I guess because the article is talking about insider trading through the use of options and your point on Taleb is how he traded options like any option trader would. I should be clear that what you seem to think ties these together, i.e: &

Doesn't that mean he was long volatility? Taleb's point seems more to be that he saw a mispricing and traded on it one day, rather than anything profound regarding option pricing, unless I am missing something. Anyway, it has litt

I agree with you that it's possibly unanswerable, which is more or less the point. The broader idea is that there are lots of obscure interactions like that one I made up. You can switch up the doctor and CEO patient for anything else.

A relevant aside: surely insider trading is happening all the time? There are so many daily market-shifting events involving so many privy parties that it seems inevitable to happen every few minutes (not defending the actions in the articl

Even as a math graduate, I still think calculus is a bit weird. The idea of successive approximations for a slope culminating in a dy/dx term -- where we say dx (really the denominator of the limit definition) is obviously not zero, bu

Isn't this also related to how the vaccines-cause-autism conversation started? The study involved only had a handful of subjects (a few of which were very unqualified), and then a big important journal (The Lancet IIRC) picked it up fo

Eh, I think one could say HSAs are also a symptom of these disproportionate effects. What populations are getting the jobs that provide an HSA? What population has money left over to put into an HSA? etc., etc.

Not sure I followed what you meant by >= $26 in 2a. The max profit one can make is $26, by drawing 26 red cards in a row, never more. You are correct though that you'd never want to stop on a negative number, as you always can execu

It's unclear to me how much of it is an intentional misrepresentation vs. a convenience that ends up being misinterpreted. Those are good examples! I never thought about the widespread use of the marginal value as a proxy for general v
