Korean retail investors shifted focus from Magnificent 7 tech giants to semiconductor and infrastructure stocks during the week of June 26-July 2, with Micron topping net purchase rankings at $271.33 million. The investment rotation reflects the emergence of 'Parabolic 7' (P7) - Micron, SanDisk, AMD, Broadcom, Marvell Technology, Intel, and Dell Technologies - which have outperformed traditional big tech as AI datacenter spending expands beyond initial software beneficiaries. The P7 concept, coined by FedWatchAdvisors CIO Ben Emmons and popularized via Bloomberg, describes companies exhibiting parabolic stock price curves driven by direct AI infrastructure demand.
P7 Market Capitalization Reaches 8% of S&P 500
P7 companies' combined market capitalization grew to approximately 8% of the S&P 500 and 11% of Nasdaq as of early last month, according to market data. The seven-company group comprises memory chipmaker Micron, storage specialist SanDisk, processor manufacturers AMD and Intel, networking chip provider Marvell Technology, custom chip designer Broadcom, and server vendor Dell Technologies. Samsung Securities researcher Kim Jung-han stated that while big tech companies spend capital on AI infrastructure, semiconductor supply chain companies receive the revenue flows from datacenter investment by major cloud providers.
Korean Investors Net Purchase Micron $271.33M During June 26-July 2
Korean investors purchased a net $271.33 million in Micron stock during the week of June 26-July 2, making it the top overseas stock purchase, according to Korea Securities Depository data released July 5.

SanDisk Surges 635.1% Year-to-Date Through July 3
P7 stocks posted substantial gains from the beginning of the year through July 3. SanDisk rose 635.1%, while Micron, Intel, and Dell each climbed over 200%. In contrast, M7 stocks underperformed the S&P 500 by 13 percentage points this year and declined an average of approximately 10% in June alone. Hana Securities reported that year-to-date, M7 stocks returned approximately 2% compared to 14% for non-M7 S&P 500 constituents. The 2026 earnings growth forecast gap between M7 (44%) and non-M7 (39%) companies has narrowed.
Micron, ranked third globally in memory semiconductors, has posted consecutive quarterly record results driven by high-bandwidth memory (HBM) supply for AI servers. SanDisk has established a leading position in NAND flash for enterprise solid-state drives. Intel is pursuing a turnaround through next-generation semiconductor processes and advanced packaging technology. Dell benefits from expanded server shipments incorporating Nvidia AI chips. Marvell competes in AI datacenter networking semiconductors, while AMD is positioned as a viable Nvidia alternative. Broadcom has gained valuation through custom AI chip (ASIC) design capabilities.
Broadcom Stock Drops 13% Day After Earnings Report
Broadcom shares fell approximately 13% the day following its earnings announcement on June 3, despite revenue growing 48% year-over-year and exceeding market expectations. The decline occurred after the company provided third-quarter AI semiconductor revenue guidance below analyst projections. FedWatchAdvisors CIO Emmons noted that during the past five years, while broader index drawdowns remained around 25%, stocks with similar rapid appreciation patterns experienced declines exceeding 45%.

Yorkville America, operator of the TruthSocial ETF series, submitted an application on June 16 to launch a 'Mango Plus' ETF incorporating P7 stocks, according to Reuters. The filing reflects growing interest in products targeting the semiconductor and infrastructure investment theme. Market observers are monitoring whether P7 momentum represents a temporary sector rotation or marks the emergence of new market leadership replacing M7 dominance.
