Dow, S&P 500 end lower on profit-taking

Strength in semiconductors boosts Nasdaq

The S&P 500 and the Dow closed with slight losses on Monday after briefly touching intraday records, but strength in semiconductors boosted the Nasdaq.

Monday's subdued trading followed the Dow's biggest weekly gain since January 2013 and the S&P's biggest two-week jump since December 2011. Gains in recent weeks have largely come on the back of strong quarterly results, which have eased concerns over how corporations are faring in an uncertain global economy.

"We got back to the highs in the S&P 500 and Dow rather quickly, so I think you're running into some resistance and profit-taking," said Stephen Carl, principal and head of US Equity Trading at The Williams Capital Group.

In the latest economic data, US construction spending fell 0.4% in September, well below expectations. However, manufacturing activity unexpectedly accelerated in October and automobile sales were strong, easing concerns of a significant moderation in economic growth.
