With the markets still in a choppy/consolidation mode (or perhaps worse), it's best to consider including a few defensive stocks in your portfolio, and with the aforementioned in mind Smithfield Foods is worth an evaluation.

Smithfield Foods (NYSE: SFD) is the world's largest pork processor and hog producer. The company's products include fresh pork and processed meats sold under the Packerland, John Morrell, Lykes, Patrick Cudahy, and Smithfield Premium names.

Analysts expect Smithfield's F2008 revenue to increase 15-25% after a modest increase in F2007.

Meanwhile, beef margins are expected to widen, offsetting likely narrower hog margins. An improved product mix, including an expansion of value-added products, also has gladdened analysts' hearts.
