All very good points but if one plays these bullish sectors properly than money can be made. If you follow the likes of Dines or anyone else blindly then one should not even consider these markets. However if one uses Dines and others that can pop the market and play the game properly then a lot can be made. Unfortunately people get into bullish sectors near the top long after "smart"  money is gone. Mark my words..FDR should pop, maybe a good double from here, then people who bought near the top will come back and  have to blame someone for their own mistakes. Anyway, hoping for a 2013 rally. Could be dead wrong though.
