This isn't really true. An options value is derived from a variety of inputs that have nothing to do with the price of the stock, namely, forecasted volatility and interest rates. No real option market maker is using anything except th

I wouldn't call futures as very similar to options. The mathematical profiles of the two are very different, though a far ITM option is basically a future

Short selling is not illegal in Germany. I also suspect you are wrong about some of the other countries as well. But regardless, you would be hard pressed to find anyone in the industry who thinks shorting is bad. The overwhelming consensus

HFT firms do not front run retail orders. This does not happen.

I'm not sure about the breakdown for btc, but a very large amount of btc is owned by institutions. The flows have been staggering

Pretty much all institutional investors disagree with you on that. The institutional flows into btc right now are staggering

holding a hedged portfolio (with shorts) is less risky than a long only portfolio in the vast majority of cases. Moreover some asset that is risky on it's own can decrease the risk of the entire portfolio. From a quantitative perspecti

Um no not really. Fund managers don't all get together and decide what they should buy all together. It doesn't work like that.

I'm not sure that's true. Most of the medication I came across came from third rate Russian or Indian suppliers. I highly doubt the sales of drugs from these countries (also poor countries) to another poor country (Tanzania) was c

the bulk prices developed countries in Europe are paying is still much greater than some countries that have a truly free market system. For example, I lived in Tanzania and all drugs were imported and all of them over the counter. Drugs th

I used to live in Tanzania and over there, the trees are mostly shorter than the giraffes, but I'm sure they reach up to eat sometimes. I guess my point was that giraffes didn't evolve long necks to eat.

that's not how it works. Email me if you are genuinely interested in the how the institutional investors and market makers fit into this whole ecosystem. I'm tired of explaining market structure/incentives on HN. hint: wall s

giraffes have super long necks and yet they bend over to eat. The answer is runaway sexual selection (or at least that's the answer wrt to giraffes).

my workload is heavily compute constrained and I notice a big difference in the performance/time of my analyses on OpenBSD vs Linux. Most other people probably wouldn't notice it that much though. Edit: tbqh I haven't used op

I love OpenBSD but it's not very good for professional work, especially involving ml/scientific computing. No CUDA, and performance is pretty bad all around. It is superbly designed and probably the highest quality Unix around. It

Not sure where you work, but they definitely don't. It's all part of the game. Just make the sale, that's what matters.

Who says everyone here can't get a job paying 300k or whatever? Why is that statistically incorrect? Moreover, median != mean due to lefthand skew of the salary distribution of developers. Also probably excess kurtosis as well.

This is anecdotal evidence, but my mom was a teacher and she was getting paid 85k, had no masters, didn't work at all during the summer, and didn't work at home at all (<8 hour work day).

You can have a sample size of 5 and have it be statistically significant. Or maybe you are using some non-statistical measure of statistical significance?

Well a crypto currency can only fall 100%, so it's not unlimited. Moreover, some stocks do actually have a P/B ratio below one, for example Deutsche Banks PB is currently around 0.3. You could instead look at downside deviation in

Then you probably won't be pleased to hear that crypto derivatives are far more popular than actual hard crypto :) Most people are unaware, the the derivative volume of btc is yuuuge compared to the spot volume.
