Stock market is not doing real well, if you still want to go for it. Bio-tech is probably the way to go. Invest in the stem cell companies if you want to play the game. However don't play with stocks unless you have money to play with. You can always stay conservative and put your money in a interest maximizer or CD.
I used to be a broker and now trade for myself.
My advice to you is to use Interactivebrokers.com as the commisions are only .01 per share which is about as good as it gets.
I'm mainly a technical trader meaning i use charting software versus a fundamental trader who uses balance sheets, quarterly earnings etc..
If you don't have a firm grasp on what your doing then don't.
I hate to say it but you can't go wrong with real estate even now.
