What Were the Top Ten Most Preferred Stocks in 2014?

The top 10 most preferred stock in 2014 included Southwest Airlines, Delta Air Lines, Electronic Arts, Edwards Lifesciences and Allergan, according to Kiplinger. Rounding out the list were Mallinckrodt, Avago Technologies, Keurig Green Mountain, Royal Caribbean Cruises and Kroger.

Southwest Airlines was one of the best stocks of 2014 because the airline allows passengers to check bags for free and does not charge for changing flights at the last minute, explains Kiplinger. Lower fuel expenses helped to raise Delta Air Lines stock values by 79 percent.

Electronic Arts, the producer of gaming systems and games, had a good 2014 because of the Xbox One and PlayStation 4, with profits up 75 percent. Experts estimate an even bigger profit margin in 2015. Another top stock in the technology field is Avago Technologies, a company that produces a wide range of electronic components and acquired LSI Corporation in 2014.

Edwards Lifesciences is a health care stock in the top 10 of 2014 that rose 94 percent, says Kiplinger. Part of this company's success was due to the valve implants it started producing. These valves are used to make heart surgery less invasive and dangerous.

Mallinckrodt and Allergan are two other health care stocks on the list. Mallinckrodt started making a drug, Acthar, that treats a range of health conditions, such as lupus.
