How do I invest and buy/sell stocks?  What does “use a broker” mean?
I'm posting this because I think I can do a better job of explaining and detailing everything from start to stop. :) A "broker" is just someone who connect buyers and sellers - a middleman of sorts who is easy to deal with. There are many kinds of brokers; the ones you'll most commonly hear about these days are "mortgage broker" (for arranging home loans) and "stockbroker". The stockbroker helps you buy and sell stock. The stockbroker has a connection to one or more stock exchanges (e.g. Nasdaq, NYSE) and will submit your orders to them in order to fulfill it. This way Nasdaq and NYSE don't have to be in the business of managing millions of customer accounts (and submitting tax information about those accounts to the government and what-not) - they just manage relationships with brokerages, which is much easier for them. To invest in a stock, you will need to: In this day and age, most brokers that you care about will be easily accessed via the Internet, the applications will be available on the Internet, and the trading interface will be over the Internet. There may also be paper and/or telephone interfaces to the brokerage, but the Internet interface will work better. Be aware that post-IPO social media stock is risky; don't invest any money if you're not prepared for the possibility of losing every penny of it. Also, don't forget that a variety of alternative things exist that you can buy from a broker, such as an S&P 500 index fund or exchange-traded corporate bond fund; these will earn you some reward over time with significantly less risk. If you do not already have similar holdings through a retirement plan, you should consider purchasing some of these sooner or later.
