ARMOUR Residential REIT Inc. (ARR) fair value

ACCE thesis

ARMOUR Residential REIT owns and manages a levered portfolio of agency residential mortgage-backed securities, the government-guaranteed mortgage pools that trade in the to-be-announced market, financed largely through repo borrowing. Its edge is less a franchise moat than a specialist's balance sheet: the company's returns depend on managing prepayment risk and funding costs, and that is where its track record has to be judged. The reported 126.1% revenue growth and 87.0% operating margin reflect interest income and mark-to-market swings on a leveraged book rather than operating businesses, so they should be read with care. The stock screens at 3.4 times trailing and 5.1 times forward earnings with a 20.3% ROE, a combination that signals the market doubts the durability of that earnings stream. It deserves a deeper look only if you can form a view on the spread between mortgage yields and repo funding costs and on whether the dividend is covered by distributable earnings through the rate cycle.
