The two primary stock exchanges in the United States are the New York Stock Exchange (NYSE) and NASDAQ. The NYSE is one of the oldest and most prestigious stock exchanges, known for its physical trading floor located on Wall Street in New York City. It features a wide range of large, established companies across various sectors.

NASDAQ, on the other hand, is notable for its electronic trading platform and is known for hosting many technology and internet-based companies. It operates without a physical trading floor, allowing for faster and more efficient trading.

Both exchanges are integral to the U.S. financial markets, providing platforms for buying and selling shares of publicly traded companies and facilitating capital formation. This combination of traditional (NYSE) and modern (NASDAQ) trading reflects the diverse landscape of investment opportunities available to investors.

The other options contain exchanges or indices that are not primary stock exchanges in the U.S. For example, the Dow Jones is a stock market index rather than an exchange, and the Nikkei is the primary index for the Tokyo Stock Exchange in Japan.
