Hynix Could Follow Samsung With Key Disclosure Ahead of Oct 7 MTD Reply

By Sanghyun Park

  • For memory swing traders, October 7’s MTD reply is the key catalyst, with Hynix potentially front running it by disclosing HBM customer commitments and 2027 capacity allocation.
  • Samsung’s HBM capacity messaging strengthens the supply trade off case, while Hynix could go further with customer commitments and allocation data to support an AI driven capacity reallocation narrative.
  • For Hynix, hard 2027 HBM capacity numbers or incremental customer commitments would matter far more than another generic capacity update, potentially driving estimates and near term share price volatility higher.

Cheil Worldwide – Cancellation of 13.9% of Outstanding Shares

By Douglas Kim

  • On 30 September, Cheil Worldwide (030000 KS) announced that it is cancelling its entire treasury shares, representing 12% of outstanding shares. 
  • Cheil Worldwide also plans to buy back an additional 40 billion won worth of shares on the open market between October 1 and December 30, representing 1.9% of outstanding shares.
  • The bigger concerns are the company’s relatively flat growth in sales and profits which has partly been due to the negative impact of the greater use of generative AI services.

Korean Holdcos Vs Opcos Gap Trading Opportunities in 4Q 2026

By Douglas Kim

  • In this insight, I highlight the recent pricing gap divergences of the major Korean holdcos and opcos which could provide trading opportunities in 4Q 2026.
  • I provide five holdco/opco pairs that have experienced noticeable divergence in the past three months and closing of their gaps could occur in the next several weeks.
  • Of the 38 pairs, six of them are near or more than 2 standard deviations (in terms of their changing share price movements in the past three months).
