I don't know why anyone would want to teach a six- year old about commercial mortgage backed securities (CMBS), but this is how I would do it. This is INCREDIBLY simplified. For this example, our six year old will be named Lucy.
First, let's go to the grocery store. Have Lucy grab a basket. We're headed for the produce section. Let's grab a banana, an apple, an orange, and a tomato and put each in the basket. Good job Lucy! Quickly pay for the items and head home.
Now the fun begins.
