The euro zone economy has grown slower than many had expected in the first part of this year. And, if you add to that, inflation which is still hovering below 1-percent. Those two factors combined will likely put pressure on the European Central Bank to ease monetary pressure at their next meeting in June. But, Sameer Samana, senior international strategist at Wells Fargo Advisors, says investors may be disappointed because he doesn't believe the ECB will move more aggressively until its September meeting. The ECB has said a strong euro is one of its concerns because of the downward pressure it puts on import prices and exports. Samana believes the euro will likely weaken slightly by the end of summer.
