It is a bit that the model predicts on one hand the American index rise, on the other hand the descent of the dollar exchange rate with the euro. For an European investor it is a magic moment, because he/she may invest with a sort of safety net and gaining from two fronts with just one investment.
The principal instrument for an European investor are ETFs on the indexes, not hedged against the EurUsd exchange risk. Apparently, and also in certain moments, you are getting a double risk: one on the stock exchange index and one on the currency exchange. But the global long term effect is that you cumulate a rise in the stock index with a reduction of the EurUsd rate.
Of course, here I do not suggest any direct investment: contact your consultant and ask for a professional advice.
