AI and semiconductor stocks drop sharply amid investor concerns over valuations and demand.

Semiconductor stocks have fallen for eight straight sessions, marking their steepest decline in years, with the Semiconductor Index dropping 24% since mid-June while the S&P 500 gained 2%. This decline, reminiscent of the post-dot-com bubble period, reflects investor worries about whether AI-related spending will deliver sufficient returns amid rising borrowing costs and uncertain demand. Global technology equity funds saw $4.8 billion in outflows, suggesting a rotation away from tech stocks despite overall market inflows. The future trajectory depends on whether AI earnings and cash flows justify current valuations, with a sustained demand potentially leading to a market correction, while disappointing returns could cause a prolonged downturn.

As of Oct 20, 2026 19:43 WIB, Micron Technology (MU) trades at USD 887.00 on Pluang, down 1.98% for the day, reflecting some of the caution seen in semiconductor stocks. The stock's market cap stands at $1.02 trillion with a typical hold time of 49 days among Pluang investors. This aligns with the broader sector's recent struggles, highlighting investor uncertainty in technology amid the AI spending debate.
