CPI Spike Fuels Fed Rate Hike Fears, Stocks Tumble
11 Jun
Summary
- Annual inflation hit 4.2%, reigniting rate hike discussions.
- SpaceX IPO caused significant investor fund reallocation.
- Allegro MicroSystems and Sensata Technologies saw stock drops.

The stock market experienced a notable downturn in the afternoon session following the release of a 4.2% annual inflation print, the highest since 2023. This data revived discussions of a potential Federal Reserve rate hike later in the year.
Market participants began fully pricing in a December Fed rate hike. Semiconductor stocks, particularly sensitive to changes in discount rates, faced significant repricing. Additional pressure came from the impending SpaceX IPO, with the company closing investor orders at a substantial $1.77 trillion valuation.
MSC identified chip names among holdings likely to face forced outflows as investors shifted capital to fund the SpaceX listing. Furthermore, geopolitical tensions escalated as former President Trump pledged to "attack very hard" in Iran, contributing to a risk-off sentiment that drove the Dow to session lows.
Among the affected companies, Allegro MicroSystems (NASDAQ:ALGM) fell 4.7%, and Sensata Technologies (NYSE:ST) declined by 5%. Sensata Technologies, despite a year-to-date gain of 34.9%, was trading 12.1% below its 52-week high of $53.55 as of June 2026.
