Is there anything similar to HN, that covers finance topics (such as markets, etc)?
Famous investors such as Michael Burry were discovered there. You don’t have to participate, you can have a guest account with a delay on seeing new posts. There are some insightful comments that you can read as well.
Edit: you don’t have to create an account to view posts
With that said, the problem we have is not one of curation which is what HN or Reddit does. The actual problem is the lack of strcture and searchability/discovery. Even on HN once something fades off of the front page, it is lost forever.
Here is an idea I have been considering for some time now: Imagine a website where you get to input a stock ticker symbol and you get back a timeline (literally a zoomable timeline) with all major events related to that ticker on that timeline. Each event has relevant links/documents attached to it. That way you categorize all the necessary information related to a company from its inception until today in one single place.
Even if you're talking about general finance and not stocks or investment grade assets. The problem is the same. We have an ocean of content all over the place but no structured way of search or discover what we seek to know more about. So imo finding creative ways to structure the content is the problem to solve for.
Some very intelligent passive investors there. You can learn a lot about the details of different asset classes, optimal ETF choices and intricacies of them like securities lending, bond interest rates and duration, portfolio construction, market factor investing, research paper discussion on historical returns, reducing taxes, etc.
You won't learn stock picking.
Places like bogleheads.com may be worth a look.
I used to be quite interested in finance or 'quant-finance'. Besides from taking too many courses in analysis and 'applied' mathematics like stochastic processes, bayesian methods, SDE's, etc. I have searched through a-lot of shitty Reddit forums and bad YouTube channels.
They are all bad, and no-one is actually doing anything. Sometimes there is Kaggle-competition like this one [1] where people are actually doing something and not just implementing a naive Black-Scholes model in Python with toy data, but again, in my experience it all linear models that run in production.
Depending on where you live I think there is a much higher change connecting with other people with engaging in finance-clubs at your local university or maybe get an internship/job.
The only real value I have got out from searching/reading about (quant) finance is [2] A Man for All Markets: From Las Vegas to Wall Street, How I Beat the Dealer and the Market, but you can skip the 5 first chapters.

Finance is essentially psychology with 6 months weather forecasting slapped on top of it.
It's way easier to predict the fate of the Universe trillions of years from now than it is to predict where Microsoft stock will sit 4 months from now.
