American Depositary Receipts (ADRs) financial
"876,317 American Depositary Receipts (“ADRs”)"
American depositary receipts (ADRs) are certificates issued by a U.S. bank that represent ownership of shares in a foreign company, letting those shares trade on U.S. exchanges in U.S. dollars. Think of an ADR as a U.S. receipt for a foreign stock: it makes buying and selling simpler and subjects the investment to familiar U.S. trading rules, which matters to investors because it improves access and liquidity while still carrying risks like currency moves and different dividend handling.
