I guess that it is only one Nisse Sandberg. Fund itself is probably not so great. They manage money for a table tennis club, this is their most famous player. He is more famous than Michael Jordan in China. http://en.wikipedia.org/wiki/Jan-Ove_Waldner
If you have questions about JF you should mail nisse.jordanfonden@bredband.net
By the way, it is estimated that the JF members and other Swedes own >30% of SIAF shares. I am also convinced that a huge amount of additional shares have "crossed the atlantic" the last couple of weeks due to the share price drop. It would be interesting to see the share volume flow to Sweden. Anybody knows how to get this sort of info?
