McDonald's beats, Apple, Foxconn weighing US investment, Qualcomm falls after Apple suit

Here are some of the stocks the Yahoo Finance team will be watching for you today.

It’s a major week for Dow component earnings starting with McDonald’s (MCD). The fast-food giant delivered a slight beat on both its top and bottom lines for the fourth quarter thanks to better-than-expected same-store sales overseas and in the US. Worldwide comparable store sales climbed 2.7%, which was stronger than the 1.4% gain expected by analysts. Meanwhile, in the US, comparable store sales fell by 1.3%, but that was a little better than the 1.4% decline expected.

Some mixed results from Halliburton (HAL). The oil services provider reported adjusted earnings that topped analysts’ estimates, as a rise in crude prices encouraged oil producers to put more rigs back to work in North American shale fields. However, revenue fell nearly 21% from a year earlier, slightly missing forecasts for the fourth quarter

We’re also watching shares of our parent company Yahoo (YHOO) following news that the Securities and Exchange Commission is looking into whether Yahoo should have told investors about its two data breaches sooner. Yahoo disclosed both breaches after it agreed to sell its core business to Verizon (VZ) in July. Separately, the company is due to report fourth-quarter results after the close today.

Qualcomm (QCOM) shares are lower in early trading after losing more than 2% on Friday after Apple (AAPL) filed a lawsuit against the company accusing it of overcharging for chips and refusing to pay some $1 billion in promised rebates. This comes just days after the Federal Trade Commission accused Qualcomm of abusing its market dominance. Qualcomm denies the allegations.

In other news involving Apple, the tech giant may reportedly team up with its Taiwanese supplier Foxconn, which is considering investing $7 billion to build a flat-panel screen factory in the US. Foxconn’s CEO is quoted as saying Apple is willing to invest in the project because it needs flat-panel displays. Foxconn says the factory could create 30,000 to 50,000 American jobs and that discussions were under way with officials in Pennsylvania and other states. No comment yet from Apple.
