how does the stock market work
The stock market is a financial marketplace that connects buyers and sellers to trade shares of public companies, allowing businesses to raise capital and investors to potentially grow their wealth.
The stock market is a network of exchanges and platforms where investors buy and sell shares of publicly traded companies. It functions through two main stages: the primary market, where companies first issue shares to raise capital, and the secondary market, where investors trade existing shares among themselves. Prices are determined by supply and demand, a process known as price discovery, where buyers and sellers negotiate based on company performance, economic conditions, and market sentiment. Most trading today occurs electronically through brokerage accounts, which act as intermediaries between individual investors and the exchanges.
- Primary and Secondary Markets. Companies issue shares in the primary market to raise capital for growth. Once issued, these shares are traded between investors in the secondary market, where the company is no longer directly involved.
- Supply and Demand. Prices fluctuate based on supply and demand. When more people want to buy a stock than sell it, the price typically rises; when supply exceeds demand, the price typically falls.
- Trading and Price Discovery. Investors use brokerage accounts to place orders. A bid is the highest price a buyer will pay, while an ask is the lowest price a seller will accept. A trade occurs when these prices align.
- Exchanges and Indices. Exchanges like the NYSE or Nasdaq provide the infrastructure for trading, ensuring transparency and compliance with regulations, while indices track the performance of specific groups of stocks.
