Tech gains nudge S&P 500 and Nasdaq to further record highs

Strength for tech stocks nudged US indexes a bit further into record heights on Monday, more than making up for losses across much of the rest of Wall Street.

The S&P 500 rose 9.91 points, or 0.2%, to 4,290.61 after drifting between small gains and losses for much of the day. It added to its all-time high set Friday as optimism builds about the strengthening economy and expectations that the Federal Reserve will keep interest rates low for a while longer.
