Brazilian Depositary Receipts technical

"Brazilian Depositary Receipts"

Brazilian Depositary Receipts (BDRs) are certificates traded on Brazilian exchanges that represent ownership of shares in foreign companies, allowing local investors to buy and sell exposure to those overseas stocks without opening foreign brokerage accounts. They matter because they let investors diversify across global companies using local currency and trading hours, similar to buying a locally issued voucher for a foreign product, while still exposing portfolios to the performance and risks of the underlying foreign shares.

Cash-Settled Total Return Swap financial

"Cash-Settled Total Return Swap"

weighted average price financial

"The price reported is a weighted average price"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
