4 terms

Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Brazilian depositary receipts financial

"Brazilian Depositary Receipts are certificates representing Common Shares"

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.

Open Market Purchases financial

"12/15/2022 | Open Market Purchases | Shares were acquired"

Open market purchases are buys of a company’s shares (or other securities) made on public exchanges at prevailing market prices rather than through private deals. For investors this matters because when a company buys back its own stock it reduces the number of shares available, which can boost per-share earnings and often signals management’s confidence; it also affects supply, demand and short-term liquidity much like someone quietly buying up items from a crowded marketplace.
