Sept 25 (Reuters) - U.S. stocks were set to open slightly lower on Monday, weighed down by a drop in Apple shares and heightened expectations of another interest rate hike this year following comments from a Federal Reserve official.
The central bank is on track to gradually raise interest rates as factors depressing inflation are fading and the U.S. economy’s fundamentals are sound, New York Federal Reserve President William Dudley said.
Investors are also awaiting a speech by Fed Chief Janet Yellen later in the week for more guidance on the monetary policy.
“Investors would like to get more clarity as far as what the Fed is going to do as they move forward with the unwinding of the balance sheet and how they are going to move forward next year,” said Robert Pavlik, chief market strategist at Boston Private Wealth in New York.
