UPDATE 1-Speculators cut net U.S. dollar longs in latest week-CFTC, Reuters

(Adds table, details on dollar and euro contracts)
    Dec 11 (Reuters) - Speculators reduced bullish bets on the
U.S. dollar in the latest week, according to Reuters
calculations and data from the Commodity Futures Trading
Commission released on Friday.
    The value of the dollar's net long position slipped to
$41.22 billion in the week ended Dec. 8, from $43.47 billion the
previous week. Speculators have trimmed their net long position
on the dollar for a second straight week.
    The U.S. dollar index has risen more than 8.0 percent so far
in 2015, boosted all year by expectations that the Federal
Reserve would be the first major central bank to raise interest
rates this year.
    In fact, markets have fully priced in a lift-off next week,
and the only issue being debated is the number of rate increases
over the next few years.
    In other contracts, speculators cut their short position on
the euro, with 172,331 contracts, from 182,845. 
    The decline was expected especially in the wake of the
European Central Bank's stimulus package announced last week
that came in below market expectations. The ECB decision had
resulted in a big jump in the euro, rising as much as 3.0
percent, on the day of the announcement last Thursday.
    On the year though, the euro was down more than 9.0 percent 
against the dollar. Many in the market had predicted that the
euro will slide to parity against the dollar because of the
divergence in monetary policy between the Fed and the ECB. 
    However, parity between the euro and the dollar has yet to

position is derived from net positions of International Monetary
Market speculators in the yen, euro, sterling, Swiss franc and
Canadian and Australian dollars.
