Negative Nancy's?  While one must put the brand to the calf when the iron is hot, let's be real.  Typically, a stock will rise for only about 3 days before sellers take over.  There are exceptions, of course.  The point is, rapidly rising prices attract volatility. 

In this case, news has to come soon to sustain the move.  Having said that, it's the trend that can be your friend (or your enemy if you don't understand how to take advantage of it).  A little luck helps too.
