London (AFP) - Stock markets mostly climbed on Wednesday as investors digested a wave of company earnings that have broadly surpassed expectations, while assessing the chances of a US-Iran deal to reopen the Strait of Hormuz.

A few minutes into trading on Wall Street the Dow was up 1.2 percent at 54,592.44 points while the broader S&P 500 and the tech-heavy Nasdaq both gained – despite a 12 percent fall for Elon Musk’s Space X.

Musk’s rocket and satellite company slid after posting its first quarterly earnings report, amid questions on what returns huge investments on artificial intelligence will ultimately produce.

While revenues jumped 92 percent, investors focused on the more than $18 billion in SpaceX spending during the quarter.

In Europe, London, Paris and Frankfurt all made modest gains around two hours from the close, as oil prices edged slightly higher after Yemen’s Iran-backed Houthis said they had attacked a Saudi oil tanker in the Red Sea.

Frankfurt and Paris had joined Madrid and Milan in hitting fresh highs earlier in the session.

London’s FTSE 100 index was weighed down by a six-percent drop in HSBC shares as analysts said investors were disappointed by the size of the bank’s share buyback announced Tuesday.

But Swiss resources giant Glencore rose almost four percent in London after it reported a return to profit in the first half of the year.

Asian equities benefited from a recent revival in technology stocks after a month-long rout, tracking gains on Wall Street on Tuesday that sent both the Dow and the S&P 500 to new records.

Seoul, which has been at the forefront of extreme volatility in the tech sector over the past month, while Tokyo was up more than three percent and Hong Kong and Shanghai also saw gains.

Oil ticked higher after falling sharply on Tuesday after US Treasury Secretary Scott Bessent said a deal could be reached imminently with Tehran on re-opening the Strait of Hormuz to shipping traffic.

But “fresh attacks and threats from the Houthi rebels on Saudi’s oil export from the Red Sea” rattled confidence in a lasting Hormuz deal, said analysts at DNB Carnegie.

Investors are also keeping tabs on this week’s release of US jobs data that should provide a fresh idea about the state of the economy, and guide the Federal Reserve as it considers its next move on interest rates.
