7709.HK is trading 7.2% down as SK Hynix and the broader memory-chip complex face intense profit-taking.

  • SK Hynix fell 9.71% in South Korea, while Samsung dropped 6.13%, amid renewed concerns about elevated AI valuations and the sustainability of hyperscaler spending.
  • Western Digital’s weak forward outlook and a sharp decline in storage shares amplified pressure across memory stocks.
  • The ETF’s 2x leveraged structure magnifies the underlying SK Hynix-related decline.
