Pinetree and Sprott are buying because the sector as a whole is poised to see significant growth.  That's reason number 1.  They didn't buy just to drive some junior companies' stock prices up.  That fortunately was the result of their participation....and only the beginning.  Just think of what is going to happen when the real reason they invested into the moly sector starts unfolding.  Of course they bought into the companies that they believe have what it takes to succeed for the long haul.  If our share price has performed this well just on the involvement of these two institutions then we haven't seen anything yet.  Watch what happens when the big market money starts flowing into the moly sector and the price of moly is rising.  They won't be selling anytime before the big picture unfolds.  JMO
