The two primary stock exchanges in the United States are?

The two primary stock exchanges in the United States are the New York Stock Exchange (NYSE) and the NASDAQ. The NYSE is known for its physical trading floor and is one of the largest stock exchanges by market capitalization, while NASDAQ operates as a fully electronic marketplace. Both exchanges play crucial roles in facilitating the buying and selling of stocks, providing liquidity to the market, and offering investors a platform to invest in publicly traded companies.

The NYSE has a long history, traditionally hosting large, well-established companies, whereas NASDAQ is known for its technological innovation and listing many tech giants. Together, they account for a significant portion of the stock market activity in the United States. This combination of electronic and physical trading venues reflects the diversity of investment opportunities available to investors.

Other options include entities that do not fit the criteria of stock exchanges. For instance, the SEC, or Securities and Exchange Commission, is a regulatory body and not an exchange itself. The Nikkei is an index representing stocks on the Tokyo Stock Exchange in Japan and is therefore not relevant in the context of primary stock exchanges in the United States.
