I'm afraid I have to agree. It's stupid.
The first two planks aren't bad; mixing your investment about equally between debt and equities is basic investment 101 advice. I tend to go more heavily into equities, but that's because I'm still fairly young and consider poverty to suck; if you're close to retirement and more worried about capital preservation, go with more debt. I also think that treasury debt is probably a worse choice than private debt unless you are playing silly tax games -- which, if you're taking investment advice from a web forum, you shouldn't be.
Keeping a fixed percentage of your money in cash or cash equivalent is stupid. Keep
as much cash as you need; no more, no less. Cash is a lousy investment, and you get just as much safety from the treasury bills and better return.
And 25% in gold? That goes beyond stupid to "conspiracy-tard." I don't know where this idea that gold is an inflation hedge originated,.... but it's not. Just look at the numbers since 1970. It's also not a good store of value; it's
way too volatile. And of course buying gold now, at the peak of one of the largest bubbles in gold's history, is a classic sign you don't know what you're doing.
But even aside from that, this particular portfolio is
way too heavily weighted towards "Mad Max" avoidance, and it doesn't even do that particularly well. In anything short of a full-out Thunderdome scenario, treasuries are just as safe and give better (i.e. any) returns. And who's going to buy gold in Thunderdome? If you're worried about that, buy ammo and bottled water -- and you can trade the water for as much gold as you like when people learn that gold is notorious for its lack of thirst-quenching ability.
If you're worried about inflation, buy TIPS. If you're worried about deflation, buy conventional bonds. If you want to assure growth, buy equities.
