The last time that I remember every single analyst talking about going long the US and short Europe was back in May 2010. I don’t know how to use Google Trends well enough, nor do I have access to a summary of all the research reports then and now to prove it, but that is my gut feel. I struggle to find anyone not saying that the US will outperform Europe. That reminds me so much of May 2010.
Here is what happened then
Over the course of the next couple of months the S&P underperformed Europe. SX5E is the Euro Stoxx 50 index, it is in EUR.
The IEV is an ETF that matches the Europe 350 index and is in dollars.
