With shares of Facebook expected to begin trading later this week, you may be among the 900 million active users looking to get a piece of the action. But before you hit the buy button there are a few things you should know.

Apple, maker of the wildly popular iPhone and iPad, leapt across the $500 billion mark in terms of market capitalization on Feb. 29, 2012, for the first time in its history. Its stock price – well past the $500-per-share threshold – continues to set new highs, seemingly on a regular basis. It appears to be headed toward $600 and beyond, with the release of the iPad 3 and the iPhone 5. But if the stock seems too expensive, here are other ways to play an Apple rally. — Bruno J. Navarro

This year’s ready-to-wear fall fashion collections are being unveiled at  New York Fashion Week. "Fast Money" traders look at how to work the sector.

Do Wall Street pros know something the rest of us don’t? Why are billionaire investors ahead of the curve, while most individual investors are behind it? According to trader Joe Terranova, it’s because money pros regularly employ strategies that regular folk don’t even know exist.

‘Stick with what’s working.’ Money pros have been saying it for quite a while.  In other words, when you put money to work pick stocks that are leaders not laggards – buy high and sell higher; that’s the trade that has paid.  However, with some leaders advancing 50% or more over a period of only 1 year, investors are starting to wonder how much upside can possibly be left.  Given the outperformance, should you remain bullish on these S&P over achievers? Or is the trading thesis getting a little long in the tooth?

Does the market seem almost schizophrenic to you? One day euphoria sends stocks surging, then the very next day fear sends investors running for the exits. Sick of it? We are, too.
