Picking any stock is easy, picking stocks that will make money is difficult. Investing in the stock market is a good way to make money. Investing may or may not give you a higher return than your bank account. There is the risk of losing all your investment. Investing is also a good way to learn about how stocks, bonds and mutual funds work as well as learn about how corporations work.
Research is the key to picking a good stock.
One way of doing research is to go to the local mall. When walking around the mall watch the shoppers, where they go and what they buy. If the company is public, do research, use the internet, newspapers and magazines, to find information about the company. It is also a good idea to call the company and see if they will send you an investors package. If the company is private, you're out of luck.
