Here's the usual script for canaries like QLGC: it pussy-foots around just before the top, then one last massive short squeezing burst to make a fake new high just as major indeces fail to make new high; then the cascading down. The fact that we are not seeing that massive burst, but only shorts building up (evidenced by the pussy-footing) is what hints to me that we are not at the top yet. All IMHO, of course.
You are just citing one of the many reasons I have donned a bear suit here. The whole Q except MERQ seems ready to dump big, if that happens, QLGC could reach $28.
