Stocks were lower Tuesday as third-quarter earnings season barreled forward with a dump of quarterly reports.

The S&P 500 was down 0.26%, the Dow Jones Industrial Average fell 0.2%, and the Nasdaq slid 0.4%.

Nearly one-third of S&P 500 companies have reported earnings so far this season. Of those that have reported 75% have beat earnings estimates, above the historical average of 64%, while 60% have beat sales forecasts. The third-quarter blended earnings growth estimate is 1.7%, according to Thomson Reuters, on track to snap the longest earnings recession in seven years.

"Should these patterns hold, it will mark the end of the earnings recession largely caused by the rising dollar/falling oil trends," Robert Doll, senior portfolio manager and chief equity strategist at Nuveen Asset Management, wrote in a note.

Caterpillar (CAT) - Get Report  was a major drag on the Dow after forecasting little growth next year. The manufacturing equipment company said it expects full-year 2017 revenue "not significantly different" than its 2016 projections. The company anticipates 2016 revenue to come in at $39 billion, below consensus of $40.1 billion. Analysts had anticipated fiscal 2017 revenue to climb to $39.27 billion.

Under Armour (UA) - Get Report slumped 13% after warning of slowing growth in coming quarters. The company's "growth rate going forward will be less than expected," executives said in remarks on an earnings call Tuesday. The workout apparel retailer reported a 28% increase in third-quarter profit, while revenue rose 22%. Earnings-per-share of 29 cents came in higher than estimates of 25 cents.

Other apparel brands such as PVH Corp (PVH) - Get Report , Ralph Lauren (RL) - Get Report , Hanesbrands (HBI) - Get Report and VF Corp (VFC) - Get Report fell, while the Consumer Discretionary SPDR ETF (XLY) - Get Report slid 0.9%. Cyclical consumer goods stocks were the worst performers on Tuesday.

Investors also showed their nerves ahead of quarterly earnings from Apple (AAPL) - Get Report , the world's largest company and the biggest weight on the S&P 500. The tech company will report after markets close on Tuesday. The recent launch of the iPhone 7 and Samsung's recent troubles with its Note 7 are expected to boost sales.

However, the company is still expected to report its third straight quarter of declining revenue for the iPhone. Recent checks on Apple Watch sales also suggest weakness. An IDC report showed Apple shipped 1.1 million Apple Watches over the third quarter, a massive 71% drop from the same period a year earlier.

"Iraq is insisting on an exemption so that it can fund its war against the terrorist militia IS," Commerzbank analysts wrote in a note. "It seems somewhat unlikely that the other OPEC states will agree to this. After all, this would ultimately mean that Saudi Arabia and its allies in the Gulf Region would bear the brunt of the burden given that Libya, Nigeria and Iran already look set to be exempted from production cuts. This makes the kind of agreement on concerted production cuts that was announced with such fanfare at the meeting in Algiers seem a long way off."

West Texas Intermediate crude was down 1.1% to $49.96 a barrel on Tuesday afternoon.
