there is an argument to be made that investors with long investment horizons and predictable flows aka insurance companies and retirement funds are exactly the ones who should be taking risky long term bets instead of looking to next quarter
The main reason we are seeing private equity now being offered in 401ks isn't that it's going to be great returns for your average mostly-self-directed worker, but because those managing private equity believe they will make more money if they managed more capital. There's no guarantee that they are making any choices there that provide good risk-adjusted returns. But the managers sure would be making more on fees.
The defining thing about "high risk" is that risk part will happen and that creates a lot of loosers. That is the whole point!
But HN treats "high risk" as something that is expected to always give you reward.
