LONDON, Nov 8 (Reuters) - The euro fell broadly on Monday on renewed concerns about euro zone peripheral debt, while investors trimmed short dollar positions built up before the U.S. Federal Reserve eased monetary policy last week.

Solid U.S. jobs data on Friday [ID:nN04265378] also helped the dollar recover as it assuaged concerns the Fed may opt for more quantitative easing than it announced on Wednesday and led many to conclude that bad news was fully priced into the dollar.

With the Fed's decision to launch more QE out of the way, euro zone debt worries have reappeared on traders' radars, while weak German industrial output data [ID:nBZN8ME63Q] triggered more euro selling.

Analysts were not all convinced the euro's pullback against the dollar would be too deep, however, with Fed QE remaining a negative for the dollar. Although $1.40 may now provide stiff resistance, support was seen at the November low of $1.3860.

"We've had a bit of a post-QE hangover and a refocusing on strains in the euro zone," said Kit Juckes, currency strategist at Societe Generale.

"This is a correction and not more. The dollar and the euro have different problems, but they both have problems."

The euro was down 0.8 percent against the dollar at $1.3919, having hit a low of $1.3892, according to Reuters data, its lowest in a week. Traders reported stop loss orders on a break of $1.3880.

Below the $1.3860 November low, more support was seen at $1.3835, the 76.4 percent retracement of the Oct. 20 to Nov. 4 rally to a 10-month high of $1.4283. Some saw a fall towards $1.3750, just below the late October low of $1.3756.

"We don't see a massive sell-off of the euro nor do we expect a mad sell-off of the dollar. The market is caught between the impact of the Fed's QE and euro zone debt problems," said Daragh Maher, deputy head of FX research at Credit Agricole CIB.

G20 MEETING

Analysts also said traders may be cautious about chasing the dollar much higher ahead of the Group of 20 summit meeting in Seoul later this week, which may address imbalances.

"Now that QE by the Fed has become a fact, the market is paying attention to other factors that were overshadowed ahead of the Fed meeting," said Roberto Mialich, currency strategist at Unicredit in Milan.

The euro fell 1.1 percent against the yen to hit the day's low of 112.65 yen, according to Reuters data. It also fell 0.6 percent against the pound to 86.19 pence .

The dollar fell 0.2 percent against the yen to 81.06 yen but remained above its 15-year low of 80.21 yen plumbed last week as the U.S. currency gained broadly.

Versus a currency basket, the dollar <.DXY> was up 0.7 percent at 77.102. The higher-yielding Aussie dollar was down 0.5 percent at $1.0110, off Friday's 28-year peak of $1.0183, and the New Zealand dollar fell 1.1 percent.
