September Rebalancing of US SMH Semiconductor Index

SK hynix ADR Newly Added with 4.8% Weight

Samsung Asset Management announced on September 21 that the ‘KODEX US Semiconductor’ Exchange-Traded Fund (ETF) has newly included SK hynix ADR, following a regular adjustment of its underlying index.


The inclusion of SK hynix ADR in the KODEX US Semiconductor ETF was the result of the September regular rebalancing of the underlying index, the ‘MVIS US Listed Semiconductor 25 Index,’ which the ETF tracks. SK hynix ADR, which listed on the US Nasdaq market on July 10, 2026, was included in this major US semiconductor index less than two months after its debut. Its weighting in the index is approximately 4.8%.

The US SMH Semiconductor Index tracked by this ETF is also the index tracked by the largest US semiconductor ETF, the VanEck Semiconductor ETF (SMH). In this regular rebalancing, SMH has also included SK hynix ADR in the same manner. SMH has approximately $70 billion (about 97 trillion won) in net assets, making it the largest US-listed semiconductor ETF by net asset size.


KODEX US Semiconductor is an ETF listed in Korea that follows the same US SMH Semiconductor Index as SMH. Domestic investors can thus invest in the same portfolio as the largest US semiconductor ETF, but in Korean won. The ETF invests in 25 key global semiconductor companies listed in the US, such as Nvidia, TSMC, Broadcom, ASML, and Micron. With this rebalancing, SK hynix ADR has also been added to the portfolio.


SK hynix is leading the memory semiconductor market, particularly represented by high-bandwidth memory (HBM), which is drawing significant attention in the AI era. With the recent inclusion, KODEX US Semiconductor now includes not only computational semiconductors such as GPUs and ASICs, foundries, and semiconductor equipment, but also AI memory centered on HBM. This demonstrates the index methodology’s strength in quickly reflecting changes in the global semiconductor industry.



Donghoon Han, a manager at Samsung Asset Management, stated, “The semiconductor industry underpinning AI is undergoing various changes amid a major growth trend. The recent inclusion of SK hynix ADR is further proof that KODEX US Semiconductor is a product that quickly incorporates the latest trends and industry representation.”
