On June 15, ARM Holdings rose 3.6% in regular trading, trading at $393.9/share, with turnover of $2.423 billion. The stock extended its multi-day rally as semiconductor stocks collectively strengthened across the board.

Storage concept stocks also surged, with Micron Technology, SanDisk, and Western Digital rising in tandem. The rally followed ARM's 11.27% surge on June 12, driven by strong sector-wide momentum in semiconductors and continued investor enthusiasm around AI infrastructure buildout. ARM's Neoverse architecture adoption by major cloud providers and its data center royalty revenue doubling year-over-year have reinforced bullish sentiment toward the stock.
