Potential Inclusion of SK Hynix ADR in NASDAQ 100 Index in December 2026

By Douglas Kim

  • In this insight, I discuss the impact of the potential inclusion of SK Hynix (SKHY US) ADR in the NASDAQ 100 rebalance in December 2026. 
  • There are 17 other companies in the NASDAQ 100 Index which have lower market cap than SK Hynix’s ADR capitalization. 
  • I believe there is a high probability (80-90%+) of SK Hynix (SKHY US) ADR inclusion in the NASDAQ 100 Index in December 2026.

SK Hynix (000660 KS): Volatility Falls to 55% as Leveraged ETF Activity Fades

By Gaudenz Schneider

  • SK hynix (000660 KS) gained 11.2% in September MTD and its 2x Leveraged Index rose 20.9%, but combined AUM increased only 10% as redemptions offset performance.
  • Units outstanding fell across all seven long leveraged ETFs. In contrast, units in the inverse product more than doubled and its market capitalisation rose 56%, despite negative performance.
  • Annualised 21-day volatility more than halved from its late-July peak of 179% to 55%. The decline coincided with the collapse in ETF trading activity and fund flows following regulatory changes.
