➤ Understanding the Stock Market
The stock market is like a place where people buy and sell pieces of companies. It helps find the right prices for these company shares and shows how well the economy is doing. It’s a fair and open place where buyers and sellers compete, and everyone can easily buy or sell.
Long ago, in 1773, the London Stock Exchange started in a coffeehouse where traders met to trade shares. Then, in 1790, the first U.S. stock exchange began in Philadelphia. Wall Street in New York City began with an agreement signed by 24 traders under a buttonwood tree in 1792. They later called it the New York Stock and Exchange Board.
The stock market is controlled and watched over. In the U.S., the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) make sure things are fair.
In the past, people used paper certificates to trade. Now, stock markets work electronically.

➤ How the Stock Market Works
Stock markets are safe places where people can buy and sell shares and other financial things with confidence. They follow rules set by regulators to make sure things are fair and safe.
Companies use the stock market to sell their shares to the public for the first time. This is called an initial public offering (IPO). It helps companies get money from investors. Companies divide themselves into shares and sell them to the public at a price per share.
Later on, companies can also sell more shares or even buy back their shares. Investors buy shares, hoping their value will go up, and they might get paid dividends.
The stock exchange helps with this process and gets paid for its help. People can also buy and sell things they already own in the stock market.
The stock market keeps track of how well the market is doing with indicators like the S&P 500 index and the Nasdaq 100 index.
➤ Functions of a Stock Market
The stock market does important things like making prices clear, helping trades happen easily, finding fair prices, and making sure things are done fairly.
The stock market makes sure that everyone can see the prices for buying and selling things, so prices are fair. It also helps match people who want to buy with people who want to sell.
The stock market figures out fair prices by looking at what everyone is willing to pay and sell for. People who trade on the stock market include those who hold stocks for a long time, those who quickly buy and sell, and those who provide liquidity or trade in things related to stocks.
➤ How Stock Markets Are Regulated
In different countries, there are stock markets, each watched over by a local financial authority. In the U.S., the SEC is in charge of overseeing the stock market.
The SEC is a separate agency from the government that’s focused on safeguarding investors, keeping markets fair, orderly, and efficient, and supporting capital formation.
Companies listed on stock exchanges are regulated by the SEC. Exchanges also set rules, like requiring companies to report their financial info on time and quickly share important news. Not following these rules can lead to trading being stopped and other punishments.
