Wall Street ends flat as banks gain, Apple drags

The Fed is expected to leave interest rates unchanged at the two-day meeting, but investors will assess Chair Janet Yellen's speech on Wednesday to see if the central bank plans to hike as soon as December.

It’s been driven by the threat of higher interest rates," said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa.
