Global Stocks Fall as AI Rally Pauses, Iran Talks Stall

​

June 5, 2026 — Global equity markets moved lower on Friday as investors pulled back from technology stocks following a sharp decline in Broadcom shares, while uncertainty surrounding U.S.-Iran negotiations added to market caution. Asian stocks led the decline as traders locked in profits from the recent AI-driven rally.

The shift in sentiment came after Broadcom reported results that fell slightly short of elevated market expectations, triggering a broad selloff across semiconductor stocks and raising questions about the sustainability of the artificial intelligence boom that has fueled global markets this year.

Broadcom Results Weigh on Chip Sector

Broadcom's quarterly revenue came in at $22.19 billion, slightly below analysts' expectations of $22.27 billion, prompting investors to reassess valuations across the semiconductor industry. The company's shares fell sharply, dragging down other AI-linked chipmakers.

The weakness spread across Asian markets, particularly in South Korea, where major semiconductor stocks faced heavy selling pressure amid broader concerns about the technology sector.

U.S.-Iran Uncertainty Adds to Market Jitters

Investor sentiment was also affected by uncertainty surrounding efforts to reach a diplomatic resolution between the United States and Iran. Conflicting signals regarding negotiations and ongoing regional tensions encouraged a more defensive stance heading into the weekend.

Markets remained sensitive to developments in the Middle East due to concerns about potential implications for global energy supplies and inflation.

Yen Near Intervention Zone Again

In currency markets, the U.S. dollar strengthened and briefly approached the 160 yen level, a threshold closely watched by investors because of previous intervention by Japanese authorities. The move renewed speculation that Tokyo could take action if volatility increases further.

Oil Heads for Weekly Gain

Oil prices remained relatively stable during Friday trading but were still on track for a weekly gain of more than 3%, supported by concerns over geopolitical developments and potential supply disruptions in the Middle East.

Despite the latest pullback in equities, investors continue to monitor both AI-related growth trends and geopolitical developments as the primary drivers of global market sentiment.
