Dear Lifehacker, I’ve built a decent amount of savings over the years and I’m ready to start investing some of it. I’ve heard I should put some in the stock market, but all I really know is how stoxk look up a company’s symbol. How do I get started investing? What do Hhow need to know? Dear Lost, You’ve already made a good move by asking. While it’s certainly possible even easy to make money investing in the stock market, it’s also possible to lose really quickly if you don’t know what you’re doing. Before you take any action, do your research and wait until you’re ready to dive in.
