#股票交易分享挑战 U.S. stocks recap: All three major indexes fell, while memory stocks rose!
All three major U.S. stock indexes fell
I. Closing performance of the three major indexes
- Dow Jones Industrial Average: closed at 53460 points, down 0.51%, hitting a new low for nearly two weeks
- S&P 500 Index: closed at 7747 points, down 0.52%
- Nasdaq Composite Index: closed at 26647 points, down 0.32%; semiconductor and memory sectors offset the decline, resulting in a significantly smaller drop than the Dow and S&P
II. Key drivers behind the market decline
1. Rising geopolitical tensions in the Middle East pushed up inflation and U.S. Treasury yields
The window for U.S.-Iran talks expired, with dim prospects for negotiations on a long-term agreement, while shipping through the Strait of Hormuz plunged sharply; the market worried that shrinking crude oil supply would push up inflation, prompting funds to sell U.S. Treasuries for safety. The 30-year U.S. Treasury yield rose to its highest level since 2007, while the 10-year yield climbed 5 basis points to 4.68%; high interest rates pressured growth-stock valuations, weighing on the broader market. International oil prices surged, with WTI hitting a new high for the month and Brent holding above $90, further reinforcing inflation concerns.
2. Earlier rate-cut expectations temporarily cooled
The market had previously bet that the Federal Reserve would begin cutting rates in September, but after U.S. Treasury yields rose, investors reassessed the risk of an inflation rebound caused by high oil prices. Rate-cut trades saw profit-taking, triggering a broad pullback in the market at high levels.3. Profit-taking in indexes at elevated levels
The three major indexes had previously advanced steadily and approached record highs, accumulating substantial unrealized gains, while geopolitical risks prompted investors to lock in profits.
III. Sharp sector divergence: Chip and semiconductor stocks rose against the trend, while major technology leaders broadly fell
1) Biggest decliners: The seven technology giants (AI core heavyweights collectively weakened)
Meta led large-cap technology stocks, plunging 3.5%; Microsoft fell more than 3%; Apple, Google, Amazon, Tesla, and Nvidia all closed slightly lower.
Differences among investors emerged: the market worried whether AI companies’ continued massive capital expenditures could sustainably translate into revenue returns, prompting funds to flow out of high-valuation internet and software leaders.
2) Surging against the trend: Memory chips, optical communications, and AI hardware all exploded higher
The Philadelphia Semiconductor Index surged 1.6%, returning to bull-market territory and becoming the only strong theme across the market. The core logic: OpenAI’s long-term computing-power procurement commitments have continued to restore expectations for AI hardware demand.
- Memory chips: SanDisk +9%, Western Digital +5%, Micron Technology +4%, Kioxia ADR surged more than 14%
- Optical communications: Coherent nearly 8%, Lumentum +4.6%, Corning +4%
- AI chipmakers: Cerebras surged 15%, announcing that it would provide hardware for OpenAI’s next-generation GPT computing power; Broadcom rose more than 5.8%; Palantir rose 8.47%
3) Other sectors
The communications services sector ranked last overall; industrials were relatively resilient; value-oriented financial and consumer stocks weakened in tandem.
IV. Moves in popular individual stocks
Gainers
1. SPCX (SpaceX): rebounded 4.5% as institutions raised their price targets
2. MSTR (MicroStrategy): +7.19%, with Bitcoin breaking above $64k and lifting crypto-related stocks
3. Soluna (SLNH): +12.34%, with crypto-mining computing power benefiting from rising coin prices
Decliners
1. CVNA (Carvana): the biggest decliner among S&P 500 components, plunging 7.3%
2. BRK.B (Berkshire Hathaway): down 1.23%, as rate-cut expectations reduced the appeal of high-cash-value stocks
V. Chinese concept stocks
Significant divergence:
- Gainers: NIO and Li Auto rose more than 1%
- Decliners: MINISO plunged 8%, while JD.com weakened slightly by more than 1%
VI. Movements across other major asset classes
1. Gold: rose 0.8% to a new two-month high as geopolitical safe-haven buying entered the market
2. U.S. Dollar Index: fell for three consecutive sessions, touching a two-month low intraday; offshore yuan broke above 6.74 intraday, reaching a new three-year high
3. Cryptocurrencies: Bitcoin rose above $64k intraday, with a 3% daily trading range
VII. Market focuses for the coming period
1. U.S. August PPI inflation data (released on August 18), which will directly affect judgments on the Federal Reserve’s rate-cut pace;
2. A dense schedule of retail-company earnings reports this week, testing the resilience of U.S. consumer spending;
3. Developments in the Middle East and the sustainability of crude oil supply; persistently rising oil prices could limit the Federal Reserve’s room for easing.
