Overview
- A roughly $3.2 trillion rotation between Big Tech and semiconductor stocks has left the S&P 500 trading in a narrow range for more than two months.
- Most chip names, excluding Nvidia, plunged in July and erased about $1.7–$1.8 trillion in market value, with memory companies such as Micron, Samsung, and SK Hynix entering bear-market territory.
- The PHLX Semiconductor Index fell about 13% in July and semiconductor ETFs have seen daily trading surge to more than $40 billion, raising volatility and liquidity concerns.
- A handful of mega-cap leaders have absorbed the flows: the Roundhill Magnificent Seven ETF jumped 2.3% in the latest session and is up over 7% for July while Apple reached a record high.
- Big Tech quarterly results are now the likely near-term catalyst that could break the stalemate, and investors will watch memory-price signals and data-center capex guidance for clues on whether the rotation will reverse.
