HONG KONG (Nikkei Markets) -- Hong Kong shares edged lower after a choppy trading day on Monday amid heightened caution over protests in the city and U.S.-China trade war tensions.
The Hang Seng Index fell 0.4% to 25,824.72 after changing direction at least seven times. HSBC Holdings fell 1.6%. The London-headquartered lender's Greater China CEO Helen Wong is resigning to pursue a job at another company. Wong's departure follows an announcement by the bank earlier in the week that Global Chief Executive John Flint would be stepping down from his position.
Sunny Optical Technology Group added 3.6% after reporting a 23% increase in July shipment volumes for handset lenses and an 82.2% jump in shipments for handset cameras.
Cathay Pacific Airways slid 4.9% to HK$9.80, its lowest closing level since June 2009, while Swire Pacific slumped 6.2%. The Civil Aviation Administration of China on Friday barred some of Cathay's crew who had joined or supported protests in Hong Kong from working on any flight services to the mainland. The regulator also asked the airline to submit a list of crew members for approval starting Aug. 11, for all flights to and from the mainland and any that cross Chinese airspace.
"Not only is this likely to affect direct China flights, but also flights to Europe and, to a lesser extent, to the U.S., given they fly over China airspace," Jefferies analyst Andrew Lee, wrote in a note.
He said the CAAC flight safety warning added to the near-term headwinds facing the airline.
Swire Pacific is Cathay's single largest shareholder, with a 45% interest in the company, according to Refinitiv.
Trading volumes in the city were weaker than usual, with shares worth about 58.78 billion Hong Kong dollars ($7.49 billion) changing hands.
Protests in Hong Kong continued for the 10th straight weekend, with demonstrations again turning violent on Saturday and Sunday, as police fired tear gas in the streets and in a train station to clear crowds.
Activists continue to demand that the government withdraw its controversial extradition bill, conduct an independent investigation into the police's use of force during the demonstrations and implement universal suffrage.
Meanwhile, trade tensions between the U.S. and China showed few signs of easing after U.S. President Donald Trump on Friday said the U.S. was not ready to make a deal. A round of trade talks is expected to take place in Washington early in September. Trump suggested the meeting might not take place.
"With political instability in Hong Kong, people worry economic development will slow down, while the trade has been escalating," said Banny Lam, managing director and head of research at investment corporation CEB International. "We are not hearing good news from either side. It seems there is no way out of the stalemate."
