S&P 500 Energy Stocks Post First-Quarter Loss

The first-quarter earnings season is almost over, and it's one most investors would like to forget. But by far the most notable feature: The energy sector has recorded its first year-over-year quarterly loss in the 17 years that Standard and Poor's has tracked data for the sector.

Overall, S&P energy companies have reported an average decline of 35 cents per share, down nearly 107 percent from the same quarter last year, according to S&P Global Market Intelligence.
