They did the same thing with PHK last Fall. It was sitting at 14+ and then they claimed it was way overvalued in comparison to book. The thing dropped down to about 11.50. It's recovered some but has never made it back up to 14. Barrons ought to be sued.
On the PIMCO thing they didn't even have the %^%#@ to publish the article during the week. They slipped it in on a Saturday. At least the article on AGNC was out there during the time the market would be trading. But Barrons IMO is still a bunch of jerks. They always seem to go after high dividend paying stocks and then try to tear them down.
