Stocks moved sharply lower last week after third quarter earnings failed to live up to investor expectations. According to FactSet, more than three-quarters of S&P 500 companies that reported third quarter earnings had positive earnings surprises, and more than half reported positive revenue surprises. However, most companies offered negative fourth quarter earnings guidance, which caused shares to move lower.

Tech stocks were especially hard hit amid concerns of a slowdown, with Amazon.com, Inc. (AMZN) and Alphabet Inc. (GOOGL) missing expectations. But even industrials giants like Caterpillar Inc. (CAT) and 3M Company (MMM) missed expectations. Many investors are wondering if the strong fundamentals seen earlier this year are starting to wane in recent months.

Traders will be keeping a close eye on consumer confidence data due on Oct. 30, ADP employment data on Oct. 31, ISM manufacturing index data on Nov. 1, and of course non-farm payrolls due out on Nov. 2. Investors will also be keeping a close eye on any new developments in the U.S.-China trade war that continues to take a toll on the market.
