What this video covers
- How securitization transforms individual loans into pooled, tradeable asset-backed securities through a trust structure
- Why mortgage-backed securities use the 30/360 day-count convention for accrued interest and what triggers a clean-up call at the 10% pool balance threshold
- How collateralized mortgage obligation tranches divide timing risk rather than credit risk, and why expected average life replaces a fixed maturity date
- The payment priority and risk ordering of planned amortization class, targeted amortization class, and companion tranches, including which tranche absorbs the most prepayment volatility
- The inverse relationship between interest rates and prepayment behavior, and how contraction risk and extension risk affect investor returns
- Why interest-only strips move inversely to most bonds when rates rise, while principal-only strips behave like typical bonds when rates fall
- The structural difference between collateralized mortgage obligations, backed by mortgages and dividing timing risk, and collateralized debt obligations, backed by corporate debt and dividing credit risk
