On June 11, ARM Holdings fell 3.04% in after-hours trading, trading at $298.87/share, with trading volume of $290 million. The decline extends a multi-day correction that has intensified following Wall Street warnings over extreme valuation levels.

On the news front, ARM has rallied approximately 97% in recent weeks, pushing its forward price-to-earnings ratio above 170x and price-to-sales ratio to approximately 67x — the highest among S&P 500 constituents on the latter metric. Multiple Wall Street firms have issued bubble warnings, with Roundhill Investments CEO noting that buyers at current levels are effectively betting on earnings delivery in 2030. Additionally, Broadcom's disappointing AI chip sales outlook has weighed on broader semiconductor sentiment, pressuring the entire sector.

Within the Semiconductor sector, the broader group declined in recent sessions. Among individual stocks, Micron Technology down 2.25%, NVIDIA down 0.34%, Broadcom down 1.28%, Marvell Technology down 3.40%, Intel down 1.71%.
