There was no halt to AGNC trading. It was some sort of glitch at Interactive Brokers I've come to find out after speaking to the trading desk there. I only posted to see if anyone knew anything because I could find no news about it. I apologize for the confusion. I hold many January AGNC calls and some common. Good luck to all holding AGNC.
I totally agree it's odd. I got the announcement from Interactive Brokers but couldn't find any news and was hoping someone else might know what's going on. Also the 15 minute after-hours chart on TradeStation shows a green bar up to 33.
