Fed Decision Looms as Nasdaq 100 Rebalancing Triggers Turmoil in Tech Stocks

The tech benchmark slips below 30,000 as traders brace for the Fed’s rate announcement and a sweeping Nasdaq index overhaul on June 22, triggering massive portfolio shifts.

The Nasdaq 100 is being pulled in two opposite directions this week. While traders brace for the Federal Reserve’s interest-rate announcement, a sweeping index overhaul set for June 22 is already forcing massive portfolio shifts. The result: a volatile session that saw the tech benchmark slip below the psychologically important 30,000 mark.

Semiconductor stocks bore the brunt of the selling pressure. Advanced Micro Devices tumbled more than 5%, while Micron and Broadcom also suffered heavy losses. Microsoft and NVIDIA added to the downside, though Alphabet and Apple managed modest gains, and Amazon clung to the positive side. The divergence signals a clear rotation away from high-flying chip names into more defensive growth stocks.

The market’s attention now turns to Washington. At 2:00 p.m. Eastern Time, the Federal Reserve is expected to hold its benchmark rate steady in a range of 3.5% to 3.75% — a near-certain outcome. Half an hour later, Fed Chair Kevin Warsh steps before the press, and his tone on future policy will set the tone for the weeks ahead. The CBOE Volatility Index has already climbed above 16, reflecting heightened uncertainty.

Compounding the Fed anxiety is the impending reconstitution of the index itself. On June 22, the Nasdaq will reshuffle its composition, promoting AI-driven winners and ejecting legacy names. The resulting rebalancing has triggered a wave of forced buying and selling. Charter Communications suffered its worst trading day since 1999, crashing 18.5% after missing earnings per share expectations by $9.18. Zscaler and Cognizant also declined, the former facing an internal probe alongside its index removal.

On the flip side, stocks destined for inclusion are surging. Western Digital jumped nearly 10%, having more than quadrupled year-to-date. CoreWeave climbed above $117, fueled by an analyst report pointing to a $131 billion order backlog. Astera Labs gained 5.7% after announcing new AI labs in Taiwan, while Nebius Group and Rocket Lab also posted strong gains. The rotation among passive funds is expected to continue into the weekend, keeping volatility elevated for affected names.

Beyond the Fed and index mechanics, broader markets are finding relief from geopolitical developments. Brent crude slipped below $80 a barrel on hopes of a US–Iran peace agreement, easing supply fears and potentially reducing inflationary pressure. The 10-year Treasury yield held steady at 4.44%, while gold stayed above $4,300. Meanwhile, a disappointing housing report showed US housing starts fell 15.4% in May to their lowest level in four years, adding another layer of caution.

Technically, the Nasdaq 100 is at a critical juncture. A sustained break below current levels could open the door to the 29,700 support zone, with the 50-day moving average further down. On the upside, the week’s high near 30,600 remains a stubborn resistance that must be cleared for any quick recovery. The index closed Tuesday at 30,121, leaving a year-to-date gain of 19% still intact — but the next 24 hours will test whether that rally has further to run.
