Fannie Mae-No Politics (FNMA)

[Always wondering]

Is this possible? Low volume because shorts are scared to take further short positions because every time they try to actively short the shares get eaten up by money managers and retail buyers and whoever else, putting shorts in a deeper and deeper defensive hole while pps moves maybe .10 down for moment, stays where it is or even rises a little?

TIA, just looking for a reasonable explanation to the anemic volume.
