I looked at the sector map at SmartMoney. Yes, it's interesting but fancy colors are not going to make me money. No Michael, only you can make you money. I've never stumbled across a decent sector heat map, especially a realtime one. The map at Smart Money is interesting it that it gives you the relative size of the various players within about a dozen sectors, and if you click on a particular company there's a drop-down menu that will provide additional info. Frankly it seems better suited to swing traders or short-term position traders. Then again, for true sector-based trading I think Hitman's setup and methodology is the way to go.
