It also has bonds in its portfolio. I wish I had bought some in 2001 (!), but I only found out about it in the last half of last year. I read one of Harry Browne's books in the early 1980s and wish I had opened a Swiss bank account like he advised. Anyway, I got some of this fund in January, and it's up over 6% -- seems pretty good to me.
Another message talks about its weird correlation to the market. Its R-squared is very low, which means it's not very market-driven. (Of course really it's driven by at least four different markets -- stocks, bonds, precious metals, and fixed interest, plus cash.)
In its portfolio it says one investment goal is protection of purchasing power, which it has done very well since 2001.
