Great explanation.
I'd also add that the P's had a much higher dividend than the K's (when it was being paid). Back when we thought JPM would take over the preferred, the P's would do you a lot better dividend-wise.
But people are bewildered by why the ratio of P to K is so far out of whack.
I think they're not seeing the obvious reason. It's because you can't buy as much (dollar-wise) K as you can P. The total face value of all K's is $500,000. The total face value of all P's is $3B.
I mean, look at how much money changed hands in P's and K's on Friday:
P's $374,605 (18,499 shares @ 20.25)
K's $27,419 (30,131 shares @ 0.91)
$27,419 in K's ? That's chicken feed.
If moneyed investors (including the MM's who are accumulating) want preferred, they almost have to buy P's. There aren't enough K's to buy! Or said another way, since K's are scarcer (dollar-wise), you pay a premium to get them.
But in my opinion, it's "silly" to pay the premium (for K's) and get less of a return on your money. I'm quite confident that the P's and K's will be treated exactly the same!
