"No one is really surprised," said Jay Suskind, director of trading at Ryan Beck & Co. "The market whisper was that they would show more concern about inflation."
"The market rallied back up because the flipside is that this means the economy is doing well enough and earnings will stay strong," Suskind said.

Fed clocks in
According to Carl Weinberg, chief economist at High Frequency Economics, markets were "universally positioned" for the Fed decision, and that the only risk was that the central bank would be more bearish on the economy than expected.
In its policy statement, the Fed repeated the key statement that it could choose to move rates in either direction depending on the data even though inflation risks remain the paramount concern.
The Fed made only a few changes from its March 21 statement. In a nod to the weak first quarter growth rate of 1.3%, the Fed said growth had slowed, and adjustments in housing were ongoing, but it maintained its outlook for the economy to continue growing at "a moderate pace."
The Fed had already predicted "moderate growth" at the end of last year, "just before growth slowed to the first quarter's paltry 1.3%," said Ian Shepherdson, chief U.S. economist at HFE.
"Bottom line: Until the unemployment rate starts to move or payrolls tank, they're on hold," he wrote in a note, adding that he expects the Fed to start cutting rates in August.
