On Monday, resistance proved futile to downward pressure rather than to upside momentum for a change. The combination of Friday's reversal, Motorola's ( MOT) warning and a shake-up at Freddie Mac ( FRE) sent major stock proxies lower, although traders' propensity to buy weakness surfaced yet again. The Dow Jones Industrial Average fell 0.9% to 8980, after trading as low as 8945.59 late in the session. The S&P 500 slid 1.2% to 975.93 after trading as low as 972.59, while the Nasdaq Composite shed 1.4% to 1603.97 vs. its nadir of 1597.30. Although declining stocks led advancers by about 2 to 1 in both Big Board and over-the-counter trading, optimists took solace, because volume was down considerably from last week's levels. About 1.3 billion shares traded on the Big Board and 1.8 billion in Nasdaq trading, indicating somewhat decreased activity on the downside.
