JP Morgan's First Quarter Market Bulletin for 2015 provides a recap of the earnings season.
"In Brief
• We estimate that first quarter 2015 earnings-per-share (EPS) declined by 5.0% on a year-over-year (y/y) basis. Similar to the prior quarter, this was primarily due to lower oil prices and the stronger U.S. dollar (USD).
• Excluding the energy sector, S&P 500 EPS grew by 9.1%, in-line with historical trends. We also estimate that the stronger U.S. dollar resulted in an average EPS decline of 5% for the most multinational non-energy companies.
