Ask HN: Is there any serious discussion about the stock market online?

To me it often seems, HN is the only intelligent site on the net. At least for posts that get a lot of votes. Then usually some substantial comments get voted to the top and the nonsense tends to sink to the bottom.

I think a lot about the stock market and would love to read some discussion about company valuations. But I have found nothing so far. Neither on social media, nor on classic newspaper sites. All I found so far is cheap nonsense.

Is there anything out there worth reading?
