#SK海力士ADR溢价超30% SK Hynix surges 27% overnight — global compute power revelry: Where is the money for AI running to?

On the first day of entering the hottest part of summer, hotter than the weather is chip stocks.
You wake up and global chips explode.
The U.S. stock close on July 14 made countless investors rub their eyes again and again.
SK Hynix’s U.S. stock ADR surged 27.29% in a single day, closing at $193.92, with its market cap jumping by more than $27k overnight. What does that mean? Three days ago, it only just listed on Nasdaq at a $149 offering price, opened at $170, and closed at $168 — in just three trading days, the ADR premium versus the underlying Korean shares soared from 3% to 51%.
Not just it alone. Micron rose nearly 5%, SanDisk rose over 5%, Nvidia rose 4%, AMD rose over 5%, and the Philadelphia Semiconductor Index jumped 2.54%. The entire memory and compute-power segment was as if it had been ignited.
Meanwhile on the China A-share side, it wasn’t idle either. The ChiNext index soared 3.43%, and the compute hardware and PCB segments sparked a daily-limit-up surge. Total trading value across both markets expanded to 2.7 trillion yuan.
One side is global chip giants partying together, the other is China’s A-share compute-power sector being aggressively bid up. Behind this, is it short-term speculation, or a signal of a bigger trend?
Triple positive catalysts coincide, and the chip stocks’ surge is not accidental
Breaking it down, this chip rally has three pushes stacking at the same time.
First: AI storage demand really has exploded.
SK Hynix’s HBM4 (high-bandwidth memory) has completed certification and has started official mass shipments to Nvidia’s new-generation AI compute equipment, with further volume ramp in September. How scarce is this? In the global HBM market, SK Hynix alone holds 58% of the share; Samsung and Micron have 21% each. The expansion cycle is 4 to 6 months, and capacity releases can’t possibly keep up with demand.
Research firm SemiAnalysis expects SK Hynix’s DRAM average price in Q2 to rise about 45% quarter-over-quarter. Barclays even set a $330 target price—70% above the current share price. Wall Street’s consensus is that the shortage of memory chips will last at least until 2028.
Second: U.S. inflation cools more than expected, and rate-hike panic fades.
The data released on July 14 showed the U.S. June CPI year-over-year was only 3.5% (prior 4.2%), and the month-over-month figure fell by 0.4%—the first time in six years that month-over-month growth turned negative. The moment the inflation data came out, market expectations for Fed rate hikes collapsed instantly: the probability of a July hike fell from 42% to 17% in a flash.
What does this mean? Expectations for looser liquidity heat up, and money begins to pour into technology growth sectors at large scale. High-multiple chip stocks are exactly the kinds of targets investors love to pile into.
Third: ADR options list, and incremental capital floods in crazily.
On July 14, SK Hynix’s ADR options were officially listed and began trading on the CBOE. Trading volume on day one reached 150k contracts, and two-thirds of the funds bought short-term call options. Add in leveraged ETFs launched by institutions like GraniteShares and ProShares, and it’s like opening multiple “adding-to-positions channels” for global capital.
A supply-constrained stock + bullish call options + leveraged ETFs = a 27% surge. This isn’t coincidental—it’s the result of capital voting with its feet.
A-share compute-power sector: not chasing the trend, but resonating
After the overnight U.S. stock chip rally, today’s A-share compute-power sector isn’t just following blindly—it has independent logic behind it.
First, the window for domestic substitution is opening. Amid the global memory price surge, domestic companies like Yangtze Memory and CXMT are accelerating their catch-up. Tomorrow (July 16), the domestic memory leader CXMT will submit for issuance on the STAR Market (Science and Technology Innovation Board). The offer price is 8.66 yuan per share, with a market value of about 579.2 billion yuan. The strategic placement brings in key core industry-chain companies such as Ramtron, Tongfu Microelectronics, and Nuvoton Micro. This is a concentrated debut of China’s domestic memory industry chain.
Second, performance is real. The PCB segment that hit the daily limit today is backed by actual earnings. LiTong Electronic expects net profit to increase 1,172% to 1,368% in the first half; FiberHome expects 711% to 914% growth; Tongfu Microelectronics expects 288% to 337% growth; and Dongshan Precision expects 283% to 296% growth. These numbers are not just numbers on paper—they’re real orders driven by AI server demand.
Third, policy is ramping up. The third phase of the Big Fund (the National Integrated Circuit Industry Investment Fund II) continues to roll out 344 billion yuan, with 70% of the funds going to semiconductor equipment and core materials. Seven ministries and commissions released an integrated circuit breakthrough plan, calling for new AI compute centers to purchase domestic AI chips with up to a 30% fiscal subsidy.
The policy signal is very clear: domestic compute power is a national-level strategic direction.
Macroeconomic backdrop: structural divergence behind 4.7% GDP
Today another important data point was also released: first-half GDP grew 4.7% year-over-year, with Q1 at 5.0% and Q2 at 4.3%.
Looking closer, both strengths and pressures are present:
Exports outperform expectations: first-half imports and exports reached 25.47 trillion yuan, up 16.9% year-over-year, with June single-month growth of 24.2%. Electrical and mechanical product exports grew 20.1%, accounting for 63.5%—showing China’s manufacturing competitiveness remains strong.
Consumption is weak: first-half retail sales (social retail sales) grew only 1.3%, and June year-over-year rose just 1.0%. Domestic demand is still the biggest shortcoming. Investment structure diverges: total fixed-asset investment fell 5.7%, but investment in high-tech industries rose 4.6%; aerospace and aircraft manufacturing grew 23.3%; computer and office equipment grew 8.1%; and information services industry grew 15.5%. Real estate continues to weigh down the economy: development investment fell 18%, and sales area dropped 11.6%.
In plain terms: the traditional economy is still finding its footing, but AI and high-end manufacturing are pushing upward with all their might. The central bank also sees this, which is why today it directly injected 1.4 trillion yuan of a 6-month buyout-style reverse repo, releasing a large amount of liquidity to provide a tailwind for the second half.
What does this mean for us?
Putting today’s information together, there are a few threads worth paying attention to:
First, the investment logic for AI infrastructure is shifting from “telling stories” to “backing it with performance.” SK Hynix’s 27% surge isn’t about炒概念—it’s driven by performance: HBM4 mass deliveries and a 45% quarter-over-quarter rise in average DRAM prices. The streak of daily-limit rallies in A-share compute-power stocks also isn’t just following the trend—LiTong Electronic’s earnings-growth expectation of 1,172% is providing the support. The market is moving from “betting on expectations” to “betting on delivery.”
Second, global capital is re-pricing “AI certainty.” U.S. CPI cools → expectations of rate hikes fade → technology stock valuations repair → compute hardware becomes the top-choice target. This chain works in both U.S. stocks and A-shares at the same time. Over the coming months, as long as inflation doesn’t rebound and AI demand doesn’t ease, opportunities along this chain haven’t finished yet.
Third, geopolitical risk is the biggest variable. The conflict between Iran and the U.S. keeps escalating; the U.S. military restarts the Strait of Hormuz blockade; Iran announces the memorandum of understanding is void; and oil tankers are attacked. WTI crude has already broken $79, and Brent has broken $84. Gold has broken $4,050. If the conflict further worsens, the surge in oil prices would raise global inflation, directly disrupting expectations for Fed rate cuts, and technology stock valuations would face pressure too.
So on one side is the certainty of AI compute power growth, and on the other is the uncertainty risk from geopolitical conflict. The current strategy may be to maintain positioning along the certainty line of AI infrastructure growth, while also watching high-dividend names as a defensive allocation.
Today is the first day of entering the hottest period, the 40-day long “Sanfu” (three hottest spells). Survive these 40 days and it’s autumn. Aren’t the market’s “frost” days just like that too? $SKHY ‌
