Sony warns of big loss; FedEx delivers a beat; General Mills misses estimates

Here is a look at some of the stocks the Yahoo Finance team will be watching for you today.

FedEx (FDX) shares were higher in early trading. The package delivery company reported profits and sales that topped analysts' estimates thanks to strength in its express and ground businesses. The company also said yesterday it will raise shipping rates in the U.S. on average by 4.9% in January.

General Mills (GIS) fell before the bell. The company known for its Cheerios cereal and Betty Crocker cake mix reported earnings that missed estimates by $0.08. Quarterly profit fell 25% and sales also came in below expectations. The company is citing challenging U.S. market conditions and other factors for the shortfall. Earlier this month, the company said it would buy Annie's to expand its presence in the natural-and-organic-foods aisles.

Sony (SNE) stock tumbled in early trading after the Japanese consumer electronics company warned of a bigger-than-expected loss for the year of more than $2 billion as its smartphone business continues to bleed red ink. The company also said it would not pay a dividend this year for the first time since going public in 1958.

Adobe Systems (ADBE) shares were lower in the pre-market. The maker of Photoshop said that revenue for this quarter would be weaker than analysts' expected after reporting revenue slightly missed estimates last quarter as sales in its digital media business declined. However, earnings per share beat Wall Street's views.

DuPont (DD) shares rose ahead of the open on news that Nelson Peltz's hedge fund is calling for a breakup of the chemical giant.  The stock is up more than 10% in the past year as of yesterday's close, but Peltz's fund is arguing that DuPont's businesses are too diverse for one company.
