Oil closed above $99 per barrel Tuesday after major banks raised their forecasts for crude prices. Energy companies including Chevron Corp. and Exxon Mobil Corp. rose, but most other industries fell.

Greece's main opposition party said it opposed the government's latest attempts to reduce debt. The news further dampened hopes that Greece would repair its finances.

The Dow Jones industrial average rose 25 points, or 0.2 percent, to close at 12,356. The S&P 500 index fell 1 point to 1,316. The Nasdaq fell 13, or 0.5 percent, to 2,746.
