By Caroline Valetkevitch NEW YORK, Jan 10 (Reuters) - U.S. stocks ended higher on Tuesday on relief that Federal Reserve Chair Jerome Powell refrained in a speech from commenting on rate policy. Recent comments by other Fed officials have supported the view that the central bank needs to remain aggressive in raising interest rates to control inflation. Analysts expect overall S&P 500 earnings to have declined 2.2% in the fourth quarter from a year ago as worries about rising rates and the economy mount, according to IBES data from Refinitiv.
