2008 was a shit show. We lost around 80% of all AUM in the space of a single month. Earned it all back in 2 years (40:1 leverage is a bitch when the market turns and what youre holding isnt liquid).
I now work at a firm that primarily operates mutual funds. Far less stress, but far lower performance of the funds. The MF is far more cobservative.
The great hedge funds look great, probably mostly due to survivorship bias. The ones that last are mostly lucky (although there's some strategy there).
Some of the big losers are also remembered. Such as Brian Hunter and Amaranth (fun read, look it up. Single trader blew up a 9 billion USD hedge fund). I also remember when someone taped a $2 bill to the front door of Bear Stearns when their stock price dropped below $2.
That said, I put in long hours over the years I was at the hedge fund. 80 hour weeks were expected. Did 6 months once of 100 weeks (only went home every other day). The only carrot to do that was the bonus, which for backoffice IT was was 20-25% of my base salary. I bought a pretty nice car with my last bonus. My bonus was certainly a far, far lower percent of my overall comp than the traders, but that bonus was huge for me. Also, my base salary was likely higher than the traders.
I should be clear that I was one of the best coders they had at that time. My work didn't suffer.
And maybe the most powerful weapons Wall Street has have nothing to do with them: investors get really amped up about an occasional big win (especially failing to understand when that win is predominantly explained by being near the top of an economic cycle or more generally correlated with some random variable well outside of anyone's control) and/or fail to track net results over time.
It reminds me a little of a blanket email that was sent out to the entire mathematics department while I was a grad student. The sender was looking to poach people who'd be interested in implementing his idea for the sports betting industry. He explained that he understood that any strategy was likely to have runs of poor performance, and his idea whenever it happened was to "swap" to a better performing strategy which was having a good run at the same time.
The actively managed hedge funds farther up the ladder get individual agents lower on the ladder to give them massive amounts of money they can take huge cuts from while putting little at risk themselves.
The people not managing their money as a job are at a disadvantage and the active managers can leverage that.
I'd suspect most people should passively track the market via index funds and then make the occasional active bet if they have some reason to.
The index fund bubble seems likely to be a real thing, but it's not obvious how to correct for it, so probably still worth doing total market and hoping for the best.
This is a well known bet from Warren Buffett, but you should not take conclusions without really understanding what the bet is about, and its underlying assumptions.
- The first assumption is that you're in for 10 years, this is the duration of the bet.
- The second assumption is that you don't need that money during the whole duration of the bet.
Why are these assumptions important? Because different investors have different risk profiles.
If you are in your twenties, saving for your retirement, then you should definitely follow Buffett's advice: just "buy the market" (S&P, Russel, whatever low expense ratio ETF or index fund tracking these will do).
This is because the longer horizon you have on an investment, the higher the volatility you can afford. It will always average out after a while.
Imagine now you have a different risk profile:
- You are now in your late fifties and expect to retire in ~5 years;
- You are an insurance company and may have to withdraw from your portfolio at any time to cover for expenses of your clients;
- You are an income investor and expect to live from the interests of your portfolio;
Would you be well advised to invest in an equity index? Definitely no! The volatility will crush you at the worst time, and you cannot afford to wait 5/6 years for the market to catchup.
In these scenarios (and there are plenty of them) what you want is diversification. You can accept to have less performance, in exchange for less volatility; so that once you sum all your different, uncorrelated portfolios, you have something with the risk profile that you can afford.
On a more local scale, you can apply this idea intra-portfolio. This is called "minimum variance" optimization.
Now there are a lot of things you can do to tailor your portfolio to your preferred risk profile. Traditional literature (e.g. "The Smart Investor") will advise you to buy some investment grade bonds, since they are almost anti-correlated to equities. You could also buy some real-estate, that will provide you cover during recession or very high inflation. etc, etc, etc.
What I want to emphasize here is that you cannot just look at the performance of a fund and decide whether it's a good or bad investment. If it exists, it means someone, somewhere, has a need for such investment, because it fits well with its current portfolio.

That's called "market timing", it's the unicorn of alpha combination. You will find multiple papers on internet explaining you why this is incredibly hard to do, and "beating the 1/n" is almost never possible.
I'm pretty conservative when it comes to gambling my own money so I doubt I'd ever go near a hedge fund. Since getting involved in a debate on here about the Kelly Criterion I've wondered on-and-off what the best way to bet is, if you want to maximise the bottom 5th percentile of your profit.
