New York Stock Exchange (NYSE) Explained
What Is the NYSE?
The NYSE traces its origins to the Buttonwood Agreement of May 17, 1792, when 24 stockbrokers and merchants signed an agreement under a buttonwood tree on Wall Street. It formalized as an exchange in 1817 and has operated continuously ever since — surviving wars, panics, the Great Depression, 9/11, and the 2008 financial crisis.
Today the NYSE is owned by Intercontinental Exchange (ICE), which acquired it in 2013. It lists approximately 2,400 companies including some of the world’s largest: Berkshire Hathaway, JPMorgan Chase, ExxonMobil, Johnson & Johnson, Walmart, and Procter & Gamble. The majority of Dow Jones and S&P 500 components are NYSE-listed.
How Does NYSE Trading Work?
The NYSE uses a hybrid model combining electronic trading with human Designated Market Makers (DMMs) on the trading floor. While most orders are matched electronically, DMMs are responsible for maintaining fair and orderly markets in their assigned stocks — stepping in to provide liquidity when buy and sell orders are imbalanced.
The iconic trading floor at 11 Wall Street remains operational, though the vast majority of volume flows through electronic systems. The opening bell at 9:30 AM ET and closing bell at 4:00 PM ET are daily rituals broadcast worldwide.

The Role of the NYSE in Capital Markets
The NYSE is more than a stock exchange — it’s a capital formation engine. Companies go public on the NYSE to raise capital, gain visibility, and establish credibility. The exchange has hosted some of the largest IPOs in history, including Alibaba ($25 billion in 2014), Saudi Aramco’s secondary listing consideration, and numerous major SPAC listings.
For investors, NYSE-listed stocks benefit from deep liquidity, tight bid-ask spreads, and the oversight of NYSE regulation — providing an extra layer of market quality on top of SEC regulation.

Frequently Asked Questions
What is the difference between the NYSE and the stock market?
The NYSE is one exchange — a venue where stocks are bought and sold. “The stock market” is a broader term encompassing all exchanges (NYSE, Nasdaq, Cboe, etc.) and the overall activity of publicly traded securities. When people say “the stock market went up,” they usually mean major indexes like the S&P 500, which includes stocks from multiple exchanges.
Can anyone buy stocks on the NYSE?
Yes — any investor with a brokerage account can buy and sell NYSE-listed stocks. You don’t need to be on the physical trading floor. Brokers route your orders electronically to the exchange, where they’re matched with counterparties in milliseconds.
What happens when the NYSE opens and closes?
At 9:30 AM ET, an opening auction matches all pre-market orders accumulated overnight to set opening prices. At 4:00 PM ET, a closing auction determines the official closing prices — the ones quoted on financial news. The closing auction is the single most important price-setting event of the day, processing billions of dollars in volume.
Can a company switch from Nasdaq to NYSE?
Yes. Companies can and do switch exchanges. High-profile transfers include Texas Instruments (Nasdaq to NYSE) and others. The move typically involves meeting the target exchange’s listing requirements, paying listing fees, and coordinating the technical transfer — usually completed over a weekend.
What are circuit breakers on the NYSE?
Circuit breakers are market-wide trading halts triggered when the S&P 500 declines by 7% (Level 1), 13% (Level 2), or 20% (Level 3) from the prior day’s close. Level 1 and 2 halt trading for 15 minutes. Level 3 halts trading for the rest of the day. These were triggered on four separate days in March 2020 during the COVID sell-off.
