"Only"? When it comes to that series, or any other series that isn't FNMAS/FMCKJ (and maybe FNMAT), 30k is significant volume.
I think you got a pretty good deal if you were able to get all 30k shares at $3.25.
We should find out in January how much of the recent selloff was for tax loss purposes.
I don't think it was a large percentage, though. Any junior pref holder that sold after the post-Collins bloodbath in 2021 already had significant tax losses which would have been pretty hard to offset in 2022.
