There's an article in The Economist that calls for $1.80 for a Euro over the longer term based on some estimates that the dollar is still 30% overvalued.
Wouldn't that mean stocks would have to appreciate at least 30% to maintain value for foreign investors? Europeans could have beat this whole 2-year "bull" market in US stocks by sitting in cash or bonds denominated in Euros http://finance.yahoo.com/q/bc?s=EURUSD=X&t=2y&l=on&z=m&q=l&c=spy
