The most recent three-month range is expected to show another decline in S&P 500 earnings, though a shallower drop than recent reporting periods.
"Expectations are that earnings will improve in this quarter although they may still be negative," Dan North, chief economist at Euler Hermes North America, told TheStreet. "A trailing [price-earnings ratio] of 20 is inflated, and earnings growth had better come soon. We may well get that growth in 2017 if we see a return to growth in the energy sector due to a base effect."
S&P 500 companies are expected to report a 0.8% decline in aggregate third-quarter operating earnings, according to Sam Stovall, chief equity strategist at S&P Global Market Intelligence. Another drop would mark the fifth quarter in a row of earnings declines, a recession not seen since 2009. Consumer staples, financials, materials and utilities are expected to post growth, while the energy sector will continue to be a drag. Excluding energy, earnings growth would likely be 2.5%.

Crude oil prices declined Tuesday, pulling back from a rally of more than 1% seen a day earlier. Prices had jumped on Monday after Russian President Vladimir Putin said the country would participate in the Organization of Petroleum Exporting Countries' plan to limit production. Russia is not part of OPEC, though frequently joins discussions over production.
OPEC agreed to limit production at a meeting last month in order to correct a supply glut and recover from the commodity market's multi-year lows. However, production remains at record highs as individual countries struggle to rein in output. OPEC oil production increased by 160,000 barrels to 33.6 million barrels per day in September, according to the latest International Energy Agency monthly report.
West Texas Intermediate crude oil closed down 0.99% at $50.84 a barrel.
