* Oil price falls on high U.S. inventories
* Euro rises vs dollar after German bond auction (Updates with U.S. markets)

NEW YORK/LONDON, Aug 18 (Reuters) - World stocks resumed their bearish run on Wednesday after tepid earnings reports from some big U.S. companies and energy shares fell as crude oil prices remained under pressure after a disappointing industry report.
The euro rose against the dollar after a German government bond auction attracted solid demand, easing some concerns about fiscal instability in the European Union.
Oil prices pared losses after a government report showed U.S. crude stocks last week fell less than analysts had expected. That news undercut some of the pressure on prices after a report late on Tuesday from the American Petroleum Institute that showed a rise in crude stocks last week.
On Wall Street, shares fell back a day after rallying more than 1 percent, as investors grappling with the direction of the economy assessed the latest corporate earnings.
Retailers were again in focus. Discounter Target Corp. reported weak same-store sales but its shares rebounded from earlier losses after the company said it would open 20 or more new stores next year and more than 30 in 2012.
"You're hearing more of the same from the retailers that the second half appears it might not be the easiest. While consumers may be coming to the stores just as often, it doesn't seem to be they're spending any more," said Kurt Brunner, portfolio manager at Swarthmore Group in Philadelphia, Pennsylvania.
Also on Wednesday, warehouse club operator BJ's Wholesale Club Inc <BJ.N> missed profit expectations, sending its shares down 4.2 percent at $41.50. Target <TGT.N> gained 1.8 percent to $51.59 after earlier losing about 3 percent. The rebound lifted the consumer discretionary sector and helped indexes come off their lows.
Also on the earnings front, Deere & Co <DE.N> beat estimates, but said sales were "far below normal levels" and pointed to deteriorating conditions in Europe. Deere lost 1.4 percent to $66.26. [

"The market is still rangebound. There is no conviction at the moment, and this will go on until September when investors come back from holiday," said Alexandre Le Drogoff, technical analyst at Aurel BGC in Paris.
The dollar endured selling pressure against the yen, easing toward recent 15-year lows on growing speculation that Japanese authorities are unlikely to intervene to counter their currency's recent strong run.
The euro recovered from the day's low after a 5 billion euro sale of German 10-year debt produced a record-low average yield of 2.37 percent.
Sterling rose after the the release of minutes from the Bank of England's policy meeting earlier this week showed officials were less dovish than expected.
The dollar shed 0.3 percent against the yen to 85.25 yen <JPY=>, not far from a 15-year low of 84.72 yen hit on trading platform EBS last week. The euro declined 0.12 percent at $1.2879 <EUR=>.
U.S. Treasury bond prices gained as the decline in equities refreshed concerns about economic strength.
The 30-year bond surged more than a point in price to yield 3.70 percent, down from 3.77 percent at Tuesday's close and a fresh 16-month low. Longer-dated German bonds rallied after Berlin drew strong demand at a 5 billion euro sale of new 10-year paper at a record low average yield.
