S&P 500 ends lower after recent gains
Based on the latest available data, the Dow Jones industrial average was up 2.27 points, or 0.02 percent, at 12,042.43. The Standard & Poor's 500 Index was down 3.58 points, or 0.27 percent, at 1,304.01. The Nasdaq Composite Index was down 1.03 points, or 0.04 percent, at 2,750.16.
The index is starting to look overbought again after touching 2-1/2-year highs Tuesday. A key measure of the rally's strength suggests stocks are vulnerable to a correction, analysts said.
The PHLX Semiconductor Index is running into resistance around 450, a level not surpassed since 2007. Chips are considered a leading indicator for the broader market.
