Wall Street ends flat as commodities weigh

Wall Street finished little changed on Monday as a better-than-expected start to corporate earnings season boosted investor confidence, but gains were curbed by a drop in commodities. Shares of technology companies were among the bright spots, helping the tech-heavy Nasdaq Composite to its third straight record close as investor focus shifts to earnings from Greece and China. The top five boosts to the S&P 500 were from the tech sector.
