The proof is in the pudding Now only 30,000 shares short of the 50-day avg volume with 140,000 traded by 11:28.
Looks like a bit of institutional buying going on.
The 50-day avg volume is 172,000.
If it breaks that soon, and if volume remains steady, it's very likely news is imminent.
And if volume actually accelerates, rather than dying off as has been the habit of late, you can be sure of it.
500 k or more would attract attention, however unlikely that seems right now.
