(Reuters) - The S&P 500 and the Dow hit record highs on Thursday as easing inflation concerns boosted demand for richly valued technology stocks, while upbeat earnings reports and strong March retail sales raised hopes of a broader economic rebound.
The S&P information technology and communication services indexes, which include Apple Inc, Microsoft Corp and Facebook Inc, led gains after underperforming last month.

"While individual names may sell off, the overall sector is fine."
