(In August 13 item, corrects 6 paragraph to remove reference to sterling positions)
NEW YORK, Aug 13 (Reuters) - Currency speculators increased net short dollar positions in the latest week, data from the Commodity Futures Trading Commission showed on Friday.
The value of the dollar's net short position was $17.82 billion in the week ended Aug. 10, up from a net short position of $15.5 billion in the previous week, according to CFTC and Reuters data.
Speculators had been long the dollar for most of 2010 but the weekly report of July 13 showed speculators started to bet against it for the first time since the week ended March 16, when value of the net short position was just $121 million.
The last time the value of the dollar's net short position was larger than this week's position was in the week to Dec. 1, according to Reuters calculations.
The Reuters calculation for the aggregate U.S. 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.
Speculators were still betting against the euro. They increased long positions on the yen, Canadian dollar and Australian dollar. Meanwhile, they cut short positions on the euro and went long on sterling.
