Korea FSS Releases Final Guidelines for Short Selling Compliance: Trading Implications

By Sanghyun Park

  • This final guideline formalizes earlier drafts by the FSS. Though not strictly mandatory, its detailed requirements mean it functions as a de facto rule that must be followed closely.
  • The new, stringent requirements are likely to eliminate common stock borrowing practices in Korea, making timely transactions difficult.
  • New trading patterns and market flows may emerge when short selling resumes in April, with increased importance of borrow balance data and potential rise in counter-flow trading.

Trading Considerations for Won Appreciation & Korean ADR Premium Volatility

By Sanghyun Park

  • Increased exchange rate volatility affects the ADR premium, but past patterns show that exchange rate and ADR premium directions may not always align, requiring consideration of specific contextual factors.
  • If the won appreciates below the 1,300s range, overseas institutions may shift to asymmetric selling of underlying shares for foreign exchange profit, as shown by rising ADR premiums.
  • We should watch for peak conditions to capture significant ADR premiums. Trading options include borrowing underlying shares for ADR conversion, even under the current short-selling ban.

I-Scream Media IPO Book Building Results Analysis

By Douglas Kim

  • I-Scream Media reported its IPO book building results. The IPO price has been determined at 32,000 won, which is at the low end of the IPO price range.
  • A total of 561 institutional investors participated in the IPO survey. The final demand ratio was 31.3 to 1.
  • Our valuation analysis suggests an implied price per share of 41,450 won, which represent a 29.5% upside from the IPO price.

Hyosung Siblings’ Cross-Transfers Are Done: The 10%+ Hyosung Corp Stake Block Deal Remains

By Sanghyun Park

  • The Hyosung siblings swapped ₩60B in shares over August 13-14, raising the elder brother’s Hyosung Corp stake to 40.9% and lowering HS Hyosung below 3%.
  • The younger brother must sell additionally at least 11.2% of his 14.2% Hyosung Corp stake. The elder brother may buy, but his cash position and 40% stake limit his need.
  • This block deal will be the first to apply the new pre-disclosure rule. So, we should use it to test how the rule affects price movements for better entry timing.

EQD | KOSPI 200 Rising With Room to Go Higher (This Week Only)

By Nico Rosti

  • After a large sell-off, similar to other major global markets, the KOSPI 200 INDEX last week rebounded and closed strongly up. In this insight we want to evaluate what’s next.
  • According to our pattern models, at the moment the index is not overbought yet, so in theory the index could rise higher, this week.
  • Pay attention when the index reaches the 385 price area, from there the index could start to encounter some resistance.

Lumir IPO Valuation Analysis

By Douglas Kim

  • Base case valuation of Lumir is target price of 18,542 won per share. Given the low upside relative to IPO price range, we have a Negative view of this IPO. 
  • Our net profit estimates in 2025 and 2026 are 38% and 63.3% lower than the company’s estimates.
  • Lumir provides key technologies for satellite systems, including small synthetic aperture radar (SAR) satellite systems and payloads.
