NEW YORK, Aug 19 (Reuters) - Wall Street finished lower on Wednesday after the Federal Reserve raised concerns that the U.S. economic recovery from the devastating effects of the pandemic faced a highly uncertain path.
In the minutes of the July Fed meeting, the policy committee said that swift rebound in employment seen in May and June had likely slowed and that additional "substantial improvement" in the labor market would hinge on a "broad and sustained" reopening of business activity.
It also ruled out for now more dovish monetary policy measures such as the yield-curve control.
"The Fed was cautious in the minutes and has been over the last month," said Mike O’Rourke, chief market strategist, Jones Trading. "I think the fact that the Fed was not too warm on the yield-curve control and some of the extreme measures investors may have liked to see was a concern."
Unofficially, the Dow Jones Industrial Average fell 0.3% to end at 27,694.46 points, while the S&P 500 lost 0.44% to 3,374.96.
The Nasdaq Composite dropped 0.57%, to 11,146.46.
Earlier in the session, the S&P 500 hit an intraday record of 3,399.54 and Nasdaq of 11,257.422.
Apple Inc became the first publicly listed U.S. company to cross $2 trillion in market capitalization. Already the most valuable listed company in the world, the iPhone maker provided the biggest support to the three main indexes.
The company's stock was boosted by expectations of long-term success from the country's biggest tech names in a post-coronavirus world.
Strong results from retailers Target and Lowe's also lifted sentiment earlier in the session.
The S&P 500 closed at a record on Tuesday in what has been its fastest recovery ever from a bear market. The Nasdaq recouped its losses from the pandemic sell-off two months ago, but the Dow is still nearly 5% below February's record closing high.
