The skill is in identifying the things that will make money in the future, and then actually doing those things. Sticking with it over long periods of time is the real skill. Even aaron brown says it's not obvious. It's kind of hard to tell. Like he met bill gross a long time ago. He was near bill gross's headquarters in newport beach. And maybe you've been thinking, because the markets are absolutely falling apart, it'd be great to identify a good manager beforehand. That's obviously the classic problem in finance. Past performance is no guarantee of future results.
