Just because your friends are talking up Facebook doesn't mean you should buy it, says Brian Frederick, a certified financial planner at Stillwater Financial Partners in Scottsdale, Ariz. "What might make a great user experience might not make the best investment."
"One of my earliest professional memories was talking to a prospective client who had lost in the six figures by day trading when the Internet bubble burst," he adds.
Financial adviser Warren Ward of Columbus, Ind., puts it this way: "Think twice about buying a stock that's in the headlines. The endorsement of a movie star doesn't guarantee a successful investment."
