As the three above charts show, returns on the big 3 European ETFs have been essentially zero for the past 15 years. This is typical of a secular bear market, zero return with extreme volatility throughout. I think the picture going forward will be quite different.
Germany (EWG) is pushing up on resistance established at the 2000 peak, the breakdown period in 2007-08 which lead to the global financial crisis and the 2011 peak established prior to the European Debt Crisis. We could see some more sideways movement before finally moving higher but I think the lows are in.
France (EWQ) is sitting on major support established in 1998-99, 2006 and more recently in 2011. The United Kingdom (EWU) has a similar chart. Both are sitting on key Fibonacci retracement lines.
