Wisconsin Energy (NYSE:WEC) Could Double Investors' Returns Says FBR

Citing their algorithm, FBR Capital said the worst-performing utility from the previous month has about a 60 percent chance of outperforming the utility index and can at times double the returns. Wisconsin Energy (NYSE:WEC) was last month's worst performing utility.

FBR said, "Wisconsin Energy was last month's "biggest loser." Based on our algorithm, if investors buy the prior month’s worst-performing utility, the stock will tend to outperform the utility index roughly 60% of the time and potentially double their returns. November's "biggest loser," NextEra Energy, outperformed our utility index by 45 bps in the following month. In December, the worst-performing utility was Wisconsin Energy."
