Stock Exchanges: NYSE, NASDAQ, and Global Markets
A stock exchange is a regulated marketplace where shares are listed, quoted, and traded. Exchanges don't own your shares — they provide the infrastructure that matches buyers with sellers and publishes prices in real time.
Major US Exchanges
- NYSE (New York Stock Exchange) — The oldest and largest US exchange. Known for blue chip and established industrial companies. Uses a hybrid auction model with designated market makers.
- Nasdaq — Founded in 1971, fully electronic. Home to many technology and biotech firms (Apple, Microsoft, Nvidia).
- NYSE American / Arca — Smaller-cap and ETF-focused venues operated by NYSE.
How Exchanges Work
Every exchange maintains an order book of buy (bid) and sell (ask) orders. Trades match by price-time priority: the best price fills first, and the earliest order at that price wins.
Exchanges also:
- Set listing requirements (revenue, share price, number of shareholders)
- Disclose corporate filings and news
- Suspend trading during extreme volatility (circuit breakers)
- Collect and publish trade data

Listing vs. Trading
A company lists on one exchange but its shares can trade on others through cross-listing or ADRs. Alibaba, for example, is listed in Hong Kong and New York.
Why Exchanges Matter to Traders
The exchange affects:
- Liquidity — Bigger exchanges usually mean tighter spreads
- Trading hours — Each exchange follows local market hours
- Regulation — Rules differ by country and exchange
- Tax treatment — Foreign listings may carry withholding tax on dividends
For beginners, sticking to liquid US-listed stocks during regular session hours (9:30–16:00 ET) gives the cleanest fills and fewest surprises. Once you understand the basics, global exchanges open up a wider world of opportunity — and a wider set of rules to learn.
