Coca-Cola, Caterpillar, Greece Boost Futures

U.S. stock index futures are pointing to a higher open Tuesday morning on some positive news from two key Dow components.

The indication higher comes a day after a last-hour selloff pushed the Dow to its first close below 10,000 since November, and the S&P 500 to a fresh three-month closing low as well.

Part of the morning's more bullish tone also was sparked by European Central Bank President Jean-Claude Trichet, who cut short a trip to Australia, prompting speculation that initiatives are in the works to help resolve Greece's debt problems. An ECB spokesperson said the change of plan was only due to logistics.

In earnings news, Dow component Coca-Cola posted a profit of 66 cents a share, in line with estimates and enough to send its shares up 2 percent in premarket trading.

Fellow Dow component Caterpillar saw its shares climb about 4 percent permarket on an upgrade from Morgan Stanley.

And McDonald's shares climbed nearly 1 percent after the company reported a 2.6 percent gain in monthly sales for January.

Technology shares also looked broadly higher, with the Nasdaq likely to gain 1 percent off the opening bell.

Toyota announced the long-rumored recall of 437,000 Prius and other hybrid models to fix a braking problem. Toyota shares have rallied about 3 percent overseas this morning, but they're still about 20 percent below where they were when the latest recall crisis began in late January.

In other earnings, Pulte Homes reported a smaller loss and said excluding items the builder operated at breakeven for the quarter. Shares gained 1.5 percent premarket.

After this afternoon's closing bell, Dow component Walt Disney will be out with its quarterly numbers.
