NYSE
The world's largest stock exchange by market capitalization, located at 11 Wall Street in New York City.
The New York Stock Exchange (NYSE) is the world's largest equities exchange by total market cap of its listed companies. Founded in 1792, it operates a hybrid model combining a physical trading floor with electronic execution.
NYSE-listed stocks use 1–3 letter tickers and tend to be large, established companies: Berkshire Hathaway (BRK), JPMorgan (JPM), ExxonMobil (XOM). Listing requirements include minimum market cap, shareholder count, and earnings thresholds.
The NYSE's Designated Market Maker (DMM) system assigns a human or electronic specialist to each listed stock to maintain orderly markets, facilitate openings and closings, and provide capital in volatile conditions.
