Hynix ADR premium at 51%, global funds are pouring into Korean ETFs.

```

The huge price gap between SK Hynix American Depositary Receipts (ADR) and Korean local shares is fueling a proxy trading frenzy around Korean ETFs.

BlackRock's $23 billion iShares MSCI Korea ETF (ticker: EWY) attracted over $1.1 billion in a single day on Wednesday, following a record net inflow of $814 million the previous day. Since the fund allocates about a quarter of its holdings to SK Hynix shares listed in Korea, investors see it as the most convenient channel for indirectly gaining exposure to the chip giant while bypassing the high-premium ADR.

As of Thursday afternoon New York time, the premium of SK Hynix ADR over local Korean shares was about 27%, after soaring to a historic peak of 51% the previous day. This spread is unlikely to narrow in the short term—ADR issuance and cancellation channels will only reopen later in the month, and there remains uncertainty about the subsequent conversion capacity and regulatory approval.

Since the start of the year, EWY has absorbed more than $6.3 billion in inflows, and the fund's asset size has soared over 180% from the beginning of the year.

High ADR Premiums, Arbitrage Mechanism Blocked

The pricing gap between SK Hynix ADR and local shares stems from the temporary breakdown of the normal arbitrage mechanism.

Under usual circumstances, the price difference between ADRs and corresponding local shares would be quickly eliminated through conversion operations such as ADR issuance or cancellation. However, both issuance and cancellation are currently closed, and are expected to reopen later this month. Even when the channels reopen, how much conversion capacity will be available and whether further regulatory approval will be needed remain unclear.

This structural constraint keeps the premium persistent. According to Bloomberg data, Taiwan Semiconductor’s ADR has averaged around a 20% premium over the past year due to only partial convertibility of local shares. SK Hynix is facing a similar situation, albeit with a more extreme premium.

EWY Becomes the Optimal Proxy Tool

Faced with sky-high ADR premiums, some investors are turning to EWY to gain exposure to SK Hynix. EWY allocates about a quarter of its assets to SK Hynix shares listed in Korea, while sidestepping challenges such as off-market trading and currency conversion involved with directly holding Korean stocks.

“Investors are using EWY as a tool to access Korean-listed stocks,” said Dave Lutz, equity sales trader and macro strategist at Jonestrading Institutional Services LLC.

Strategas Securities Chief ETF Strategist Todd Sohn added, “ETFs are essentially proxy trading tools, and are extremely efficient at gaining exposure to emerging market or developed market themes.”

AI Chip Boom Drives Inflows

The broader context is that Korean memory chip stocks have become one of the hottest AI trading targets this year. After SK Hynix completed its US listing, capital continued to flow in despite periods of market volatility. In Korea’s domestic market, retail trading enthusiasm for single-stock ETFs linked to SK Hynix and Samsung Electronics is running high, prompting regulators to temporarily halt new launches of such single-stock ETFs.

“Some inflows may be from short-covering,” said Tom Graff, Chief Investment Officer at Baltimore-based asset manager Facet. “Demand remains remarkably strong, but whether it is sustainable is unknown. However, most short positions get stopped quickly in this market, which makes sense.”

Since the start of the year, EWY’s assets have swelled from less than $800 million to $23 billion—an increase of more than 180%—reflecting strong global pursuit of Korean tech assets.
