Boeing's stock last traded up 5.7% for the session. — Jesse Pound

Data from scheduling firm Homebase, which tracks small and medium businesses, shows that business conditions worsened in September. The firm said in its monthly report that the number of hours worked, employees working and businesses open were all lower in September than a comparable period in August. 

This marks the first time Homebase has shown a decline in employment metrics since the pandemic recovery began. The decline could be due in part to the Labor Day holiday and seasonal factors, the report said. — Jesse Pound

Gold is suffering its worst week in at least six, with both spot and future prices hovering around $1,865 as the dollar strengthens. Technical analyst Frank Gretz from Wellington Shields said in a note that this slide means that it will take time for gold to climb back toward its recent highs.

"Gold has enjoyed a great run this year, including record highs in August. Since then Gold had been in a narrow 30 day trading range, forming what used to be called a triangle pattern," Gretz said. "Historically, there has been a high probability of an upside resolution in comparable patterns for Gold. After this week, this apparently isn't one of them. While the overall uptrend remains intact, it will now take time to rebuild the pattern." — Jesse Pound, Reuters

At the same time, the technology-heavy Nasdaq Composite is on pace to close the week in the red.

Barclays upgraded shares of Royal Caribbean, Carnival Corp. and Norwegian Cruise Line to overweight from equal weight on Friday, lifting the stocks in premarket trading.

"While we may be early, we believe the risk/reward is the most attractive in our coverage universe," Barclays analyst Felicia Hendrix told clients. "Investors who have previously written off cruise stocks should begin to revisit their models."

Next week, the Centers for Disease Control and Prevention will address the no-sail date for the industry. While Barclays said there is a high probability the CDC will extend the no-sail date in the fourth quarter, the Wall Street firm believes "the comments from the agency will be positive and could signal a near-term return to cruise, which could be a catalyst for the shares," said Hendrix. 

Barclays also raised all three of the cruise stocks' 12-month price target. — Maggie Fitzgerald

Shares of Costco were under pressure on Friday, falling 2.6% in the premarket even after the big-box retailer reported quarterly earnings that beat analyst expectations. Costco reported earnings per share of $3.04 on revenue of $53.38 billion. Analysts expected a profit of $2.84 per share on revenue of $52.08 billion, according to Refinitiv.

Futures contracts tied to the major U.S. stock averages slid on Friday, implying there might be more selling to round off a rough week on Wall Street. Dow Jones Industrial Average futures slid 0.8% suggesting a 180-point loss at the open. S&P 500 futures fell 0.6%, while Nasdaq 100 futures declined by 0.36%.

The major averages are on track for their fourth straight week of losses for the first time since Aug. 2019. An uptick in coronavirus cases has pressured stocks this week, as has investor rotation away from some of the high-flying technology names and lack of second stimulus progress from Congress. - Pippa Stevens
