WDC/STX小幅上涨无具体存储催化，仅为Nvidia财报带动的AI基建sympathy move，SK海力士ADR反向下跌，不构成亚洲存储链交易级事件

# 美股盘后催化 8/11: 存储和硬盘链分化偏强，WDC与STX上涨但SK海力士ADR下跌，不能简单归为全存储利好

- 美股会话: 2026-08-26

## 本催化相关美股真实收盘行情

- 规划器没有给出可取价的美股 ticker；必须联网核实具体 mover。

## 亚太映射假设（仅候选，必须查证）

- 三星电子 (待归一) [KR/供应商/mixed]: DRAM/NAND周期若改善利好存储业务，但HBM份额和传统存储价格需分开判断。；核验问题: 核实DRAM、NAND、HBM各自价格与库存数据。
- 南亚科 (待归一) [TW/同源本地股/positive]: 若传统DRAM价格或库存周期改善，利好利基或标准DRAM链。；核验问题: 核实当日是否有现货报价、合约价或渠道库存变化。

## 必答问题

TRADING DAY Hot inflation cools sentiment
URL: https://www.reuters.com/commentary/reuters-open-interest/global-markets-trading-day-graphic-2026-08-26/
The dollar and U.S. Treasury yields ticked higher and Wall Street treaded water on Wednesday after U.S. inflation figures reminded investors that the Fed could raise interest rates soon. Trading ranges were narrow, however, as investors awaited Nvidia's results and looked ahead to a keynote speech from Fed Chair Kevin Warsh later this week.

If ​you have more time to read, here are a few articles I recommend to help you make sense of what happened in markets ‌today.

1. Nvidia forecasts quarterly revenue above estimates

2. US inflation remains sticky in July; second-quarter GDP growth unrevised at 1.5%

3. Anxious investors hope for clarity on Warsh's Fed plan at Jackson Hole

4. Bill Gates, alarmed by AI, has policy ideas he wants to discuss with China's Xi

5. Meta agrees to pay $18 billion to settle US lawsuits over children's social media addiction

Today's Key Market Moves

STOCKS: South Korea +1%, Japan and China +0.5%; Europe, UK ​and Wall Street all close to flat.

SECTORS/SHARES: Seven sectors on the S&P 500 fall, four rise. Healthcare -1%, industrials +1%. Moderna -5%, Eli Lilly -4%, Honeywell +2.3%.

FX: Dollar +0.3%, biggest rise in 2 ​weeks. Swedish crown -1%, biggest fall in 2 months. Colombian peso eyes worst week since April.

BONDS: U.S. yields rise 1-3 bps, 2s/30s ⁠curve flattest close since July Fed meeting. Reasonable 5-year auction - bid/cover ratio 2.37, highest this year.

COMMODITIES/METALS: U.S. copper futures hit record high $6.75/lb. Oil slips, Brent -1%. Gold -1%. U.S. natgas +3% to 1-month ​high.

Today's Talking Points:

Hotter in July

U.S. inflation as measured by the PCE index, the Fed's preferred measure, came in slightly hotter last month than expected. The 0.2% month-on-month ​increase in headline inflation was above the 0.1% forecast, and the annual rate edged up to 3.7%. The unrounded monthly increase in core was 0.246%, close to 0.3%.

Rate hike expectations barely budged, with traders still pricing in a 60-40 probability of a rise next month. The recent signals of intent from Treasury Secretary Scott Bessent to lower bond yields at the long end of the ​curve seem to be working, which may explain the bond market's muted reaction. But there's no doubting it — inflation is sticky. Over to Fed Chair Kevin Warsh and ​his Jackson Hole address on Friday.

Corporate v. consumer

The second reading of U.S. national accounts released on Wednesday showed that corporate profits as a share of GDP rose to new record ‌highs in ⁠Q2. One measure — there are several ways to slice the data — showed after-tax income increased to 12.1% of GDP. But can consumer spending help maintain those inflated margins?

Spending in Q2 was strong, and it could point to a broader re-acceleration in growth for the second half of the year. But the personal savings rate rose in Q2 to 3.0% from a historically low 2.6%. This is still extremely low, and suggests consumers will have to rely more on credit than savings in the coming months. Inflation-adjusted ​spending was flat in July — will that ​be a brief pause for breath, ⁠or a more lasting lull?

Watching the chips roll in

Nvidia, the $5 trillion chipmaking AI behemoth, released its latest results after the bell on Wednesday. The world's most valuable company reported Q2 revenue and earnings that beat estimates, and its Q3 revenue outlook was ​also brighter than the analyst consensus. Interestingly, its Q3 revenue outlook does not include any data center chip sales from ​China.

But shares fell in ⁠post-market trading, by as much as 3%, because the gross margin is expected to dip to 74% in Q3 from 75% in Q2. Essentially, it is costing Nvidia more to generate these bumper revenues and profits. A one percentage point reduction in margins, especially from such an elevated starting point, seems trifling. But could it mark a top, of sorts?

⁠What could ​move markets tomorrow?

South Korea interest rate decision

U.S. Treasury sells $44 billion of 7-year notes at auction

Nasdaq Futures Rise 1% on Nvidia’s Sales Outlook: Markets Wrap
URL: https://www.bloomberg.com/news/articles/2026-08-26/nasdaq-futures-rise-on-bullish-nvidia-sales-growth-markets-wrap
Futures for the tech-heavy Nasdaq 100 Index gained after Nvidia Corp. gave a bullish sales outlook, easing concerns that the artificial intelligence spending boom is losing momentum.

Contracts for the US benchmark rose about 1% in early Thursday trading after Chief Financial Officer Colette Kress signaled strong sales growth in fiscal 2028, sending Nvidia shares higher after hours. Asian equity-index futures were mixed, pointing to gains in South Korea and declines in Japan and Australia. An $809 billion exchange-traded fund tracking the S&P 500 fluctuated after the close of regular trading.

Still, caution lingered in bond markets as traders boosted bets on a Federal Reserve interest-rate hike this year after a key inflation gauge remained above the Fed’s target. Short-dated Treasuries underperformed in the US session and the dollar rose, with money markets fully pricing an increase by December.

Nvidia’s outlook offered fresh evidence that spending on AI infrastructure remains robust, potentially easing concerns that the investment boom is losing steam. The upbeat forecast comes as investors increasingly scrutinize whether heavy AI spending can sustain earnings growth after a volatile stretch for technology stocks.

“We expect to grow revenue by approximately 70% in fiscal 2028,” Kress said during a post-earnings conference call. Analysts have projected an increase of about 45% for that year, according to data compiled by Bloomberg.

Nvidia shares had fallen at the start of extended trading after the chipmaker forecast current-period revenue of $108 billion, plus or minus 2%. While that topped the $105.2 billion average analyst estimate, some projections exceeded $110 billion, according to data compiled by Bloomberg.

The shares then reversed course, climbing more than 5% after Nvidia delivered a bullish sales outlook for 2028.

Elsewhere, oil eased in a choppy session as traders weighed progress on diplomatic efforts to resume shipping through the Strait of Hormuz against fresh risks of a global supply squeeze.

Investors got a fresh read on inflation Wednesday. The core personal consumption expenditures price index, which excludes food and energy, rose 0.2% from the prior month and 3.3% from a year earlier. Inflation-adjusted consumer spending was flat after gains in May and June.

The broader PCE price index rose 3.7% from a year earlier, remaining well above the Fed’s 2% goal. Combined with other data pointing to a cooling economy in July, the figures bolstered the case for policymakers to keep interest rates unchanged for now.

Attention now turns to the Jackson Hole Economic Symposium, which begins Friday. Kevin Warsh will deliver his first major speech as Fed chair, giving investors fresh clues on the policy outlook after facing criticism over a lack of clarity on his views about the economy.

“The number of dissenters at the next meeting may grow because the month-over-month readings are getting worse, but we believe enough of the FOMC will want to wait to see more data before making a decision to raise rates next month,” said Chris Zaccarelli, chief investment officer at Northlight Asset Management.

Corporate Highlights:

CrowdStrike Holdings Inc. forecast revenue figures for the full year that exceeded analysts’ estimates, evidence that the cybersecurity industry continues to see demand driven by threats from artificial intelligence. Salesforce Inc. gave an outlook for strong revenue expansion and deepened its partnership with Anthropic PBC, reassuring investors that it can compete successfully in the AI era. Anthropic PBC has agreed to spend $45 billion to rent AI cloud computing power from Nscale’s flagship data center development in West Virginia, the latest move in an effort to secure capacity for its expanding business in advance of going public.
