Ameritrade Online Investor Index

Occasionally I take a look at what the "little-guy" is trading these days by pulling up Ameritrade's Online Investor Index. The website shows the top 10 daily buys and sells of their clients.

There are a few things you can glean from today's report. First, investors are trading a lot of big cap stocks (and there are a ton of buy-the-dippers in General Electric (GE)). Secondly, what's the deal with significant interest in Dynamic Materials (BOOM)? I know the stock has been a winner, and it is apparently a very popular trading vehicle. And, finally, it is interesting to me that traders still are attracted to shares of Calpine (CPN) - obviously, they see something there I don't.
