Thanks for your advice, that makes perfect sense. I'm sticking to index funds!
Prob the wise choise in the long run. Very few active managers outperform the index in the long run. This does not mean that such managers don't exsit, but its pretty much impossible to know up-front which one actually will. Also, there are so many trying that some will outperform fairly consitantly over several years even by sheer luck. A lot of highly paid smart folks spend 60+ hours a week trying to achieve this, most don't, at least not after fees which can be substantial.
The fund you linked to appears to try and achieve a few things: They do stock picking - probably still staying well diversified, they also actively manage their FX exposure so they also try to outperform a passive FX hedging strategy so they need to, over time, outperform on both fronts.
That said, the recent case for passive indexing might be a bit rosier than reality - the last 10+ years the winning strategy has pretty much been to buy everything and close your eyes, the performance of long-short equity funds has been pretty bad relative to index as almost everything has ripped. If - and that's a bif if - we transiition to say a decade of stocks not really going anywhere the outcome might be quite different. But regardless you can't know in advance.
