After pondering a bit more, seems obvious this is not the company buyback for multiple reasons: in blackout period, too much volume as it would have exceeded the %limits for daily buys, and no way would the company have burned 30% of the buyback in one afternoon.
I also have a hard time believing anyone wants "in" before Monday's earnings release. Just about no matter how good it is going to be it will be worse than the year ago Q1. Last year's Q1 was roughly $6mil revenue and $2.4mil in net income.
It also irritates me that so many were willing to part with shares today at sub-2.50 prices.
So I obviously still have no clue. Probably just a person or money manager or small fund starting to buy some shares for the long haul. It will be interesting to see if any follow-through tomorrow.
