They touch on
-Why US stocks looked so unattractive just before their largest bull run
-The danger of stock/bond correlation
-The Sharpe ratio of your fire insurance
"In 1983 when I had some money from my computer software business, I look back at Track Records and the stock market was completely unchanged in real terms for a dozen years.
And I just like why would anybody invest in the stock market? I want to be in the bond market."
"My whole career, until recently, has been spent in a falling rate environment. And it's only now that we're starting to see the potential for bonds and stocks and moving the same direction.
And that throws off this whole 60/40 idea that you should have stocks and bonds and...
of course risk parity.
when you have leveraged multiple times to things that are positively correlated that's a tremendously risky trade, especially if that trade needs to be reduced when volatility increases
A lot of people are very comfortable with protective strategies in other parts of their lives such as fire insurance, let's say. So if you ask me, what's the Sharpe ratio of your fire insurance?
You know, you know, scratching like, oh, it looks like it's minus infinity...
That's literally the worst investment you'll ever make in your life. For 96% of people or something like that, it will never pay out.
But everybody has it."

1/ One lesson I learned from sports is that the best way to be good at a thing is to do a lot of that specific thing.
This seems very obvious but often people don't do it.
2/ In the case of sports, lifting weights and being in good shape can help you be good at basketball, but the person who is less in shape but plays a lot of basketball will be better.
3/ I went to high school with a few people that went on to play D1 sports (one went pro) and none of them really spent a lot of time in the weight room, but they practiced their sport a ton.
I had a friend in college that I used to get in big debates with about all sorts of topics, mostly religion, economics, and evolution.
He was religious, had studied Austrian economics, and doubtful of natual selection.
I was on the opposite side of nearly all those issues.
We had very different view points but it was really rewarding to talk with him because, though I disagreed with him, his opinions were well thought out.
If anything, it was frustrating because I wanted to “prove” I was right and never could.
We are still friends and it’s been interesting that over time, our views have somewhat converged or at least grown more nuanced and moderate.
I appreciate the role of religion more and have a deeper appreciation for the Austrian school.
1/ Perhaps the most important factor in deciding whether to build custom software or use a 3rd party provider is the cost of the "tech debt" on your company's balance sheet.
2/ Most people don't think about it this way, but when you build custom software, you are effectively buying a rapidly depreciating asset that's going to have to constantly be repaired.
3/ At the margin, it's almost always better to use a 3rd party software that's not quite as customized as you like b/c what you lose in personalization is more than compensated for by moving the tech debt onto someone else's balance sheet.
one of the best lines to ever appear in print IMHO
Also, the Margin Call speech is perfect
"There are 3 ways to make a living in this business: be first; be smarter; or cheat. Now, I don't cheat. And although I like to think we have some pretty smart people in this building, it sure is a hell of a lot easier to just be first"
