(AP Photo/Lee Jin-man)BANGKOK -- South Korea’s Kospi index jumped more than 16% on Friday, tracking gains on Wall Street as artificial intelligence-related stocks bounced back after losses earlier this week. The Kospi index had sunk more than 17% in the previous three days as investors dumped technology stocks in part over worries about an AI bubble and rising competition from chipmaking and AI rivals in China. Hong Kong's Hang Seng edged 0.1% higher, to 25,894,21, while the Shanghai Composite index advanced 0.6% to 3,828.00. It was trading near $72 a barrel before the Iran war began in late February.
