NYSE (New York Stock Exchange)

The largest stock exchange in the world by total market capitalization of listed companies, tracing its history back to the Buttonwood Agreement signed by 24 stockbrokers under a buttonwood tree on Wall Street in 1792. The NYSE is known for its hybrid model that combines electronic trading with a physical trading floor, where designated market makers (DMMs) help maintain orderly markets in assigned stocks. It is home to many of the world's most prominent companies and remains a symbol of American capitalism.
