POSCO: Reviewing a Potential M&A of HMM
- The biggest potential M&A event right now in Korea is the potential acquisition of HMM Co., Ltd. (011200 KS) by POSCO Holdings (005490 KS).
- Overall, we believe there is a higher probability of POSCO backing out of this potential acquisition of HMM, rather than POSCO completing this M&A deal.
- Although POSCO claims that it spends about 3 trillion won annually on logistics, the actual synergies among these three businesses (steel, rechargeable battery, and logistics) remain murky.
Taiwan Top 50 ETF Rebalance: Another Inclusion for Caliway Biopharma & King Slide
- Caliway Biopharmaceuticals (6919 TT) and King Slide Works (2059 TT) replace Taiwan Cement (1101 TT) and Pharmaessentia Corp (6446 TT) in the Yuanta/P-Shares Taiwan Top 50 ETF in September.
- Caliway Biopharmaceuticals (6919 TT) and King Slide Works (2059 TT) were added to a global index in August and that resulted in a large percentage of float being bought.
- Caliway Biopharmaceuticals (6919 TT) will be added to another global index in September and that will further reduce the real float of the stock.
KRX September Sector Index Review Finalized: Passive Impact Read
- KRX dropped its September sector rejig post-close: only Semis (₩0.96T), Autos (₩0.51T), and Healthcare (₩0.31T) matter. Lineup below.
- AUM-Wise, Semis was key. September TMI reshuffle saw light additions, heavy deletions; otherwise, results largely matched earlier forecasts.
- TMI reshuffle flew under the radar with little pre-positioning; ETF rebalances next Thursday could trigger notable price moves — consider long/short baskets on high-impact names.
S&P/ASX Index Rebalance (Sep 2025): New Methodology & The Many Changes
- There is 1 change for the S&P/ASX50 Index, 3 changes for the S&P/ASX100 Index, 9 changes for the S&P/ASX200 (AS51 INDEX) and 17 adds/ 12 deletes for the S&P/ASX300 Index.
- Some of the index changes will also have same way flows from trackers of other global and sector indices on the same day.
- The adds have outperformed the deletes across all indices and performance has been especially strong for the S&P/ASX100 Index and S&P/ASX300 Index changes.
Regarding the Six KRX Sector Names that Ran Ahead of Friday’s Official Review Drop
- Six names stood out with simultaneous volume spikes and sharp pops last Friday; all Semis and Autos additions with big passive impact, while all others showed no tape action.
- Results likely leaked early, prompting front-running on Semis and Autos adds—high passive impact names—causing Friday’s sharp volume and price spikes.
- Early movers are mostly priced in; Thursday momentum plays still work, but Monday–Thursday morning requires caution. Focus on volume-driven flows before loading positions, long-short basket viable for other passive-impact names.
Chery Automobile IPO: The Bull Case
- Chery Automobile (CH3456 CH), a Chinese automobile manufacturer, has secured HKEx listing approval for a US$1.5-2.0 billion IPO.
- Chery is the second largest Chinese domestic brand passenger vehicle company, and the 11th largest passenger vehicle company globally.
- The bull case rests on market share gains, encouraging NEV segmental performance, good margin profile and cash generation.
