June 9 (Reuters) - Wall Street was set for a lower open on Thursday as a drop in oil prices more than offset strong weekly labor market data.
The number of Americans filing for unemployment benefits unexpectedly fell last week, pointing to sustained strength in the labor market despite a sharp slowdown in hiring last month.
The jobless claims data gave investors their first read of the labor market since Friday when dismal May payrolls numbers jolted the markets.
Still, a more than 1 percent decline in oil on Thursday kept stock futures under pressure.
Traders took profits, ending a three-day rally in oil prices that was spurred by a weak dollar. The dollar has fallen since the monthly jobs report reduced the chances of an interest rate hike in the near term.
The weaker dollar not only boosts commodities, but is beneficial to U.S. multinationals that derive a large portion of their sales from overseas.
The contrasting fortunes of oil and the dollar have spurred a rally in stocks for the past three days.
The Dow closed above the 18,000 mark on Wednesday for the first time since April, while the S&P 500 is less than 1 percent shy of its record intraday high.
"There is no fresh catalyst to drive the markets higher, even though it's a stone's throw away from record highs," said Andre Bakhos, managing director at Janlyn Capital LLC in Bernardsville, New Jersey.
"This shows some nervousness over the quality of the rally."
