How could the AI memory bet by Samsung and SK Hynix affect the Nasdaq?

Likely What happens if… A possibility worth considering, not a forecast.

The Nasdaq may face downward pressure as AI memory concerns drive market drops The market drop, driven by concerns over AI data center construction and costly borrowing, has caused significant declines in major memory chip makers like Samsung Electronics and SK Hynix. Because Samsung's stock performance and market activity mutually influence the movement and sentiment of the Nasdaq index, the concentrated selling pressure in the AI memory sector could translate into downward pressure on the Nasdaq. The iShares MSCI South Korea ETF (EWY), which is heavily weighted by Samsung Electronics (22.1%) and SK Hynix (21%), plunged 13.46% on November 6, 2026, reflecting the intensity of these sector-specific concerns.

The facts so far

As reported. Each one links to where it comes from.

  • iShares MSCI South Korea ETF (EWY) fell 13.46% to $131.65 on November 6, 2026.aol.com
  • Samsung Electronics accounted for about 22.1% of net assets in the EWY fund in August 31 holdings.aol.com
  • The PHLX Semiconductor Index dropped 12.25% on November 5, driven by concerns over AI data center construction.aol.com
  • Korea's KOSPI fell 8.52% by 9:03 a.m. local time on November 6, 2026, triggering a 20-minute trading halt.aol.com

Why it matters

The Nasdaq is a barometer for the health of the technology and AI sectors. Since the AI memory bet is central to the current market volatility, any sustained weakness in the semiconductor supply chain, driven by concerns over borrowing costs or political pauses on data center building, directly impacts the valuation of major tech companies listed on the index.

This market reaction highlights the concentrated risk within the AI hardware supply chain. While the Nasdaq is diversified, its heavy weighting toward technology means it is highly sensitive to the performance of key players like Samsung Electronics and SK Hynix, whose stock movements are currently tied to the global demand for advanced memory chips.

What we don't know yet

  • Will the South Korean government activate a stabilization fund or short-selling ban to support the KOSPI?
  • How will the recovery of the KOSPI affect the perception of AI memory demand?

What would change this answer

The KOSPI closes back above 5,383.80 without government interventionThis would suggest that the market is rejecting the negative sentiment, potentially stabilizing the influence of the memory chip stocks on global indices like the Nasdaq.
Nasdaq 100 futures continue to riseThis would indicate that investors are prioritizing broader tech sector growth over the specific, localized concerns regarding AI memory demand in East Asia.
