The meaning of quantitative changes a bit with time and context. I would say the more "bayesian / sell side / derivative pricing" kind of meaning exists since the late 70s, the more "frequentist / buy side &#x2

Come on, don't create a trial of nitpicking. I am not saying returns are a law of nature meant to teach us normality. My point is that, for all intent and purposes, you should assume normal distribution of returns. If you don't, y

> explaining that stock prices are To be pedantic, stock returns, not prices. As for the quotes, I encourage you to strongly think about the meaning of the work of Sharpe, Black & Scholes and Markowitz applied to non normal distribut

Right, risk is often fat tailed, but unless we enter an expert discussion, for which HN is hardly a good medium, it is safe to assume 99% of strategies out there yield normally distributed returns. Non normally returned strategies are rarer

5x leverage is nothing, most retail brokers will offer you much better future initial margins.

> Is 10x borrowing even an option if we are talking retirement savings? Of course it is, though not exactly by "borrowing money" in a "mortgage" sense. Margin trading is a way to take leverage, derivatives is another.

I think when stating your opinion against 40 years of econometrical research, including multiple Nobel prizes in economy, you should feel enticed to explain your opinion a bit more than "no I don't think so"...

There's more dimensions to an investment than average returns. Volatility adjusted returns (or Sharpe ratio) for instance, will tell you how much returns you have per unit of risk you take. This is important because getting 10% average

Yes, though just to illustrate that it's a matter of taste, I do prefer the solution of virtualenvs requiring to source a script that append to PATH, rather than a solution requiring the use of a wrapper that executes in its PATH. I ne

Maybe I am biased, because I learned these things so long ago and I don't realize that it's a pain to learn. But what exactly is so confusing about virtualenvs ? They really not that different from any other packaging system like

Been using python for 15 years now, and these screams were never heard. Dev/test with relaxed pip installs, freeze deployment dependencies with pip freeze/pip-tools/poetry/whateveryoulike, and what's the problem?

by Galanwe 2y ago
Not sure this is still a valid critic of Python in 2024. Between pip, poetry and pyproject.toml, things are now quite good IMHO.

Spot on. Worst, these identifiers can even be point-in-time. I usually store them as you do, with an additional start/end date.

Usually the way it works is that when you hold a sensible position, you are flagged by your company. When you trade, your broker reports these trades to your company through KYC matching. This all gets summarized and sent to the local regul

It looks like you lack some understanding of how economy and finance work. I think instead of getting angry, you should spend a bit of time _genuinely_ trying to understand how the financial system works. I would recommend you (legally ofc)

Happy to see that, though it would have been nice if it retrieved the credentials automatically instead of explicitly requiring them.
