Asian Chip Stocks Slump as Broadcom Outlook Triggers Tech Selloff in Nikkei and Kospi

Amid growing scrutiny over the sustainability of the tech rally, Asian semiconductor stocks faced a sharp selloff following disappointing sector guidance. Japan's Nikkei index fell 1.3%, while South Korea's Kospi experienced a significant slide of more than 6%. The downturn was triggered by Broadcom's AI chip outlook, which failed to meet high market expectations, leading to a 5% drop in Samsung shares and a 7% decline for SK Hynix.

This regional slump reflects broader pressure on the global tech sector, as Broadcom's recent quarterly results showed semiconductor revenue growing 12% to $7.2 billion, missing some analyst estimates per Bloomberg data. Compared to previous quarters, Asian chipmakers are seeing a reversal of early-year gains as investors reassess AI valuations against a backdrop of geopolitical tensions and high interest rates.

Investors should watch key support levels for Asian benchmarks, with the Nikkei 225 (1306.T) showing weakness as of the June 5, 2026 close. Looking ahead, upcoming catalysts include speeches from Fed officials Kashkari and Schmid, which may influence market sentiment regarding interest rate paths and their subsequent impact on high-growth technology valuations.
