That's why I hate playing anything but the ETF's that are tied directly to the S&P500 charts... When you play SSO going Long, and SDS going Short on the market, you don't have to worry about what might be affecting the oil stocks, or any other sector for that matter...
Don't get me wrong...TSO has been my favorite stock to day trade for a few months now...And it will probably remain so as long as it shows the volatility I need to see in a good day trading candidate...
