as investors awaited the unfolding effects of the September 11 attack. The Dow Industrials held on to last week's 7.4% gain, inching 12.60 lower to 8834.96. The Nasdaq Composite was weaker, falling 20.88 to 1477.92. Volumes were the lightest since the market reopened on Sept 17. Dealers said economic data had little effect on the market. The National Association of Purchasing Management's report for September showed surprising firmness but data within the report was not broken down by date of response, providing no clue to the effect of the Sept 11 attack. Also helping nerves was a snap-back in Tokyo, where the Nikkei reversed sharp losses to end 2% higher.//MarketNews
