The stock market opened lower this morning, recovered some ground around noon, but deteriorated as the session progressed. At the end of trading, the Dow Jones Industrial Average was down 99 points; the broader S&P 500 Index was off 20 points; and the NASDAQ was lower by 101 points. Market breadth showed a negative bias, as decliners easily outpaced advancers on the NYSE. The technology sector weighed heavily on the market. However, it should be noted that this group of volatile stocks may have been overdue for some profit taking. In addition, the healthcare and utility issues were quite weak. In contrast, the energy and financial names managed to make positive strides.
