U.S. stocks trimmed an advance as Apple Inc. fell for a second day to weigh on technology shares, while a rebound in banks lost some momentum as investors awaited key policy meetings for the Federal Reserve and Bank of Japan this week.
The S&P 500 Index climbed 0.2 percent to 2,142.90 at 12:24 p.m. in New York, after rising as much as 0.7 percent. Apple fell 1.3 percent, wiping out an early 1.1 percent gain.
Asian shares edged lower on Tuesday as investors nervously waited on the outcomes of the Federal Reserve and Bank of Japan policy meetings that begin later in the session.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was slightly lower in early trading, after major U.S. indexes ended a choppy session nearly flat.
Japan's Nikkei stock index .N225 shed 0.5 percent, as trading resumed after a public holiday on Monday. Tokyo markets will be closed for another holiday on Thursday, with the highly-anticipated BOJ meeting sandwiched in between the market closures.
