My observation is based on the market prices of the individual preferred securities.
The prices would be trading at much higher levels and they would be closer among the various series. Right now it is too wide. Market is still pricing higher yields at higher prices.
I am willing to review this if you can provide a chart with the public announcements of said conversion and terms at least 30 days before and after of event.
I never said it did. Market is often mispriced from expectations.
