I'm also here to echo the trader != portfolio manager which seems to be described in this article. There's a vast difference in duties and comp between the same job title at a bank, hedge fund, or prop shop and you really cannot look at only comp and job title for comparison. I suspect some data points from hedge funds and prop shops got mixed together. A typical trader at a hedge fund is not making anywhere near the comp claimed in this post and "senior trader" at most places is like giving you a gold star because they didn't want to promote you to portfolio manager.

Additionally, 2 and 20 literally does not exist anymore for the vast majority of funds. Downward pressure on fees has been all over the news for the past several years and having the inaccurate data point as well as no mention of recent trends leads me to doubt other data points in this article.

The revenue split also makes no sense and does not account for fund size or strategy which has a huge influence on costs.
