What I didn't get at first is why all the cash and treasuries. Is it supposed to be some sort of "balanced" fund with all that gold, silver and francs, etc? Then I deciphered the name.
I guess the "permanent portfolio" approach has its adherents. And it has done well, beating the total market during the lows of the dot-com crash and since our current crisis, plus matching most of the run-up during 2003-2007 or so. But relying on prior performance is rarely a good idea.
To me, it seems a bit too heavily-oriented towards the "tin foil hat" brigade. Do I really want to own that much in precious metals? I don't think so. That much in the currency of one relatively-small foreign country? I don't think so. That much of my stock allocation in "aggressive growth stocks?" I don't think so.
I guess "concept stocks" are so passe. We've long-since moved on to "concept mutual funds."
I wouldn't do it, but it's your money.
