Broadcom guidance shock stalls AI rally; Indonesia rout hits Asia

On 5 June Broadcom’s weaker-than-expected semiconductor revenue forecast sent the stock down about 14–15% in U.S. premarket trading and triggered a broad selloff across technology and cybersecurity names. CrowdStrike fell about 10% and Nasdaq futures slid more than 1% in early Asian trade. The Nasdaq 100 briefly printed an intraday record before breaking below a short-term ascending channel; market technicians identified 30,535 as a short-term pivot, with potential supports near 30,000, 29,700 and 29,410 and resistance in the 30,728–30,795 area.

Indonesian equities and the rupiah plunged after the government took direct control of key commodity export flows. The benchmark stock index has fallen about 36% from its high five months ago and the rupiah has weakened more than 7% as foreign investors withdrew from stocks and bonds. Traders described a widening “sell Indonesia” trade that weighed on regional risk appetite. The South Korean won weakened to roughly 1,545 per dollar, its weakest level since 2009, and authorities in Indonesia and the Philippines increased interventions to support their currencies.

While U.S. technology names fell, the Dow Jones Industrial Average rose about 875 points as energy prices eased and investors rotated into industrials, financials and other value sectors. West Texas Intermediate crude futures fell around 3% to near $93 a barrel after reports of possible progress on ceasefires and diplomatic talks in the Middle East; some diplomatic efforts met setbacks. Short-dated U.S. Treasury yields retraced, with the two-year yield down about four basis points to near 4.05% and the 10-year around 4.48%.

Regional equity indices reflected the split between tech weakness and sector rotation. South Korea’s KOSPI fell as much as 5% intraday, the Nikkei 225 dropped about 1.6%, the Hang Seng fell roughly 0.8%, Australia’s ASX 200 declined 0.7% and Singapore’s STI eased 0.3%. The MSCI Asia Pacific index lost between 0.8% and 1.3% as technology names underperformed.

Currency and commodity moves influenced flows across markets. The U.S. dollar index slipped about 0.1%; the euro strengthened intraday to roughly $1.1645 before settling near $1.1611. The Japanese yen briefly firmed to about 159.7–159.9 per dollar before moving back toward 160. Spot gold rose about 0.9% but remained below its short-term moving average.

Market participants cited a reassessment of near-term revenue prospects for semiconductor and AI-related firms and heightened sensitivity in emerging markets to interventionist trade and export policies as factors behind the volatility. Investors were also watching upcoming U.S. labor data and developments in U.S.-Iran diplomacy for potential impact on interest-rate and oil-price expectations.
