Sounds stupid matters but check blow off.

.

chart 4 day.  connect the june 06 high with the july 07 high and then extend and change back.  

.

Then try the same idea with EXS.v and you ill see the same chart.   I can give a lot of them.  It's the blow off. 

.

There are two more major aspects to this charting, i haven't explained. 

.

Why should charts matter?  I don't know,  I never have milliions of shares to sell or short.  When it does for some, its a make or break.  If it breaks, then it's a crush.  As has been written in many books, for a hundred years, insiders always know.  Insiders might not be officially working for the company, bur they are more inside than you.   They could be suppliers or financiers or product buyers.  But there is always people who know more s**t than you do. Charts tell you that.
