Core Viewpoint - Investors often focus on high dividend yields without considering the long-term sustainability of those yields, leading to potential misvaluations in stocks like AGNC Investment Corp, ARMOUR Residential, and Orchid Island Capital [1][2] Company Analysis - AGNC Investment Corp trades at a significant premium to its tangible book value, attracting investors primarily due to its high yield, which is not a thorough research approach [2][18] - The earnings of AGNC appear strong due to existing hedges from low interest rates, but these hedges are expiring, leading to an increase in the cost of funds [3][8] - Even if the Federal Reserve cuts interest rates, AGNC's cost of funds is expected to rise because most of its funding costs are locked in through swaps [4][5] - AGNC's hedge portfolio includes a substantial amount of interest rate swaps, with $47.8 billion in long positions, which are crucial for managing interest expenses [7][8] - The yield on AGNC's assets is increasing, but the cost of funds is rising faster, resulting in a declining net interest spread and lower coverage ratio for dividends compared to two years ago [11][14] Comparative Analysis - ARMOUR Residential and Orchid Island Capital are seen as less favorable compared to AGNC, with similar risks but poorer decision-making and performance [14][19] - Preferred shares and baby bonds in the sector are viewed as more stable investment options, offering yields of 9% to 10% without the volatility associated with common shares [16][17] Market Sentiment - AGNC's current price reflects a large premium over its tangible book value, which is unusual and may indicate potential future declines in share price and dividends [18] - ARMOUR Residential and Orchid Island Capital are trading close to their book values, which is considered expensive given their historical performance and frequent losses [19]
