I am new to trading, but I like to learn about trading on a sector. In the last couple days, I started trading home builders. I observed the charts and they seemed to move in the same direction in almost the same time. They broke intraday newhighs together. I think there are several ways of trading a strong sector. When the group is strong ( by looking at the sector index or the prints of the stocks ), 1. Buy the whole group together 2. Buy the leaders 3. Buy the laggards I tried (3) buy the laggards. When the leaders broke new high, and the laggards was still not in the new high but the trend was up, I brought the laggards. When the leaders struggled and seemed to top, I shorted the laggards. What do you think? What methods do you use for sector trading?
