June 9 (Reuters) - U.S. stocks fell on Thursday morning, led by financials and as lower oil prices weighed on energy companies.
Oil prices were down 1.5 percent as traders took profits after a three-day rally.
The S&P financial index was down about 1 percent, while the energy index fell 0.7 percent.
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 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."
At 9:57 a.m. EDT the Dow Jones industrial average was down 44.89 points, or 0.25 percent, at 17,960.16.
The S&P 500 was down 6.84 points, or 0.32 percent, at 2,112.28, distancing itself from its record high of 2134.72 in May last year.
The Nasdaq Composite was down 12.45 points, or 0.25 percent, at 4,962.20.
Six of the 10 major S&P sectors were lower, led by financials. Bank of America and Wells Fargo both were down about 2 percent.
Chesapeake Energy fell 5 percent to $4.72 after an RBC downgrade. Other energy stocks also dropped with oil prices.
