Sorry if it seems we’re stating the obvious, but you never know! (Remember the person who did everything to set up his new computer—except to plug it in?) Find a good online stock broker and open a stock brokerage account. Even if you already have a personal account, it’s not a bad idea to keep a professional trading account separate. Become familiar with the account interface and take advantage of the free trading tools and research offered exclusively to clients. A number of brokers offer virtual trading. Some sites, including Investopedia, also offer online broker reviews to help you find the right broker.
