The company doesn't control or manipulate the price. I don't see how they could. If they make a peep they risk people believing a SPO is imminent and then the price would tank. They probably don't even discuss it internally until the guy with the spreadsheet that considers all of the variables from the cash level in the company treasury to the Agencies' inventory levels to the hourly spread quote to the Fed's MBS demand to the prepayment rate to the duration and convexity available in various buying schemes to the color of Malon Wilkus' tie and says "we're in the butter zone". And then they start negotiating with the underwriters who have their own models. And when the need for cash and the price they're asking and the price the underwriters are offering bump fists in the circled square, we're ready to rumble.
I know they just did one about three weeks ago. But why should that stop them? They had to pay the div on the previous SPO and they didn't care. There is NO REASON for AGNC to be rising like this unless they want to do a SPO.....maybe even after hours today.
There's no reason to own an Mreit right after ex-div.......especially one that won't go ex for another three months. Nope....they are pumping it for a SPO. I've seen it happen many times. This is no different.
