Market news for July 28, 2026: Asian chip stocks tumbled today, led by a 10.84 per cent drop in South Korea's Kospi, which triggered a circuit breaker. The sell-off reflected growing concerns over elevated AI valuations and rising competition from China. At the same time, Brent crude continued to fall on hopes of easing geopolitical tensions between the US and Iran.
