Speculators trim U.S. dollar longs for 2nd week -CFTC, Reuters data

June 27 (Reuters) - Speculators further pared bets favoring the U.S. dollar in the latest week, according to data from the Commodity Futures Trading Commission released on Friday.

The value of the dollar's net long position slipped to $11.34 billion in the week ended June 24, from longs of $12.19 billion the previous week. Net U.S. dollar longs have declined for a second straight week.

To be long a currency is a view it will rise, while being short is a bet its value will decline.

The week also saw a decline in the euro's net short position to 57,503 contracts from 61,835 the previous week. That coincides with the euro still trading north of $1.35 versus the dollar despite the European Central Bank's announcement of stimulus measures a few weeks ago to lift a sluggish euro zone economy. Late on Friday, the euro was up 0.3 percent at $1.3647.

Short-term investors also reduced long positions on the pound, to 49,751 contracts from 52,596. This was just a position adjustment after longs got to extreme levels. Sentiment on the pound remained upbeat as the Bank of England is expected to be one of the first central banks in the developed world to raise interest rates.

The Reuters calculation for the aggregate U.S. dollar position is derived from net positions of International Monetary Market speculators in the yen, euro, sterling, Swiss franc and Canadian and Australian dollars.
