Korean Chip ETFs Rip Higher as SK Hynix Dethrones Samsung

South Korea's chipmakers drove the market to fresh highs in the week of 15 to 19 June, led by SK Hynix, whose AI-memory franchise has carried the benchmark KOSPI to an advance of more than 110% in 2026 on top of a 76% gain in 2025. The momentum culminated on Monday 22 June, when SK Hynix rose 5.6% in Seoul to a market value of about 2,080.4 trillion won (roughly $1.35 trillion), overtaking Samsung Electronics (2,066.7 trillion won) to become the country's most valuable listed company. For European investors the move read straight through to Korea trackers, with the six European-listed South Korea ETFs covered here returning a weekly average of 12.48% and individual returns spanning 11.48% to 13.35%.

A Memory Boom and a Changing of the Guard

The first driver is a memory upcycle. Demand for memory tied to AI training and data-centre build-out has rerated the sector worldwide, and SK Hynix has been its clearest beneficiary, with the stock up roughly 350% so far this year against Samsung's 195%. US memory peers moved in sympathy on Monday, Western Digital rising 5.2%, Seagate 4.0%, SanDisk 3.6% and Micron 3.0%. Because Samsung and SK Hynix together account for more than 50% of the KOSPI, that single-sector momentum reads directly into the broad Korea trackers held across this cohort.

The second driver is the leadership change inside the index. SK Hynix overtaking Samsung at the top of the market reweights the bellwether names that dominate these funds, and it helps explain the spread between the FTSE-based and MSCI-based vehicles described below.

The week was not without a cautionary note. South Korea's Financial Supervisory Service issued an investor warning on leveraged products linked to the same chip names, and its governor acknowledged that approval had come too hastily, flagging possible stabilising measures. Retail margin debt had reached a record 60 trillion won (about $39 billion) by the end of May. None of the European UCITS funds in this cohort are leveraged, but the warning frames the volatility behind the headline returns.

The Rally in Context

The longer arc is steep. The KOSPI's gain of more than 110% in 2026, following 76% in 2025, places it among the world's strongest equity markets over the period, and the cohort's 127.50% year-to-date return reflects that run.

The structural overhang has not cleared, however. Despite the bull market, MSCI has still not upgraded South Korea to developed-market status, citing unresolved criteria including the absence of a fully deliverable offshore currency market, with classification decisions due this week. Seoul has signalled it is in no hurry given heightened volatility, even as the government pursues reforms and plans to open the currency market around the clock from the second half of the year. For funds built on these benchmarks, an eventual reclassification would, in time, reshape the index exposure they replicate.

South Korea ETF Performance

Group-level figures are set out in the accompanying table. Fund by fund, the picture was as follows.

Franklin's FTSE tracker did the heavy lifting. The Franklin FTSE Korea UCITS ETF (FLXK) returned 13.35% on the week and 131.38% for the year, the best of the cohort on both measures, and at $4.60bn it is comfortably the largest. It also drew $181.5m of net new money over the week, the bulk of the cohort's weekly intake. Its edge over the MSCI-based peers, clustered near 11.5%, owes much to a different index basket, since FTSE classifies Korea as a developed market and weights constituents differently, shifting exposure towards the leading chip names.

The two iShares MSCI Korea share classes moved in lockstep. The iShares MSCI Korea UCITS ETF USD Dist (IDKO) returned 11.48% on the week at $1.27bn, while the accumulating sibling, the iShares MSCI Korea UCITS ETF USD Acc (CSKR), returned 11.49% at $869m. Neither registered a net weekly flow, though both added assets across the year ($155.6m and $167.0m respectively); the only practical difference between them is the distribution-versus-accumulation treatment.

The euro share class edged the dollar trackers. The Amundi MSCI Korea UCITS ETF Acc (KRW) returned 11.56% on the week at $957m, drawing a $24.3m weekly inflow and $297.3m for the year. Its slight margin over the USD MSCI peers reflects in part the EUR denomination of the share class rather than any difference in the underlying basket. (The ticker coincidentally matches the won's currency code.)

Xtrackers tracked the MSCI pack. The Xtrackers MSCI Korea UCITS ETF 1C (DBX8) returned 11.48% on the week at $492m, with a $7.0m weekly inflow and $230.4m year-to-date.

HSBC's capped fund was the cohort's contrary signal on flows. The HSBC MSCI Korea Capped UCITS ETF (HKOD) returned 11.79% on the week and 124.84% for the year at $459m, yet it carried a net year-to-date outflow of $350.6m, the only fund in the group to lose assets over 2026 even as it rose sharply. Its capping methodology limits single-stock weights, a meaningful constraint in a market where SK Hynix and Samsung dominate.

A New UCITS Memory Play

The same memory theme has produced a fresh European vehicle. Defiance has launched the Defiance Memory UCITS ETF through HANetf's platform, listed on Xetra and Borsa Italiana, with a London Stock Exchange listing expected to follow and a total expense ratio of 0.69%. The fund targets companies across the memory-semiconductor and data-storage value chain, a segment that has so far been largely accessible to European investors only through US-listed products. The supply backdrop is supportive, with Gartner expecting global memory demand to outstrip supply in 2026 and memory and solid-state-drive prices potentially rising as a result. That US-listed route is exemplified by the Roundhill Memory ETF (DRAM), which has grown quickly since its April debut and counts SK Hynix, Samsung and Micron among its largest holdings. DRAM trades only in the United States and has no UCITS or Canadian equivalent, which is the gap the Defiance launch sets out to close for European investors.
