What helped Emerson Electric's stock advance in 2012?
Emerson didn't have the best 2011, falling about 15% in the wake of poor economic conditions around the world. The company's earnings miss in February shows some of the challenges that Emerson has had to face, as flooding in Thailand led to disappointing results. Yet that hasn't stopped the company from taking steps to bolster its long-term prospects through strategic acquisitions.

Emerson also hasn't been willing to rest on its laurels and coast on previous successes. Early this year, it said it would buy the marine container and boiler business of Johnson Controls (JCI 0.19%) to try to bolster its footprint to include meeting the heating and refrigeration needs of the shipping industry. Still, with Eaton (ETN -1.11%) having made a huge acquisition of electrical equipment maker Cooper Industries to boost its energy and power market exposure and with General Electric (GE -2.88%) having made big inroads toward elevating its energy infrastructure unit, Emerson and ABB (ABBN.Y 0.70%) both face huge competitors in their efforts to take advantage of the huge drive toward improving power grids and energy infrastructure.

Despite these challenges, Emerson delivered on a 56th consecutive annual dividend increase this November, boosting its payout by 3%. If the economy starts to get stronger around the world, its investors can expect 2013 to continue 2012's winning ways for its stock.
