Nvidia, AMD and Intel Lead Semiconductor Selloff as AI Rally Investors Take Profits

Semiconductor stocks fell sharply on June 17, with AMD down 7.3%, Intel 8.5%, Micron Technology 6.2%, Broadcom 4.4%, and Nvidia 2.4%. The broader S&P 500 rose 0.33% on the same session, underlining a selective rotation out of the sector rather than a broad market retreat.

What Happened

The declines came after months of strong gains driven by investor expectations for sustained artificial intelligence infrastructure spending. GPU and chip makers ranked among the strongest performers in 2026, with Nvidia’s data-centre revenues expanding on demand from hyperscalers including Amazon Web Services, Microsoft Azure, and Alphabet’s Google Cloud.

Profit-taking accelerated as the sector reached elevated valuations relative to historical earnings multiples. SpaceX, which listed on Nasdaq on June 13, gained 4.8% on the same session, reflecting a rotation in which fresh capital moved toward the newest public listing while veterans of the AI rally gave ground.

Key declines on June 17:

• AMD: -7.3%
• Intel: -8.5%
• Micron Technology: -6.2%
• Broadcom: -4.4%
• Nvidia: -2.4%

Why Portfolio Concentration Matters

Semiconductor stocks have been one of the primary drivers of equity returns for investors in 2026. Technology-weighted portfolios and AI-themed ETFs absorbed significant single-session drawdowns even as broader indices held positive.

Year-to-date inflows into US-listed ETFs reached $830 billion as of late May 2026, much of it concentrated in large-cap technology products. The concentration that produced strong first-half returns also created meaningful exposure to sharp single-sector reversals.

For investors tracking net worth across multiple asset classes, including public equities, private holdings, and fixed income, a single-session move of 7-8% in a core holding creates a real shift in total portfolio value. Concentration risk that looks manageable during a prolonged rally becomes concrete when a sector reverses.

What to Watch

Whether this selloff marks a temporary correction or the beginning of a broader rotation depends on forthcoming earnings data. Several major semiconductor companies report quarterly results in the next four weeks, and any softening in data-centre revenue guidance could extend the declines.

The Fed’s decision on June 17 to hold rates at 3.50-3.75% kept monetary conditions stable. The updated June dot-plot, released today, shows multiple FOMC members now projecting rate hikes in the second half of 2026. If implemented, higher rates would compress the forward earnings multiples that have supported semiconductor valuations throughout the year.

Investors with concentrated AI-chip positions should monitor guidance revisions when Nvidia, AMD, and Intel report quarterly results in July.
