Technology companies led the stock market to its third straight loss Thursday after an earnings report from Cisco Systems raised more questions about the economy.

A weekly employment report that was weaker than expected also made investors uneasy about the strength of the economic recovery. The Dow Jones industrial average fell 58 points and now has an almost 380-point loss the past three days. The Dow has also fallen five of the last six days. The Nasdaq composite index had a steeper loss in percentage terms, a reflection of the drop in tech stocks.
