Based on a quick visual scan of estimated daily volume for 3Q its fair to say NHF scooped up nearly every share the grey market had to offer.
Based on that assumption I see no reason why their [NHF] buying would stop. The pps hasn't changed and more shares have become available on average in 4Q. I should go back and do the actual figures on daily volume to see how 4Q is tallying out but its a lazy Saturday morning and its hard to maneuver a pencil & paper while working on a cup o' coffee & toast.
4Q definitely has on average racked up higher daily volume(s). So its safe to assume NHF could have added about 30% more than their total for 3Q.. resulting in a 4Q total of 371,000 shares.. give or take 10k.
Its hard to read the melted butter math on my toast but I'm going with 371k as my guestimate for 4Q. ":-¡
