While it is always unsettling to watch the price get hammered like this, it is a common tactic used to scare away some of the more skittish retail investors to allow institutions to pickup more shares.
Look Harry, I liked it at eight, I love it at four. It's an average down for you. Dollar cost averaging. If you own a hundred shares at ten dollars and now you buy another one hundred at five, that's a F200 shares at $7.50 a share. Your cost basis is lower. Now if I get you involved at ten and take you out at fifteen, you've made how many points Harry?
We all know these stocks can be risky... just average down man...
