Currency speculators went long against the US dollar in the latest week, according to Commodity Futures Trading Commission data released on Friday. The value of the dollar's net long position was $3.11 billion in the week ending January 26, reversing a net short position of $3.12 billion the previous week, according to Reuters calculations.

The last time speculators were long on the dollar was the week ending January 5. The Reuters calculation for the aggregate US dollar position is derived from the net positions of International Monetary Market speculators in the yen, euro, British pound, Swiss franc, Canadian and Australian dollars.
