No beef. And "preposterous statement" was in reference to the OP.
USD has strengthened against several currencies including the Euro for about nine months now, pretty much since The Fed indicated to markets that it was approaching time to hike rates. Combine this with (Shiller) PE, Market Cap to GDP, etc all the usual indicators pointing to the fact that there are no bargains to be had at home for US investors, PLUS the fact that if you were just rebalancing by putting a fixed amount into a 50/50 domestic/international portfolio over the last 12 months almost all of it would have gone into international*, and I'd say that "international markets are on sale, and have been for a while, but won't be forever" is a fair statement. That's all I'm saying.
*assuming say a 100K portfolio, adding $1000/month
