I just want to make the observation that this whole SpaceX IPO is turning out entirely unlike the CDOs that led to the 2008 financial crisis. There's no mixing of AAA level assets with a bunch of subprime stuff and then getting someone to buy it all as AAA. Not at all similar. Completely different. Will turn out just fine this time. |

You should learn about securitizations. It’s actually interesting. But people talk about it colloquially and so incorrectly that it’s mind dumbing.
Here’s a simplified example of how you can take something and turn it into a safe investment:
Suppose you have 10 loans and each has a 50% chance of default. Ignore coupon, and say they are $10 each. Expected value is $50
If you were to put this in a deal and cut it up into tranches, say the first tranche gets the first $10, this would be your AAA bond because odds of getting paid out you $10 would be > 99.9%. The equity (bottom tranches) would pay a lot less. For instance the expected value of the bottom half would be considerably less than $50 that is being promised. So there’s upside since you’ll be paying cents on the dollar and even though in the median scenario you’re making nothing, you have to weight the expected values of each scenario to figure out how to price it.
The problem w this model is that it only works if assets are relatively uncorrelated which wasn’t true (it was true in the past but ignored systematic risk and adverse selection in originations).
What this has to do w musk or spacex I’m still not sure
