The maths are exactly the same. These sorts of math problems are the focus of this week’s TBL. Math Problems As this TBL goes live, just 16 games and one day of the NCAA Tournament are in the books, yet my bracket is a mess. We notice the unlikelihood of 100 in a row because of the pattern.

Part of the math that determines options premiums is the risk free rate of return from T-bills. The way circuit breakers work has made a 1987 one day 20% crash almost impossible (it would play out differently) but a repeat of the Flash Crash of 2011 or 2016 would probably smack the hell out of QQQY.

But in the Mustachian Era (the years since 2011 when I started writing this blog ), there has only been one: the 2020 Covid Crash which only lasted about a month.

This is the best thing I read this week (it combines magic, music, mystery, and math); this is the best thing I saw. Even better, I should have paid a bit more than $14 and bought zero-coupon UST STRIPs that would have paid par ($100) 30-years later in 2011.

So like a component of it was like the standard derivatives math, right? And so like, you know, I got there and I learned derivatives math, right? It was derivatives math, it was like working with the traders on like risk management. Like, like the, you know, like the accounting standards.

We had kept an old 2011 Honda for us to use when we’re east. We checked the maps, did the math, and determined that, if all went well, we could drive from BWI to San Diego in about 40 hours of driving time. More than that, however, we had purchased tickets for Disneyland for everyone for Wednesday. We wanted to go!
