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