SanDisk Surges 635% YTD as P7 Semiconductor Stocks Rally Over M7, Micron Sees $271M Korean Investor Inflows in One Week

According to the Korean Securities Depository, Parabolic-7 (P7) semiconductor stocks including Micron, SanDisk, AMD, Broadcom, Marvell, Intel, and Dell Technologies surged in late June through early July, outpacing the struggling Magnificent-7 tech giants. SanDisk rallied 635% since the start of the year, while Micron, Intel, and Dell each posted gains exceeding 200%. From June 26 through July 2, Micron attracted $271.3 million in net purchases from Korean investors, ranking first among foreign stocks, with SanDisk drawing additional 2x leveraged bets.

Wedbush Securities analyst Dan Ives noted on CNBC that AI monetization is expanding beyond large cloud companies into semiconductor, infrastructure, and equipment suppliers, as data center capital investments flow through the semiconductor value chain. The P7 index reached approximately 8% of S&P 500 market capitalization and 11% of Nasdaq market cap as of early June, compared to the M7's 2% YTD return versus 14% gains for non-M7 stocks.
