A look at some of the key business events and economic indicators upcoming this week:

FEELING HEALTHY

UnitedHealth delivers its third-quarter results Tuesday.

The nation's largest health insurer is coming off a second quarter in which it made $2.28 billion and raised its forecast for 2017. The company has been plowing more resources into its Optum business, which provides pharmacy benefits management and technology services and also operates clinics and doctor's offices.

MIXED RESULTS?

Wall Street expects that Verizon Communication's latest quarterly snapshot will show mixed results.

Financial analysts predict the wireless carrier will report on Thursday that its third-quarter earnings declined from a year earlier, even as revenue rose. Verizon has been looking for new revenue sources as the wireless industry slows. It acquired Yahoo in June and combined it with a 2015 acquisition, AOL, into a content and ad business called Oath.

HOME SALES SLOWING

Economists project that sales of previously occupied homes declined for the fourth month in a row in September.

The pace of U.S. home sales slowed on a monthly basis since June, dampened by a worsening shortage of available properties and, more recently, the effects of Hurricanes Harvey and Irma. The National Association of Realtors is expected to report Friday that home sales slipped to a seasonally adjusted annual rate of 5.3 million last month.

Existing home sales, in millions, seasonally adjusted annual rate:

April 5.56

May 5.62

June 5.51

July 5.44

Aug. 5.35

Sept. (est.) 5.30
