S&P 500 barely rises as investors await key results, jobs data, Fed meeting

The S&P 500 closed barely higher after choppy trading session as investors held their breath ahead of a raft of big technology company earnings, a Federal Reserve policy decision on interest-rate cuts and key US labor data, all due this week.

A bruising selloff in U.S. stocks is putting a sharper focus on valuations of the tech names such as Nvidia and Microsoft that have driven markets higher for most of this year. Despite a recent pullback, the S&P 500 tech sector is trading near a two-decade high reached earlier this month.
