The first thing you should know is that investing in stocks involves risk and can be volatile. You should also understand how the stock market works, including how companies are valued and what factors influence their share prices. Additionally, it’s important to research the different types of investments available, such as mutual funds and ETFs, so that you can make an informed decision about which ones are right for you.
