Not giving official financial advice here because I would need to understand your individual circumstances, but if you have the view that equities on the whole are going to fall, you can buy bonds, uncorrelated assets (think gold, but calcu

That’s what I’ve always said. If you smeared a bit of poop on your face or arm, you wouldn’t be content with just wiping it down with a thin piece of toilet paper. You’d probably shower! So why should your ass be any different?

Very much agree with this. In some ways it appears intentional. To avoid “giving away the answer” professors will sometimes hand you a very fuzzy set of loose rules, perhaps 2 example test cases and you’re off to the races. It’s funny becau

Arguably, reciprocity and a strong independent nationalistic streak are the principles the US were founded on. For example, dumping tea into the Boston harbor to protest taxes imposed by a “””foreign””” government

I've pulled off some pretty great trades in my time, for example, I had the conviction that the Sprint merger was going to get approved and I bought Sprint stock in January, nearly doubled my money. The only problem is that I've o

I’ve used F# and USING it feels very similar to OCaml in all of the important ways. The lightweight type structure where you can easily make Union types and the pattern matching are pretty much identical to how OCaml does it. Of course, the

I’ve never fully understood why bots are seen as subverting democracy when things like flyers, posters, and yard signs aren’t. If I go to an empty lot and I put up 50 Mike yard signs, what’s the difference between that and a bot that makes

Here's a pretty good tutorial [1] (albeit a bit old) on how to price credit default swaps using a typical Bloomberg function. This kind of esoteric fixed income calculator is what makes Bloomberg so dominant. Otherwise, you'd have

If you give a quote as a trader you typically give the other participant some time to answer you. If the price moves against you since you last quoted, you typically say something like "off" and ring the bell so that the other guy

The way I was taught is that Marketing is really about communicating the value that your product creates for the customer, and then capturing the company’s portion of that value created. Some textbooks call this Dual Value Creation. Sales i

The sell-side investment bank alone is a huge consumer of this tech budget. 13 exchanges x 3000+ securities x 2 quotes for each security x 23,400 seconds in the trading day (with the very very very generous assumption that quotes only chang

It’s not just tellers getting replaced though, it’s brokers/salespeople/traders - jobs that were once coveted. I foresee a future where every major bank just gives their clients (hedge funds, asset managers) an API that they can c

I think that one advantage of sending humans is that we can gather data about how living in space affects human beings. We know what zero-g is like from the ISS, but what about the moon with 1/3rd g? Etc How do we deal with the radiati

Hypothetically, the Core PCE would be a better metric of inflation, but Core Urban Consumer NSA CPI works pretty well. It has some flaws, like failing to take into account new products or improvements in products, as well as being susceptib

Not only is 2% a fairly tepid number, we’ve had to cut rates, make promises to “sustain the expansion”, stop the tapering of The Fed’s balance sheet just to get that 2%. All throughout 2013-2017, the CPI number has hovered either close to 2

You would have to tariff every country with a comparative advantage in manufacturing cheap goods, not just “the cheapest countries” in general. Otherwise, we’d be moving our production to Pakistan and not India (a country with a comparably

I think the trade balance is too skewed in favor of the US. It will be painful for both sides, but we have a lot more goods we can tariff than they can. Of course, they could also dump their US treasuries, but it would be a pyrrhic victory

To enhance point #1, you don't even need to have churn rates that change over time. Consider a very simple model where the probability of "disengaging" in a given year is 50%, at which point the follower doesn't engage a

You can’t write software in a vacuum. To write good code, you need to understand the whole program (or at least a very substantial part of it), why certain decisions were made in the past, the potential ripple effects of a “simple” change,

I’ve never really bought into the argument that if we set aside our phones, all that liberated free time will go towards “something useful.” People aren’t going to spend those 2.5 hours a day learning a new language, or coding a side projec
