Semiconductor stocks crashed hard this summer, undoing much of the eye-popping gains they made earlier in the year. The Philadelphia Semiconductor Index, which had soared over 100% since January, fell into a bear market by July. Investors suddenly questioned whether the AI boom would drive enough chip demand to justify sky-high valuations.
The sector lost roughly $1.3 trillion in market value within weeks, an amount equivalent to Spain’s entire GDP. Heavyweights like Nvidia, the poster child of AI chips, fell about 2.5%. Broadcom grappled with disappointing guidance, rattling investors who expected flawless growth. Memory chip producers Micron and SK Hynix also gave back months of gains as enthusiasm cooled.
Overcrowded trade and uncertainty collide
Multiple forces converged to snap the AI chip rally. Fund managers grew skeptical about sustained AI capital spending. Rising interest rates and ongoing geopolitical risks compounded worries about fragile tech supply chains. According to a July survey by Bank of America, 82% of fund managers called semiconductors the most crowded trade in the market.
This reversal starkly contrasts with Bitcoin’s quieter performance, which dropped 33% during the same period even as chip stocks doubled. As the AI chip frenzy unwinds, many money managers appear to be shifting toward sectors with steadier prospects, such as transportation and biotech.
