Senior preferred shares need to be cancelled for there to be anything left for preferred shareholders. That is basically the only thing needed for preferred shares to jump 300%+.
That is why it's a safer bet than common.
In wind down and liquidation, preferred just need that one thing to happen. Common get wiped out.
In recapitalization, that one thing happens, preferred win and common need to withstand significant dilution.
This is still a "rising tide raises all boats" scenario for GSEs (we all win with a court decision or shareholder friendly deal), but there is actual value in the preferred shares which makes it more of an investment than a gamble.
