Not sure what you are talking about. Give a link to any selling by dickran. All I see is buying. Maybe reread what I posted:
Then you even implied that dickran had sold close to 100 million shares when the filings you linked to show that is not the case. Just look at the dates and you will see the 3/11/2019 filing disclosed ownership of 306 million shares and the one that followed on 3/20/2020 detailed the purchases of another 99 million shares bringing dickran's total to 399,303,010. No where is there anything showing he has been able to unload.
