Global stocks rallied Tuesday as the United States took a step away from imposing crushing restrictions on Chinese telecom company Huawei, while the pound gyrated on fresh Brexit drama.
Wall Street stocks gained ground following two straight losing sessions, with tech companies leading after the US Commerce Department announced it would delay implementation of a ban on Huawei for 90 days to allow companies to adjust their operations and avoid sudden disruption.
Nate Thooft, senior portfolio manager of Manulife Asset Management, said Huawei seems to be a "bargaining chip" in the broader US-China trade talks, raising concerns China could respond by targeting US tech companies.
Many analysts expect more volatility in markets ahead.
"We don't know what's going to happen on trade," Thooft said.
"Our baseline remains the view that basically there is going to be a trade deal. But the timeline is very questionable on when it's going to happen."
After falling on Monday, large tech companies such as Apple and Google parent Alphabet pushed higher, lifting the Nasdaq by 1.1 percent.
European bourses also rallied with the United States, while Asian markets were mixed.
The pound, meanwhile initially shot higher in anticipation of British Prime Minister Theresa May's latest Brexit announcement.
May, who has already said she will leave office next month, promised to give lawmakers a chance to set a confirmatory referendum on whatever version of Brexit they end up approving in the weeks or months to come.
But the pound later pulled back after critics attacked it as a rehash of earlier May efforts that have made little headway politically.
"The market was all geared up to hear something new," said Boris Schlossberg of BK Asset Management, adding said May's decision to link a second vote to her Brexit plan meant the announcement was a "warmed-over" version of a rejected idea.
"There was definitely a misreading of the headline first from the market," said Erik Nelson, a currency strategist at Wells Fargo.
"It seems that nothing has really changed with regards to Brexit and it is more likely today than it did yesterday that Prime Minister may well fail."
