HONG KONG (AP) — Asian stocks mostly advanced Friday, helped by buying of technology-related shares, while oil prices slipped as traders watched for developments in the Iran war.

Tensions between Iran and the U.S. escalated this week after President Donald Trump said the Iran war ceasefire agreement was “over” and as the United States and Iran exchanged attacks.

Australia’s S&P/ASX 200 gained 0.5% to 8,806.00.

India’s Sensex added 1%.

Oil prices yo-yoed again on Friday as global oil supplies remained under pressure due to a limited numbers of vessels able to cross the Strait of Hormuz, a crucial waterway for energy transport.

Brent crude, the international standard, fell 0.8% to $75.66 per barrel. It was trading near $72 a barrel before the war began in late February.

On Thursday, Wall Street’s benchmark S&P 500 index rose 0.8% and the Dow Jones Industrial Average gained 0.3%. The technology-heavy Nasdaq composite climbed 1.3% to 26,206.89.

Semiconductors stocks led gains. Micron Technology jumped 4.5% after the memory chipmaker said it would increase its U.S. investments, citing “surging demand for memory in the AI era.”

Shares of AMD, or Advanced Micro Devices, surged 5.7%. Marvell Technology rose 5%, while ON Semiconductor added 4.4%.
