Is now a good time for individual investors to reduce exposure to crowded semiconductor stocks?

In September 2026, global fund managers identified semiconductors as the most crowded trade for the fourth straight month. However, conviction in the sector cooled significantly, falling to 53% from a July peak of 82%.

Why it matters

AI-driven demand from companies like Nvidia and AMD fueled the sector's growth, but rising bond yields are now forcing investors to reconsider the high discount rates applied to future earnings.

The iShares Semiconductor ETF posted a 99% year-to-date gain as of mid-June 2026. During the July 2026 survey period, 210 managers overseeing $555 billion reported net overweight technology positioning of 18%.

The players

Bank of America

This global financial institution conducts regular surveys of fund managers to gauge sentiment on asset classes and economic risks.

Nvidia

Nvidia is a dominant technology company known for designing graphics processing units that are essential for artificial intelligence development.

AMD

Advanced Micro Devices is a major semiconductor company that competes in the data center and consumer electronics processor markets.

Taiwan Semiconductor

Taiwan Semiconductor Manufacturing Company is a leading global foundry that produces chips for many of the world's largest technology firms.

The details

Despite believing valuations are stretched, fund managers have maintained long positions in the chip sector. The concern regarding an AI bubble has grown, with 45% of managers citing it as a top tail risk in July, up from 28% in June.

Timeline

  1. April 2026 saw 25% of managers label the sector as a crowded trade.

  2. May 2026 marked a rise to 73% of managers identifying the crowded trade.

  3. June 2026 included a survey of 198 managers managing $540 billion in assets.

  4. July 2026 represented the peak of conviction at 82% among 210 surveyed managers.

  5. September 2026 showed a decline in conviction to 53% for the crowded trade.

The Tech Race

This cooling of sector conviction reflects a broader reassessment of the AI-driven tech boom that dominated the first half of 2026. Investors are balancing the immense demand for advanced processing power against the economic realities of higher discount rates and valuation concerns.

Retail investors holding semiconductor-heavy portfolios may experience increased volatility as professional fund managers rotate capital out of overcrowded positions. This shift highlights the importance of monitoring institutional risk sentiment when managing tech-heavy investments.

The takeaway

Investors should remain cautious as professional fund managers signal a cooling period for once-crowded semiconductor trades. Diversifying holdings beyond high-growth AI stocks can help mitigate the risks associated with rapid valuation swings in the tech sector.
