FXstreet.com (Barcelona) -Euro saw the largest change in investor positioning vs. USD, entering net long territory for the second week in a row, notes Nomura FX strategists.

Nomura expands: "Since the data was collected on Tuesday, EUR has strengthened by over 1% vs. USD, but surprisingly, our real-time estimates show that investors have not added to net EUR long positions by a significant amount since Tuesday."

"EUR net longs rose by $2.3bn in the week ending Tuesday, bringing the euro to an overall net long position of $3.6bn. This is the largest net long position in EUR since the first week of July 2011" the bank adds.
