That wasn't the question you asked me. You asked about the bid yesterday...that was most likely entirely retail.
But I get you don't really want to talk about yesterday now.
As for the "last year and half" are you serious? Nobody knows what percentage of that was flipping, how many times and given share traded hands. And the simple fact is that there has been but one 13A/D/G form filed and that was by BRU LLC...and they weren't buying there stock from the market, they were issued by the company.
So there is no evidence that there is any major player or significant accumulation by any individual....other than some retail shareholder(s) that say they have accumulated "close to a billion" shares.
