GLOBAL MARKETS-Weaker growth, debt concerns send stocks lower

* World shares down 0.5 percent as growth worries resurface

* Weak German IFO business survey adds to economy concerns

* China Beige Book survey detects downturn in business

optimism

NEW YORK, Sept 24 (Reuters) - Stock markets and the euro

slipped on Monday as investors looked past recently announced

central bank stimulus plans to focus on weak German economic

data and the euro zone's unresolved debt crisis.

U.S. stocks followed the trend on the weak German report. A

China Beige Book survey detecting a downturn in business

optimism added to investor caution on the prospects for global

growth. The MSCI world equity index

fell 0.5 percent to 335.84.

"We've had such a strong quarter that it's difficult for us

to keep moving up, especially since we're so light on economic

news to trade on," said Oliver Pursche, president at Gary

Goldberg Financial Services in Suffern, New York. "We're maybe

in a sideways market without a lot of action for a while."

The Dow Jones industrial average was down 25.15

points, or 0.19 percent, at 13,554.32. The Standard & Poor's 500

Index was down 4.47 points, or 0.31 percent, at

1,455.68. The Nasdaq Composite Index was down 23.71

points, or 0.75 percent, at 3,156.25.

Apple Inc was a big mover in New York trade on news

it sold out of its new iPhone 5 smartphone, with the company

saying more than five million sold in the three days since it

hit stores. Apple shares fell 2.1 percent to $685.67 on

analysts' concern that the company was unable to produce the

phone fast enough to meet demand.

EURO EXTENDS LOSSES

The euro extended losses against the U.S. dollar after a

disappointing survey on German business sentiment and

uncertainty over Spain and Greece undermined the euro zone

common currency. The euro was last down 0.4 percent at

$1.2923 and has shed more than 1.5 percent from a four-month

peak reached on Sept. 17.

"German business sentiment as measured by the IFO dropped

further as investors remain reticent despite the European

Central Bank's 'bazooka' plan," said Christopher Vecchio,

currency analyst at Daily FX in New York.

The German data showed a drop in business sentiment for a

fifth successive month in September to its lowest level since

early 2010, showing even the strongest of Europe's economies is

succumbing to an economic downturn despite the European Central

Bank's recently announced bond-buying plan. European shares

lost 0.3 percent..

GROWTH WORRIES

Other parts of the currency market reflected concerns

surrounding global economic health. The growth-linked Australian

dollar slid as a rally sparked by recent central bank

stimulus moves ran out of steam, while the yen and the

U.S. dollar, traditional safety zones, both firmed.

U.S. debt prices rose as weak euro zone data encouraged the

buying of low-risk government bonds, with the health of the

struggling global economy at the heart of investors' concerns.

The yield on 10-year U.S. Treasury notes fell to

1.7163 percent from 1.755 percent in late U.S. trade on Friday.

Spanish debt worries remained the other dominant theme in

debt markets.

Madrid is expected to present its 2013 draft budget plan

this week and announce new structural reforms. The results of

stress tests on the Spanish banking sector are also due.

These could set the stage for a full-scale bailout although

European Union officials have said they do not expect Prime

Minister Mariano Rajoy to seek an assistance program before a

key regional election on Oct. 21.

The slow progress likely in Madrid is driving investors

gradually back into the safe-haven German debt market, pushing

the yield on 10-year safe Bund lower.

The main commodity markets also moved lower as the

disappointing German data and a firmer dollar pressured prices.

Brent crude futures for November fell $2.05 a barrel to

$109.37. U.S. crude was $1.56 lower at $91.33.
