What Is EWY and Why Two Chip Stocks Are 55 Percent of Korea's Biggest ETF

EWY is the iShares MSCI South Korea ETF, and at 31 May 2026 it held 54.73% of its net assets in exactly two companies. SK hynix was 30.85% and Samsung Electronics 23.88%, against net assets of $24.14 billion. It trades on NYSE Arca and it trades on Phemex as a 10x perpetual.

Phemex lists eight South Korea contracts and four of them reference SK hynix at different scales. The census matters because EWY already carries that company at 30.85%, so a reader holding the fund owns the same name twice over. Over 23 June to 11 September 2026 the fund fell 3.37% on perpetual closes while every chip proxy on the board fell harder.

What Is EWY and What Does the Fund Actually Own?

EWY is a plain 1x country fund that tracks the MSCI Korea 25/50 Index, and BlackRock's iShares unit runs it on NYSE Arca. The summary prospectus dated 30 December 2025 names the ticker and the exchange in its opening line. There's no daily reset and no leverage inside the wrapper.

The portfolio report filed on 27 July 2026 lists 85 positions at 31 May 2026 against net assets of $24,140,622,304. SK hynix accounts for 4,783,859 shares worth $7,448,503,648, which is 30.85% of the fund. Samsung Electronics accounts for 27,473,006 common shares worth $5,763,661,630, or 23.88%. A separate line holds 121,532 Samsung preferred shares at 0.07%. Add the two chip names and you reach 54.73% of net assets in two companies, or 54.80% counting the preferred.

Everything else is small.

SK Square is 3.08% and Samsung Electro-Mechanics is 3.42%, and the largest non-Korean position is a BlackRock cash fund at 4.88% holding securities-lending collateral. Good risk management in derivatives trading starts with knowing what you hold, and the EWY ETF holdings are two chip names with a Korean index wrapped around them.

Why the 25 Percent Cap Does Not Cap the Fund

The index caps and the fund drifts. The prospectus says the underlying index "uses a capping methodology that limits the weight of any single 'group entity' ... to a maximum of 25% of the Underlying Index weight, and the sum of all group entities with a weight above 5% to an aggregate of 50%". Two positions in this fund exceed 5% of net assets and they add to 54.73%.

Those two figures measure different objects and a reader who merges them will conclude the fund broke a rule it never signed. The 25% number is an index-level limit applied to index weight, and MSCI enforces it when the index rebalances. The 30.85% is a fund-level weight measured against net assets on one dated report. Between rebalance dates a holding that doubles takes its weight with it.

The cost of owning the structure is fixed and published. The EWY expense ratio runs at 0.59% of assets a year, and the prospectus prices that at $60 over one year and $738 over ten years on a $10,000 position. Portfolio turnover ran 49% in the most recent fiscal year.

Eight Korea Contracts on Phemex and Four of Them Are SK hynix

Four of the eight reference one company. SKHYNIX-USDT and SKHY-USDT are two live contracts on SK hynix at two scales, 1,369.50 against 190.26 at the Friday 11 September close, a factor of 7.198. The cheaper contract turned over 5,724.99 units that session against 550.11 on the expensive one, so the small-denomination version carried 10.4 times the volume.

A trader who buys EWY futures already owns 30.85% SK hynix before adding a single chip contract. Stack SKUU-USDT on top and the exposure compounds twice over, because that fund is itself a 2x daily product on the same name. The board gives you five separate ways to be long one Korean memory maker and only one of them announces itself as a country fund.

Why the Concentration Claim Is Structural and Not Directional

The easy version of this story says a fund that is half semiconductors has to move like semiconductors. The tape says otherwise.

A fund carrying 54.73% in two chip names outperformed every chip proxy on the board across the same eleven weeks. So the concentration claim here is structural and it is not directional. EWY tells you precisely what you own, and it tells you nothing about which way the thing goes.

The window opens on a loaded date and that deserves saying out loud. EWY closed 23 June down 9.54% from the session before, on the Korean chip session our desk covered in the 23 June crash that hit Samsung and SK hynix. Measured from the 18 June close of 219.11 instead, EWY is down 13.61% to 11 September. The 23 June start was chosen because it is the first bar every contract in the table shares, and it flatters the fund a little.

What the EWY Perpetual's 179 Bars Say and What They Cannot

EWY-USDT has 179 complete daily bars, because it listed on 17 March 2026 at 10:00 UTC and its first bar carries that date. No 52-week window exists on this contract, so anyone quoting one on EWY futures is quoting something else.

Point to point, the perpetual closed 134.77 on 17 March and 189.30 on Friday 11 September, a gain of 40.46%. The low-to-high span across the same 179 bars is 94.52%, from 113.38 intraday on 31 March to 220.55 intraday on 18 June. Those two numbers measure two different things. The span measures the widest distance the contract travelled, and the point-to-point figure measures what a holder from the first bar actually kept.

The fund itself has the longer record. The Yahoo Finance equity feed covers the 365-session window ending Friday 11 September 2026 on a closing basis. It returns 251 NYSE Arca sessions and a move from 78.66 on 12 September 2025 to 188.72 on 11 September 2026, a gain of 139.92%. No split and no re-basing sits in either series, which is the first thing to check before any long-window percentage on a TradFi contract. The venue history and the fund history answer different questions, and how perpetual and quarterly futures settle explains why the shorter one exists at all.

Why EWY Prints Bars on Days NYSE Arca Is Shut

Fifty-five of the contract's 179 bars landed on a day with no US session, and those bars carried 15.85% of total volume and 10.12% of all open-to-close movement. The perpetual never closes and the fund it references does.

Labor Day is the clean example. EWY closed 187.53 on Friday 4 September and 190.83 on Monday 7 September, a gain of 1.76% across three consecutive non-sessions, then gave back 0.755% when the real open arrived on Tuesday 8 September. Labor Day checks out two independent ways. The statute sets the holiday as the first Monday in September and 7 September 2026 is a Monday, and the NYSE Arca tape carries no session at all that day.

Funding is the other half of the weekend question, and on this contract it does nothing.

Method: I pulled each listed contract's own 8-hour funding series and counted the non-zero prints. Across 45 settlements from 28 August 00:00 UTC to 11 September 16:00 UTC, EWY printed exactly zero every time. So did 47 of its 61 fellow TradFi perpetuals, while Bitcoin printed a non-zero rate on all 45. If you've never priced that gap, how funding rates work on crypto futures is the place to start.

Zero funding hasn't cost the contract its tracking. Across the ten NYSE Arca sessions from 28 August to 11 September the mean absolute gap between the perpetual close and the fund close ran 0.249%, and on the anchor session the perpetual printed 0.31% above. That is the work of market makers and market takers meeting on a screen that never shuts.

What the 15-16 September FOMC Changes for EWY Holders

The August 2026 CPI landed at 12:30 UTC on Friday 11 September, the anchor session itself, at +0.4% month over month seasonally adjusted and +3.4% year over year before seasonal adjustment. The Federal Reserve's rate-setting committee meets on 15 and 16 September and publishes a Summary of Economic Projections alongside the decision. Those are the scheduled facts and the outcome is not one of them.

What to watch: EWY-USDT carries 10x maximum leverage and an 8-hour funding clock into a projection release that lands two days after a weekend gap. A Korean fund whose weekend bars already move 10.12% of its total travel meets a US macro event on a Tuesday and Wednesday, and the gap risk runs in both directions.

Demand for the South Korea ETF isn't the question either way. The fund traded a median 13,177,900 shares a session across the 251 sessions to 11 September, then 11,830,500 on the anchor, closing up 3.25%.

Frequently Asked Questions

Is EWY a leveraged ETF?

No. It is a plain 1x country fund with no daily reset. The leveraged Korea products are separate contracts, and Phemex caps EWY-USDT at 100,000 contracts of open interest with a 0.01 tick size.

How concentrated is the rest of the book?

Only 13 of the 85 positions exceed 1% of net assets, and two of those exceed 5%. Eighty-three of the 85 lines carry a Korean country code and two carry a US one.

Does EWY hold Samsung's preferred shares as well?

Yes, on a separate line. The report lists 121,532 shares under ISIN KR7005931001 at 0.07% of net assets, alongside the 27,473,006 common shares under KR7005930003.

What does the EWY perpetual price against?

An index Phemex publishes as .EWYUSDT, with the mark price carried on .MEWYUSDT. The contract settles in USDT and each unit references one share.

Bottom Line

EWY is sold as South Korea and it prices as SK hynix with an index wrapped around it. The document that proves it is public and it's free, the weight was 30.85% on 31 May 2026, and the fund still beat every chip proxy we measured over the eleven weeks that followed. Own the concentration on purpose, or hedge it against one of the four SK hynix contracts already listed, and size either one while the 15-16 September projection release is still ahead of you.
