AGNC Investment (AGNC) joined the S&P MidCap 400 Index on Sept. 21, increasing institutional ownership as index funds must buy shares.

AGNC Investment: Fed Policy Shift Set To Cause More Pain (NASDAQ:AGNC)

AGNC Investment (AGNC) was downgraded from 'Strong Buy' to 'Hold' due to rising interest rates and profitability challenges. The Fed's rate hike increases funding costs, narrowing AGNC's net interest spread and potentially reducing its book value.
