Stealthy Long-Short Flow Playing Out Via Local KOSPI 200 Covered Call ETFs

By Sanghyun Park

  • Covered call ETFs ramped up KOSPI 200 weekly call selling, pushing premiums unusually low despite modest overall volume—likely a key driver behind the premium compression.
  • KOSPI 100 outperformed KOSPI 200 small-mid caps by 3.7%p last month, probably boosted by call-selling ETFs’ delta-hedge buying concentrated in large caps.
  • Watch for hedge buy flows ramping up before big events. Timing short-term longs in large caps and shorts in smaller KOSPI 200 names around these windows can yield solid alpha.

Samsung Electronics (005930 KS) Tactical Outlook : New Rally After Large Pullback?

By Nico Rosti

  • Samsung Electronics (005930 KS) has been rallying for quite a while in the last few weeks, and we have been bullish on the stock since the start of the year. 
  • At the moment the stock is very overbought according to our model, we see potential for a pullback, possibly something larger than a buy the dip.
  • A 2 or even a 3 weeks correction should not be ruled out at this stage, 64700 is the limit support zone we are looking at, the short profit target.

KT Corp: Excellent 2Q 2025 Earnings Driven by Market Share Gain and Improving AI/Cloud Businesses

By Douglas Kim

  • The most important reason for KT’s excellent results in 2Q 2025 was due to the major hacking incident at SK Telecom in May 2025.
  • The company’s growing AI business and successful real estate sales also contributed to the company’s improving results in 2Q 2025. 
  • KT is likely to benefit from higher profits and returns on capital in the next couple of years as the penetration of 5G service surpasses more than 80%.

LS Corp: Treasury Share Cancellation of 171 Billion Won

By Douglas Kim

  • On 12 August, LS Corp (006260 KS) announced that it will cancel 1 million treasury shares (171 billion won), representing 3.1% of its outstanding shares.
  • This is significant, especially because the company has not cancelled any shares in the past five years. This move signals the company’s willingness to provide greater returns to its shareholders.
  • LS plans to increase its dividend by at least 5% annually, to reach dividend payout of at least 30% by 2030.
