Investors hedge against euro falls

US investors spooked by the caving euro are getting their hedges on the currency.

A record $203m (€178m) was added to the iShares Currency Hedged MSCI Eurozone ETF earlier this week, a fund that outperforms when the single currency weakens. The same day, four massive block trades, which appear to be sells, hit the tape for the Vanguard FTSE Europe ETF.
