I know we’ve discussed this ad nauseum, but is there any good (yet readable) literature out there on a good portfolio allocation for domestic vs. international equities?

The SmartMoney Asset Allocator recommends 20% international for me. That’s just crazy talk. I’m currently targeting 44% international, but I think that’s probably still way too low. (The rest: 18% commod, 9% US small, 20% US large, 9% tech.)

I would be happy to weight it by market cap, if I knew what US market cap was vs. international. Regardless, it seems like international (not just emerging markets) will outperform U.S. permanently, going forward. Thoughts on this?

Now I’m thinking something closer to 60% int’l. That would leave like 15% commod, 6% US small, 12% US large, 7% tech. But maybe THAT’S crazy?
