The utilities sector just went through one of its roughest stretches in years, and for a sector built on stability, the sell-off may have caught many income investors off guard. The Utilities Select Sector SPDR Fund (NYSEARCA: XLU) tumbled to a 52-week low near $39, leaving the group more beaten down than it has been in almost three years. But something has shifted over the past several sessions. XLU has bounced nearly 5% off that low, trading back above $41, and the price action is starting to look like a bottom is forming.
