ADRs financial

"Number of Shares / ADRs"

American Depositary Receipts (ADRs) are certificates issued by a U.S. bank that stand in for shares of a foreign company, allowing those shares to be bought and sold on U.S. stock exchanges in U.S. dollars. Think of an ADR as a local ticket representing a foreign stock: it makes trading, settlement, and tax reporting simpler for U.S. investors, but still exposes them to risks like currency moves, different accounting rules, and foreign corporate practices.

average daily trading volume financial

"25% of the average daily trading volume"

The average daily trading volume is the typical number of shares or units of a security that change hands each trading day, calculated over a set period. It tells investors how active a market is—like average traffic on a road—so higher volume usually means easier, faster trades and smaller price swings when buying or selling, while low volume can make orders harder to fill and cause bigger price moves.

par value financial

"with a par value of $1 (one Peso)"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.
