
- Protection there: SIPC protects up to 500,000 dollars of securities per customer if the broker fails, including 250,000 in cash; it does not cover losses in value (source, checked 2026-09-10)
- Tax: income and gains from investments abroad are taxed in Brazil at the flat rate set by the 2024 foreign-investment rules and reported in the annual return; holdings above thresholds are also declared to the central bank (source, checked 2026-09-10)
Currency reality check
The same BRL 1,000 left for 10 years, at each country's savings rate:
Kept in BRL at about 9.5% a year
BRL 2,454
Sent to USD at about 2.5% a year, the account would show
USD 393 the tempting number
Brought back to BRL after the exchange rate moved 67.2%
BRL 2,136 what you can actually spend
Before tax, before fees, and before the risk that the exchange rate does something quite different next time. A higher rate abroad is only a higher return once it has survived the conversion back.

Often confused with
- Corporate bond: A loan to a company that pays interest; riskier than lending to a government because companies fail more often.
- Foreign shares: Part ownership of a company listed in another country; currency moves affect your return too.
- Stock index ETF: A fund traded on an exchange that copies a stock market index at low cost.
