This is a good write-up but it's also missing huge other sections of quant finance like statistical arbitrate and factor investing. I guess you could put this under the 'market taking' section except everything he describes

I don't disagree exactly, but you don't think "maximum pain" has a deterrent effect? I don't want to experience maximum pain myself...

I think you completely missed what I said...you are again pointing at numbers that compare averages and I am saying that the averages are irrelevant. If half the people do great and half do terrible, the avergage will look merely ok but th

I think what people in Europe don't appreciate about American healthcare is that the quality of care is a bi-modal (or maybe even more than 2 modes) distribution where a very large fraction of the population does in fact have the best

If it's strictly a linear program, it's probably fine. You can always find the global optimum. Seems more likely to me that it's non-linear, which then depends on how non-linear (quadratic only?), if it's just the objec

If you do your time, you are square with the state. That doesn't and shouldn't mean private business or individuals should be forced to accept you. Should we make a law that says your friends and family have to accept you once y

It's not really a "loophole", per se. It would be ludicrous to say that a bank should not be able to exclude someone from hiring if they have been convicted of a serious financial crime, or that a day care should not be able

They are probably market neutral. For as many dollars they are long, they are short an equal amount. Therefore it doesn't matter what the market is doing. It matters that their longs outperform their shorts.

What the market is doing isn't really relevant to a market neutral strategy, and that is almost surely what they are running. The goal is to make money consistently, whether market is up or down.

The problem is that you think they went out and investigated this topic then wrote about the results of their investigation. In reality, they had a narrative and agenda they wanted to pitch and then went out to find confirmatory evidence, w

Just buy shares of SPY. It tracks the S&P 500. Keep in mind, returns aren't everything. They have to be considered along with risk. The S&P 500 also has big downturns of 20% or more. A good measure of return to risk is the s

In the US most allow but not always. For instance, NYC recently passed a law forbidding it. Many companies will not report anything other than whether or not you were an employee and the dates of your employment, but that is by their choic

On the other hand, if you can make an organization work with a lower grade of employees, you will scale much more easily and cheaply. Maybe its a pipe dream to accomplish this but I think it's probably somewhere in between. At the sc

Yes, it is. This is a forum run by a startup incubator. People are encouraged to promote their work, within reason.

I am seeing this as well. Getting 503's for almost every product page I click. I have met a lot of the dog's of Amazon, however.

Those are hypothetical causes but they don't actually line up with all the observations. For instances, poor people are fatter than rich people. Shouldn't rich people be fatter since they 1) don't have to work as much manual

Well, I don't think that is going to "solve" the underlying problem. It might help the government pay for things, but it's not going to solve the obesity epidemic. There are already huge intrinsic and extrinsic negative

They're great for shy teens buying condoms or husbands buying tampons for their wives. Other than that, it's worse service for the same price.

For sure no, but in fairness, you might need to before you remember just how hard it can be to actually do those things.

I hear what your saying but can't you use the same logic with bathrooms? Sure, we could all get by with 1 bathroom. Hell, we can get by with just communal bathrooms. But it turns out it's nice to have the luxury of not sharing t

The problem is people outside the field of whichever cert pile into them as a means to break in, so the median cert holder winds up being inexperienced and overall unqualified. The cert itself then becomes associated with that. You'r

You're right that the existence and quantity of news does not necessarily indicate bias, however, bias is found not just in news that is reported but also in what news is reported versus what news is not reported. I personally find th

I agree with that in general but having your monitoring system be dependent on the thing it monitors is a pretty big goof. It possible that the dependency was very non-obvious and many layers deep, which is more understandable, but still..

Longer than that. This article was passed around at my job to laugh at.

The thing is that this is really only true for people in dense urban environments. For instance, parking is not an issue in suburbia. There are use cases, like getting from your home to the train station, but it's not nearly as univer

Not disagreeing with your points about L1 but I want to point out that you can also do things to make L2 more robust to outliers (and have better empirical performace), such as winsorizing the data.

In the same vein, it's also a wonderful validation of secret ballot elections, and why things like "card check" should never fly.

I believe this behavior has been dubbed "Resume Driven Development". I am sure I was guilty of it when I was a junior developer. It extends from over-engineering to also selecting the hot new technologies rather than the tried and
