description: "Found many newbies asking questions in the comments 😂, let's briefly talk about SK Hynix's ADR here.The US-listed SK Hynix is like a clone of the Korean-listed SK Hynix. The ADR raised $26.5 billion, accounting for only 2.5% of the Korean stock's trillion-dollar total market cap. Do you expect the 2.5% size of the US stock to move the 97.5% behemoth of the Korean market?So even if US Hynix goes crazy today, it won't have much impact on the Korean main stock. Assuming market sentiment is bad next Monday, it's possible the Korean stock could fall instead of rise, and foreign capital selling Korea to buy the US is also negative.Secondly, it has little impact on $Roundhill Memory ETF(DRAM.US) and $XL2CSOPHYNIX(07709.HK). Let alone that Hynix is only one of the top ten holdings of DRAM, it went up but other holdings are falling, and both DRAM and the Hong Kong 2x ETF track the Korean Hynix, not the US ADR.Furthermore, today is the first day of SK Hynix's US listing, and it surged over ten points due to excited market sentiment. This is actually "sentiment premium," not the real stock price. Starting next week, the US ADR will track the price fluctuations of the Korean Hynix and gradually synchronize (I guess listing on Friday night is also to avoid excessive impact on the Korean stock, leaving the weekend to digest sentiment).However, since the US ADR only accounts for 2.5% ($25.6 billion) of the Korean Hynix's total market cap, and the conversion from Korean stock to ADR is one-way locked, the ADR share won't increase significantly until at least after 2028. Due to scarcity, high liquidity, and currency loss factors, the US Hynix will maintain a premium long-term.Referencing TSMC's ADR, the US-listed TSMC has a long-term premium of 10-15% over the Taiwan stock. TSMC is a unique, weak-cycle monopoly enterprise, so its premium being higher than that of the strong-cycle, replaceable Hynix is normal. I think a long-term premium of around 5-10% for US Hynix is reasonable.Today's Korean Hynix closing price, after a 1-for-10 split converted to USD, is about $146.5. The US stock is currently $173. The extra is all premium, about 18%, making it hard to buy now.The Korean Hynix's all-time high is $198. I plan to wait for a 35% pullback - minus 10% premium = a 25% pullback, around $150, before buying. Mainly because I've almost missed all the memory market trends in the past half year, missing another one isn't a pity. Even if I chase highs, I want a safety cushion. This is for reference only.Report complete.

- **晴儿2025 · 2026-07-11T00:28:59.000Z**: Well said
- **旺旺勇闯美股 · 2026-07-10T23:47:13.000Z · 👍 1**: Great article and analysis, much better than those that pile on professional jargon and don't speak in plain language. I'm also waiting for 150.
- **个狗 · 2026-07-10T22:40:11.000Z**: Boss, I'd like to ask: will the listing of mainland China's ChangXin have an impact on DRAM?
  - **退场** (2026-07-11T04:35:54.000Z): Even less of an impact, he's not even in the dram holdings.. but his intense speculation might stir up the "Haixingmei" sentiment.
- **拿不住就去进厂 · 2026-07-10T22:26:24.000Z · 👍 1**: If you're not prepared to hold a stock for the long term, I think you shouldn't buy into it. Short-term speculation is like getting hit from both sides.
- **东南西北的东Dong · 2026-07-10T19:22:59.000Z · 👍 1**: A very fair and easy-to-understand article, great.
- **diamond man · 2026-07-10T18:45:58.000Z · 👍 2**: The analysis is good, but it feels hard to go back below 150 in the short term, right?
  - **退场** (2026-07-10T18:47:47.000Z): If it had been listed a few days ago when storage stocks plummeted, it would have been below 150. It's just that storage has recovered these days🌚
  - **diamond man** (2026-07-10T18:57:00.000Z): My understanding is (though it's debatable) that the big drop in storage over the past week was to suppress the price of these ADRs.
  - **退场** (2026-07-10T19:05:50.000Z): There are reasons for each side, so I won't explain. I mean there's still a chance for 150.
- **让韭菜再次伟大 · 2026-07-10T18:39:01.000Z · 👍 1**: Thanks, boss. Almost rushed in.
- **早日财富自由啊 · 2026-07-10T18:23:37.000Z**: Is it not possible to convert Korean stocks into ADRs? I seem to have seen somewhere before that it can be done to balance the price difference between the two sides.
  - **退场** (2026-07-10T18:26:40.000Z): Not possible for now. The Korean Securities and Futures Commission has restrictions. It takes time to enact and amend laws for these matters. Additionally, SK hynix's major shareholder must keep 20% o
- **港股摸金小黑手 · 2026-07-10T18:18:00.000Z · 👍 1**: Quite fair, I also think it's an emotional price for now, waiting.
- **kikoy · 2026-07-10T18:17:25.000Z · 👍 2**: If I had seen it earlier, I wouldn't have been trapped.
- **阿菜 · 2026-07-10T18:16:53.000Z · 👍 2**: What's your position size in Oracle, buddy?
  - **退场** (2026-07-10T18:31:15.000Z): Almost half position, trapped and numb lol
  - **豆豆丶** (2026-07-10T18:33:17.000Z): Can Oracle be averaged down? (´o̴̶̷̤ㅂ o̴̶̷̤`) Averaged down twice, now the cost is 180.
  - **退场** (2026-07-10T18:38:07.000Z): I averaged down with 30 shares at 140, my actual cost is 150.8. I wanted to wait for 135 to average down again, but if there's no chance, then forget it. I want to keep some ammunition for speculative
- **禁止賭博！ · 2026-07-10T18:13:45.000Z · 👍 2**: Why can't I see your rate of return?
  - **退场** (2026-07-10T18:30:38.000Z): I don't use Longbridge, and my recent return has been cut in half🤪
- **rmk · 2026-07-10T18:10:36.000Z · 👍 2**: This summary is too good.
- **Jacky Hsueh · 2026-07-10T18:08:33.000Z · 👍 1**: A very fair and balanced article.
- **Bing Qli · 2026-07-10T18:06:56.000Z · 👍 1**: Good
- **Rinko · 2026-07-10T18:05:17.000Z · 👍 1**: Well said, thanks for sharing.
