A more thorough explanation:

A securities exchange is a place where people can buy and sell stocks and other securities. It's like a marketplace for investments. There are different types of securities exchanges, including regional exchanges that focus on local stocks and bonds.

• The New York Stock Exchange (NYSE) is a well-known securities exchange where people can buy and sell stocks of companies like Apple, Microsoft, and Coca-Cola.
• The Boston Stock Exchange is a regional securities exchange that focuses on stocks and bonds of local interest, such as companies based in Boston or the New England area.

These examples illustrate how securities exchanges work. Investors can buy and sell stocks and other securities through these exchanges, which provide a centralized and organized marketplace for trading. The NYSE is a large exchange that offers a wide range of stocks from different companies, while regional exchanges like the Boston Stock Exchange focus on local investments.
