Wall Street opens flat after data, Cisco soars

U.S. stocks were little changed at the open as a rally in Cisco Systems was offset by weak data on the labor and housing markets.

Cisco soared 11.6 percent to $23.64 a day after reporting quarterly results.

The Dow Jones industrial average was down 4.78 points, or 0.03 percent, at 15,270.91. The Standard & Poor's 500 Index was down 2.23 points, or 0.13 percent, at 1,656.55. The Nasdaq Composite Index was up 3.48 points, or 0.10 percent, at 3,475.10.
