There are three driving factors: first, renewed market concerns about the sustainability of AI capital expenditures; second, profit-taking in the memory sector after Micron's earnings, spreading to upstream equipment and back-end testing/packaging; third, institutional portfolio rebalancing at quarter-end hitting high-beta stocks. From a sector perspective, valuations on the supply side of the AI computing chain remain relatively high, and a pullback is a necessary pressure release, not the end." datetime: "2026-06-29T10:18:36.000Z" locales: - [en](https://longbridge.com/en/topics/42277884.md) - [zh-CN](https://longbridge.com/zh-CN/topics/42277884.md) - [zh-HK](https://longbridge.com/zh-HK/topics/42277884.md) author: "[没有观点是观点](https://longbridge.com/en/profiles/27445273.md)" generator: "portal-rs" --- # The U.S. stock semiconductor equipment/testing and… ### Related Stocks - [CRDO.US](https://longbridge.com/en/quote/CRDO.US.md) - [TSEM.US](https://longbridge.com/en/quote/TSEM.US.md) - [TXN.US](https://longbridge.com/en/quote/TXN.US.md) - [AMKR.US](https://longbridge.com/en/quote/AMKR.US.md) - [TER.US](https://longbridge.com/en/quote/TER.US.md) - [AEHR.US](https://longbridge.com/en/quote/AEHR.US.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
