I also like ROVI and PWER. Since PWER reports this week then I will not trade it. However, ROVI which does that report until August, I will try to enter as it does not report earning till August like DTG.
After the gap down this morning, I was expecting that markets to rally and likely close positive. However, I did not expect to see what I am seeing now and that is why I have broken my rule and initiated positions intraday (that I did not plan for the night before). None the less, my risk on my trades are well defined and so barring some thing out of the ordinary I will likely live to see another trading if the trades do not pan out as I foresee.
Good luck and good trading!
