Energy Futures--U.S. crude-oil futures passed $100 a barrel after a gauge of U.S. manufacturing came in higher than expected and spurred hopes of increased crude demand. A weaker dollar and lingering geopolitical concerns surrounding Iran also supported prices. In midafternoon Tuesday trading, crude-oil futures for February delivery rose $3.92, or 4%, to $102.74 a barrel on the New York Mercantile Exchange, keeping close to session highs. The contract had traded as high as $102.88 a barrel earlier.
