More than half of the nation's underperforming 401(k)s can be found in the South, according to a ranking of the 10 worst states for 401(k)s by Judy Diamond Associates. 

The examination also found that two of the states on the list are among the most populous, with lots of employers sponsoring lots of plans. 

Arizona again claims the dubious distinction of finishing first, a repeat performance from last year. Slightly more than 16 percent of the 401(k)s plans in Arizona "significantly" underperformed an average benchmark, though the Grand Canyon State did see the largest year-over-year improvement. In 2014, 17.6 percent of plans in Arizona were identified as significant underperformers.
