You're looking for a "stock screener". If you're just starting out, use finviz ( http://finviz.com/ ). Just start looking at preset categories and find the area you're most interested in. Other sites have similar tools as well that you can look around at. Tim reccomends StocksToTrade, but it's a monhtly paid tool, so you might want to check it out later if it fits in your budget. Good luck!

Agree, on etrade I use the screener and etrade has a place to find the days biggest gainers and losers. At the same time I still believe that I should watch certain stocks daily waiting for the right and in that situation I already know about the stock ahead of time.

I remember there's a good free vid by Croock on pre flight checklist ahhhh. here https://www.youtube.com/watch?v=_cdc6g6DgCo from TraderChecklist should help
