Apple's downward guidance two weeks ago, along with the announcements by Caterpillar and Nvidia, suggest the US-China trade war will affect more companies, said Kristina Hooper, chief global market strategist at Invesco.
"I view this as a cause for concern. It's not a crisis, but it's likely to be a few more canaries in the coal mine because there is going to be a significant cohort of stocks that are likely to be impacted by the US-China trade war," Hooper said.
Earnings at Chinese industrial firms shrank for a second straight month in December, hit by slowing prices and weak factory activity.

Volatility has picked up as investors fret about an economic cycle that is long in the tooth, leading to sharp reactions in the market to news, said Laura Kane, head of investment themes for the Americas at UBS Wealth Management.
Equity markets have solid underpinnings with fourth-quarter earnings looking good, a likely truce in the US-China trade talks and the Fed sounding a dovish message, leading her to be optimistic, Kane said.
"But the complication of volatility being uncomfortable and the fact we're later in the (business) cycle, that's why we're seeing these larger reactions to market news than we're used to," she said.
