TOKYO (Reuters) - Asian shares slid on Thursday, led by falls in South Korean tech shares, as investors locked in recent gains after Wall Street's Dow Jones Industrial Average broke the 22,000 barrier for the first time in its 121-year history.
Spreadbetters expected European stocks to follow suit, predicting Britain's FTSE and Germany's DAX to both open about 0.1 percent lower while forecasting a flat open for France's CAC.
MSCI's broadest index of Asia-Pacific shares outside Japan dropped 0.6 percent, with South Korea's tech-heavy Kospi index on course to drop 1.6 percent.
"We haven't seen a major correction in tech shares so far this year so they may be hitting a speed bump," said Nobuhiko Kuramochi, chief strategist at Mizuho Securities.
Samsung Electronics, which last Friday posted its biggest daily fall since October, slid 2.3 percent, giving up the gains made so far this week. SK Hynix dropped 2.9 percent.
"Those shares that were bought heavily on Tuesday are being sold aggressively. I would suspect investors want to take profits quickly after they saw a sharp correction last week," said Yukino Yamada, senior strategist at Daiwa Securities.
Some Seoul shares took an additional hit from President Moon Jae-in's new tax plan.
Japan's Nikkei dropped 0.3 percent.
In New York overnight, the Dow Jones Industrial Average topped the 22,000 mark for the first time on the strength in Apple shares following its earnings.
The S&P 500 gained 0.05 percent, hovering just below its record high touched last week, supported by upbeat earnings and rising expectations that the Federal Reserve's policy tightening will move ahead only slowly.
"The stock markets are supported by steady growth in earnings," said Mutsumi Kagawa, chief global strategist at Rakuten Securities, noting steady growth in forward earnings in the United States, Japan and elsewhere.
"In addition, even as the economy grows, both policy interest rates and long-term interest rates remain low because inflation remains tame due to various structural reasons," he added.
U.S. inflation has been contained even as the country's labour market appears to be in its best shape in many years, with the jobless rate staying near a 17-year low.
A report by private payrolls processor ADP showed on Wednesday that private U.S. employers added 178,000 jobs in July, slightly below economists' expectations, although payroll gains in June were revised up to 191,000 from an originally reported 158,000.
Market participants expect the more closely watched government employment report due on Friday to show a solid expansion in U.S. job creation.
In the currency market, the dollar has been losing its lustre as the euro zone and a few other countries have been slowly winding back stimulus.
The European Central Bank, which is buying 60 billion euro ($71 billion) bonds per month to shore up euro zone economies, is expected to unveil a plan to wind down the asset purchase programme in coming months.
The euro traded at $1.1845, after having risen to as high as $1.19105 on Wednesday, its highest level since January 2015.
The common currency has strengthened sharply against the safe-haven Swiss franc, having gained more than four percent in less than two weeks to 1.1488 francs.
The British pound held near its highest in almost 11 months against a broadly weaker dollar ahead of the Bank of England's "Super Thursday", which could shed light on how soon interest rates could be lifted.
Sterling has been supported in recent weeks by expectations the bank might finally be getting ready for a hike after a series of hawkish comments from policymakers, though Governor Mark Carney could be more cautious.
The pound last traded at $1.3221 , near Wednesday's 11-month high of $1.3250.
The yen stepped back from Tuesday's 1 1/2-month high of 109.92 yen per dollar to trade at 110.69 yen .
Oil prices dipped as a rally that pushed up prices by almost 10 percent since early last week lost its momentum, despite renewed signs of a gradually tightening U.S. market.
While strong demand in the United States supported prices, ongoing strong supplies from OPEC producers restricted further gains.
Brent crude futures slipped 0.4 percent to $52.17 per barrel, still not far from Wednesday's high of $52.93, its highest level in 10 weeks.
