Key points
- SK Hynix trades on Nasdaq as SKHY. Any US broker takes the order, no special access needed.
- Two dead symbols to avoid: SKHYV, retired July 13, and HXSCL, the old over-the-counter line.
- Six leveraged funds track it. From July 14 to August 4 the stock fell 20.4% and the 2x funds fell about 44%, not 40.8%.
- 10 SKHY equal 1 Seoul share, and SKHY has run about 29% above the Seoul price.
SK Hynix listed on the Nasdaq under the ticker SKHY on July 10, 2026, and you buy it the same way you buy anything else on a US exchange. Search the ticker, place the order, done. What follows is the part that actually trips people up: two retired symbols still floating around in search results, which stocks are the real ways into this trade, and the six leveraged tickers that now track it.
The ticker is SKHY, and every US broker has it
SKHY trades like Apple or Microsoft. Robinhood, Fidelity, Schwab, E*Trade, Vanguard, Merrill and Interactive Brokers all support it. There is no international trading permission to enable, no foreign exchange account, and no workaround. Type SKHY, place a market or limit order, and you own it. It works the same inside an IRA.
If your app cannot find it, you are almost certainly typing a symbol that is dead. There are two of those. SKHYV was the when-issued ticker, used on debut day only while the deal finished settling, and it converted to SKHY on July 13, 2026. HXSCL was an unsponsored over-the-counter ADR, the only way most Americans could touch SK Hynix before this listing, and it stopped trading once the sponsored Nasdaq listing went live. That is what normally happens to an unsponsored line when a company lists properly.
SKHY is not a thin foreign listing, either. It has been turning over roughly 40 million shares a day and has listed options running out to December 2028.
Which stocks actually give you this trade
There are three answers, and one of them you cannot have.
SKHY is the direct one. Each American depositary share represents one tenth of one SK Hynix common share, so 10 SKHY equal one share of the Seoul-listed line, ticker 000660. Same company, priced in dollars. One wrinkle: the price is set in dollars but tracks a stock priced in Korean won, so the ADR moves on two things at once, how the business is doing and where the won sits against the dollar.
Micron (MU) is the closest US-listed alternative, and the only other pure play on the high bandwidth memory that goes into Nvidia's AI accelerators. The two companies are close to the same size, with SK Hynix's trailing revenue and net income each within about 1% of Micron's. If you want this trade as a plain American common stock with no ADR involved, Micron is it. We put the two side by side here, and if the memory story is new to you, start with what HBM actually is.
Samsung Electronics is the one that is off the table. It is the third of the big three memory makers and has no US listing at all, sponsored or otherwise. Korea-focused ETFs hold it, but no ticker gets you Samsung on its own.
Before you place any of these orders, there is one number worth checking. SKHY has traded at a persistent premium to the Seoul shares since day one, and that premium is real money on top of the business. The math takes ten seconds: take the Seoul price in won, divide by the won/dollar rate, then divide by 10. On August 5, SK Hynix closed at 1,668,000 won in Seoul, or roughly $117 per share of SKHY. SKHY closed at $150.99. You were paying about 29% over the Korean price. That spread hit 51% on July 14, compressed to 22% by July 28, then blew back out to 33% on July 29 when Seoul dropped hard and the US line did not follow. We covered why it exists. If it ever went to zero with Seoul unchanged, SKHY would be worth about $117.
The leveraged tickers, and why the math works against you
Six leveraged funds now track SKHY, and they arrived within days of the listing. Five give you 2x the daily move and one gives you 2x the inverse.
| Ticker | Daily target | July 14 to August 4 |
|---|---|---|
| SKHY | the stock itself | -20.4% |
| SKHU | 2x long | -44.4% |
| SKUU | 2x long | -43.9% |
| SKHX | 2x long | -43.9% |
| SK | 2x long | -43.7% |
| SKHL | 2x long | launched July 15 |
| SKDD | 2x short | +11.8% |
Look at what that table is telling you. The stock fell 20.4% over those three weeks. Two times 20.4% is 40.8%, so that is what a 2x fund "should" have lost. Every one of them lost closer to 44%. Those extra three points did not go to fees. They were burned by the way the funds work.
The word doing the damage is daily. These funds promise 2x the move over a single session, and then they reset. Every afternoon the fund rebalances so that tomorrow it again has exactly twice the exposure, based on whatever it is worth that evening. That works fine in a straight line. It does not work in a chop, because after a down day the fund rebalances to a smaller base, so the next up day is applied to less money. Losses shrink the base faster than gains rebuild it.
SKHY spent those three weeks doing exactly the thing that punishes this structure. It went from $193.92 down to $124.80, then snapped back 21% in five sessions. A stock that grinds steadily in one direction can leave a 2x fund ahead of the naive math. A stock that thrashes, which is what this one has done since the day it listed, grinds it down.
The short fund is the clearest warning in the whole table. Anyone who bought SKDD on July 14 was right. The stock fell 20.4% over the next three weeks, exactly the call they made. Twice that is a 40.8% gain. They made 11.8%. Being correct about direction returned them barely a quarter of what the leverage advertised, because the path there was violent enough to eat the rest.
None of this makes these funds broken. They do precisely what their prospectuses say, which is deliver 2x for one day. It makes them the wrong instrument for an opinion measured in weeks or months, and SKHY, which has already traveled from $124.80 to $194.80 inside its first month, is close to a worst case for holding one. If you want leverage on a view that lasts longer than a session, the listed options are a more honest way to buy it, because at least the cost is quoted to you up front as a premium instead of bleeding out of the position a few basis points at a time.
The bottom line
Buy SKHY through your normal brokerage account like any other Nasdaq stock. Ignore SKHYV and HXSCL, which are both dead. Check the premium against Seoul first, because 29% is not a rounding error. Leave the 2x tickers alone unless you are trading them inside a single session and know exactly why.
And size it knowing what this stock is. The offering priced at $149 on July 9 and raised $26.51 billion, the largest share sale by a foreign company in US history, ahead of Alibaba's $21.8 billion NYSE debut in 2014. It closed its first session at $168.01 and ran to $194.80 by July 14. Then second quarter results on July 29 came in light on both lines, revenue of 79.32 trillion won against 84.06 trillion expected and operating profit of 60.54 trillion against 64.09 trillion, each about 5.5% short, with the company saying some HBM4 shipments had slipped into the second half. The stock bottomed at $124.80 that day before taking back 21% in five sessions to close at $150.99 on August 5. Six firms opened coverage in the first week of August, all at buy or the equivalent, with targets from $204 to $330. Those are first opinions on a stock with a four-week trading history.
