Keep in mind that there are only about 6.5 million shares outstanding and that 75% of those are held by institutional holders or insiders. That means less than 2 million shares for average shareholders to trade. Hard to get much volume like that, but if they get things rolling, that will be OK.
Looking at the long list of institutions that own HURC on the the yahoo finance site (click on "major holders under the ownership heading) I see that there is a column that says %out. What does that mean?
