Rada?

[Experienced Investors llc]

Did anyone hear about a stock Rada?
I own a small amount of it myself and every time there are good announcements/news published about new contracts or reports, it shoots up. About a month ago they got a new order and the stock went up by a little bit (it was a $3.2m so no one expected it to go up by much) and stopped, like it normally does. 2 Weeks later it started going up by a lot for no apparent reason (it completed a 50% climb in the past 10 days!). Also, the volume was significantly higher than average, it actually made the 3 month average double.
I wanna know why? What do all those people, who bought so many shares for so much, know that I don't know? I looked in every source I know, asked all the other investors I know, and nobody heard any news. If anybody knows anything or has been following this stock, please reply. I'm a little suspicious about what's going on with it, it smells kinda fishy. The last 2 weeks are completely unexplainable.

It could because of institutional traders. They always know something before the public and they often can control market movements if they buy a lot of shares.
