An Investment Account is a type of financial account that allows individuals to buy and sell various investment products, such as stocks, bonds, and mutual funds. These accounts can be opened at financial institutions like banks or brokerage firms, and they provide a platform for managing investments and tracking their performance over time. Investment accounts can be categorized into different types, including taxable accounts and tax-advantaged accounts like Individual Retirement Accounts (IRAs). Each type has its own rules regarding taxes and withdrawals, making it important for investors to choose the right account based on their financial goals and needs.
