This one chains together pricing, yield curves, and credit spreads to tell you if a bond is rich or cheap. You price the bond, pull the risk-free curve to compute G-spread, subtract the credit curve component, and whatever's left is the residual that signals mis-pricing. Then you stress test with rate shocks to see if your view holds. The workflow is methodical: it walks you through spread decomposition tables and scenario P&L grids rather than just spitting out a number. Useful when you need to justify a trade beyond "the spread looks wide" and want to quantify how much of that spread is actually credit risk versus liquidity or technicals. The historical pricing hook lets you see if current levels are extreme.
