Asian shares trade mixed after Wall Street rally despite Iran war worries

Asian shares traded mixed as Wall Street rally optimism clashed with anxiety over surging oil prices and a possible AI bubble, with Japan's Nikkei 225 adding 0.6% and South Korea's Kospi dropping 2.7%. The US-Iran war continues to impact oil prices, with benchmark US crude rising to $99.64 a barrel. The global economy remains dependent on a few AI leaders, creating a fragile rally structure.
