while the Nasdaq ended off almost 61 points but volumes were light. Tone for the day was set by UK electronics firm Marconi which saw its stock hammered by over 50% after its dramatic profit warning overnight. That news depressed US tech issues leading to the spread of red ink. Dow losers included Boeing (announced small sales in June) as well as GM, GE, Home Depot, Microsoft and Walmart. Bucking the trend, SBC Communications and Honeywell posted gains. On the Nasdaq, losers included Dell, Sun-Micro, Symantec, Nextel and Veritas Software all traded down on the day. S&P 500 ended down 15 points.
