Marginal Stock Advances After A Tricky Day

News of terror attacks in Saudi Arabia contrasted with strong manufacturing growth and a rise in construction spending created a jittery, seesaw trading session Tuesday. The major indexes all finished slightly higher for the day.

An attack on foreign oil workers in Saudi Arabia, the only OPEC nation with excess production capacity, killed 22 people and caused crude-oil prices to spike again, up $1.87, to $41.75.
