Tech firms enjoyed a much-needed bounce on Thursday as they helped most Asian stock markets higher amid renewed hopes for the AI boom, though oil prices rallied after the US and Iran ratcheted up Middle East tensions.
Investor appetite for all things artificial intelligence has been tested in recent months on concern about elevated valuations and as they question when the trillions pumped into the sector will see returns, said AFP.
That has hammered a number of previously high-flying companies that have hit multiple records this year, particularly those in South Korea and Japan.
And an earnings report from Google-parent Alphabet on Wednesday raised fresh concerns as it said it would likely spend as much as $205 billion on AI this year, far more than expected.
Still, Asian traders took the opportunity to buy back into beaten-down stocks, with Seoul up more than four percent at one point, helped by rallies in chip giants SK hynix and Samsung, while Tokyo gained on the back of Advantest and Tokyo Electron.
Hong Kong, Sydney, Taipei, Manila and Jakarta also rose.
Next week's results from Microsoft, Meta and Amazon will be pored over for their capital spending plans.
"Big Tech does not need to stop spending for the earnings season to be positive. But the financial trade-off must improve," wrote Charu Chanana at Saxo Markets.
"The best results will come from companies showing that AI demand is turning into revenue, margins and cash flow.
"The next phase of the AI trade may reward those producing the highest returns from their infrastructure -- not simply those writing the largest cheques."
Traders are also growing increasingly nervous that the renewed strikes between US and Iranian forces could reignite inflation as oil prices creep higher.
Brent on Wednesday jumped more than three percent and broke back above $95 for the first time as President Donald Trump threatened to knock out one Iranian bridge or power plant in return for each attack on shipping in the Strait of Hormuz.
Foreign Minister Abbas Araghchi said Iran would respond in kind to any attack on its infrastructure, saying on X, "our defense doctrine is clear: eye for an eye".
Fighting over Hormuz, through which a fifth of world oil and gas usually passes, has collapsed a preliminary US-Iran peace deal, with Tehran reimposing its blockade and firing on vessels that seek to transit.
The prospect of higher oil prices putting upward pressure back on inflation has raised the specter of a Federal Reserve interest rate hike.
Investors will be looking at next week's policy meeting by the US central bank for some guidance on its plans. Money markets are pricing about a 30 percent chance of a rate increase, according to Bloomberg.
Adding to the uncertainty is the possibility of another global trade standoff after Trump's trade envoy Jamieson Greer signaled Tuesday that Washington was set to impose new levies on dozens of countries soon.
Eyes are also on Tokyo after the yen hit a fresh four-decade low against the dollar amid concerns at the Bank of Japan's slow pace of monetary tightening and speculation the Fed will hike soon, which would exacerbate an already wide interest rate differential.
Rising oil prices and concerns over the country's economy have added to pressure on the currency.
