CDOs, Tranches, and Risk: A Guide to Slicing and Dicing Debt (Without Losing a Finger)

Collateralised Debt Obligations (CDOs) sound complicated because, well, they are. But at their core, they’re just a fancy way of repackaging debt - mortgages, loans, bonds - into bite-sized chunks that investors can buy. Imagine them like a massive financial cake, where each slice (or tranche, if you want to sound clever) has a different level of sweetness (returns) and risk (potential indigestion).

But here’s where it gets interesting: not all slices are equal.
