I'm by no means familiar with the fund, but the fact that the overall portfolio has been around since 1998 doesn't mean this particular strategy (the Density fund) has the same experience.
Ok, the strategy existed since 2001 but it is not clear to me if it was actually traded and in what shape / form.
I'm in no way saying anything negative about the fund, but it makes sense to look a bit deeper into the details before drawing conclusions / asking 'rhetoric' questions...
I was under the impression the Density fund had been around since 1998 as per the article. Using 'portfolio' in this context is misleading, Reuters should just use the term 'fund' or 'across all funds'. The fund's website is confusing as well, there doesn't seem to be an english version.
