One thing you can expect from thinly traded stocks is sloppy bases. EXAC is one from the earnings database. There is no news on this so I don't know the reason for this move. I would have missed it had I not had clearstation alert me to it. If you want to track these stocks, I strongly suggest getting a clearstation account (free) and entering them in to the watchlist. Clearstation sometimes has technical problems, and the accuracy of the data is sometimes questionable, but I find it highly usefull. I have used Telechart in the past, but since I am committed to using free resources for this blog, I no longer use it, but it is ideal for an application like this.
