How does the stock market work?
assistant
The stock market is a place where buyers and sellers of securities can trade. Securities are financial instruments such as stocks, bonds, or other debt obligations that represent ownership in a company. When you buy a security, you are essentially buying a piece of that company. When you sell a security, you are essentially selling a piece of that company. The price of a security is determined by supply and demand. If there is more demand for a security than supply, its price will go up. If there is more supply than demand, its price will go down.
