TEBBIT U.S. Stock Perpetual Daily Report｜September 18, 2026 (Friday)
Data as of:2026/9/18 08:00 (UTC+8)
Corresponding U.S. stock trading date:2026/9/17
I. Overnight U.S. Stock Market
On September 17, U.S. stocks rebounded noticeably, with all three major indexes rising and technology stocks leading the gains.
The market was mainly driven by factors including falling oil prices, declining U.S. Treasury yields, and investors gradually digesting the Federal Reserve’s rate-hike decision.
Previously, on September 16, the Federal Reserve raised the benchmark interest rate by 25 basis points to 3.75%–4.00%, marking the first rate hike since 2023. After the rate-hike announcement, U.S. stocks came under pressure temporarily, but market sentiment recovered notably on September 17.
Meanwhile, international oil prices retreated from their previous highs, with Brent crude falling approximately 1%, while the U.S. 10-year Treasury yield declined to approximately 4.93%, easing some market concerns about energy costs and the high-interest-rate environment.
At the close:
Dow Jones Industrial Average: 51,778.04 points (up 316.14 points, or 0.61%)
S&P 500 Index: 7,637.76 points (up 85.95 points, or 1.14%)
Nasdaq Composite Index: 26,418.30 points (up sharply by 439.88 points, or 1.69%)

III. Market Observations
Market trading logic changed notably on September 17.
During the previous several trading sessions, the market mainly focused on:
Rising oil prices｜Inflationary pressure｜U.S. Treasury yields｜Federal Reserve rate hikes
.
On Thursday, however, the market began to shift toward:
Falling oil prices｜Declining yields｜Technology stock rebound｜AI supply-chain recovery
On the first full trading day after the Federal Reserve’s rate hike, investors did not continue to increase the selling pressure from the previous day. Instead, after oil prices and bond yields fell, they increased allocations to technology stocks again.
The U.S. 10-year Treasury yield fell to approximately 4.93%, breaking below the 5% threshold again and providing some relief for high-valuation growth stocks.
Meanwhile, Brent crude fell approximately 1%, temporarily easing concerns about a sustained rapid rise in energy prices.
Therefore, the core short-term market focus remains on:
Federal Reserve policy｜U.S. Treasury yields｜Oil prices｜Inflation｜AI technology stocks
IV. Key Sectors｜AI and Semiconductors
On September 17, the semiconductor sector strengthened notably.
Among them, **SanDisk (SNDK)** rose significantly. Public market data showed that it gained more than 5% on the day, making it one of the more active names in the chip and memory sectors.
Meanwhile, chip-related stocks including Intel, AMD, Micron, Arm also rose notably.
The market refocused on the long-term chip demand generated by AI infrastructure and data-center construction.
Current market attention toward the AI supply chain mainly includes:
AI computing-power demand
Data-center capital expenditure
High-performance memory demand
AI server construction
Earnings growth among chip manufacturers
Among them:
NVDA Focuses on AI chips and data-center demand;
SNDK focuses on the memory demand generated by AI data centers;
MSFT / AMZN focuses on cloud computing and AI infrastructure investment;
META focuses on AI applications and advertising monetization.
V. Key News for September 18
1｜U.S. stocks rebound strongly, with technology stocks leading again
On September 17, the Nasdaq Composite rose 1.69%, significantly outperforming the Dow Jones and S&P 500 indexes.
Technology stocks were the primary driving force behind the market’s gains, with chips, AI, and large technology companies generally strengthening.
Short-term market risk appetite recovered to some extent.
2｜After the Federal Reserve’s rate hike, the market began to reprice
On September 16, the Federal Reserve raised the benchmark interest rate by 25 basis points to 3.75%–4.00%, marking the first rate hike since 2023.
The market now needs to further observe:
Whether rates will continue to rise｜Inflation trends｜The labour market｜Long-term U.S. Treasury yields
The rate hike itself has already been implemented. The market’s focus will gradually shift from “whether rates will rise” to “the future interest-rate path”.
3｜10-year U.S. Treasury yield falls to around 4.93%
On September 17, the U.S. 10-year Treasury yield fell to approximately 4.93%.
Compared with the level above 5% on the previous trading day, the decline in yields significantly eased valuation pressure on growth stocks.
For technology stocks, continued attention should be paid to:
10-year U.S. Treasury yield｜Real interest rates｜U.S. dollar index｜Nasdaq trend
If yields break above 5% again, high-valuation technology stocks may once again face valuation pressure.
4｜Oil prices retreat from highs but remain elevated
On September 17, Brent crude prices fell approximately 1%.
However, oil prices remain at relatively high levels, and market attention to the situation in the Middle East and energy supplies has not completely disappeared.
Therefore, continued observation is needed of:
Oil prices｜The situation in the Middle East｜Energy supplies｜U.S. inflation
If oil prices rise rapidly again, concerns about inflation and interest-rate policy may increase again.
5｜U.S. employment data remains resilient
Initial U.S. jobless claims released on September 17 were 196,000, below the previous figure of 206,000.
The labour market continues to demonstrate some resilience.
This means the market currently needs to focus simultaneously on:
Employment resilience + Inflationary pressure + High-interest-rate environment
If economic data remains strong, it may affect the market’s assessment of future monetary policy.
VI. Today’s Focus
On September 18, the market will focus on the following five themes:
Federal Reserve policy｜U.S. Treasury yields｜Oil prices｜AI technology stocks｜Quarterly derivatives expiration
Key technology stocks to watch:
NVDA｜META｜MSFT｜AAPL｜AMZN｜TSLA｜SNDK
Among them:
NVDA
Focus on AI chips and data-center demand, as well as whether the semiconductor-sector rebound can continue.
SNDK
Recent volatility has been high. Focus on AI data-center memory demand and capital flows.
META
Focus on AI assistants, AI applications, and advertising business growth.
AAPL
Focus on market feedback following new product launches and subsequent sales expectations.
AMZN
Focus on AI infrastructure, cloud business, and data-center capital expenditure.
MSFT
Focus on AI investment, Azure cloud business, and enterprise AI applications.
TSLA
Continue to monitor capital flows and company-related news amid high volatility.
VII. Special Focus Today｜Quarterly Derivatives Expiration
September 18 is the last U.S. stock trading day of this week and falls within the quarterly derivatives expiration window.
The expiration of quarterly options and related derivatives may lead to:
Higher trading volume｜Greater intraday volatility｜Rapid index rallies or declines｜End-of-day capital rebalancing
Therefore, market price fluctuations today may be more pronounced than on ordinary trading days.
For U.S. stock perpetual contracts, particular attention should be paid to rapid intraday fluctuations and changes in liquidity.
VIII. Core Market Logic Today
The trading logic of the current U.S. stock market is undergoing a phased transition:
Phase One:
Rising oil prices → Inflation concerns → Rising U.S. Treasury yields → Pressure on technology stocks
Phase Two:
Federal Reserve rate hike implemented → Falling oil prices → Declining U.S. Treasury yields → Technology stock rebound
Therefore, the market will focus on the following on September 18:
Whether oil prices can continue to fall
10-year U.S. Treasury yield and whether it can remain below 5%
Whether the technology stock rebound can continue
AI and whether capital will continue flowing into the semiconductor sector
Whether the Federal Reserve’s subsequent policy signals will become further restrictive
If oil prices and U.S. Treasury yields continue to fall, valuation pressure on growth stocks may ease further. If oil prices rise rapidly again while yields break above 5% again, market volatility may increase once more.
IX. Trading Session Reminder
U.S. stock trading session｜21:30–04:00 (Beijing Time)
Market liquidity and activity are relatively high during regular trading hours.
Pre-market and after-hours｜16:00–21:30 / 04:00–08:00
Liquidity is relatively lower before and after regular trading hours. Prices may fluctuate rapidly before and after the release of major economic data, company announcements, and breaking news.
September 18 is Friday, and U.S. stocks will trade normally.
At the same time, as it falls within the quarterly derivatives expiration window, intraday and end-of-day price fluctuations may be amplified.
Actual trading hours and market data are subject to the information displayed on the TEBBIT platform.
X. Risk Warning
U.S. stock perpetual contracts are leveraged trading products, and prices may fluctuate significantly.
The current market remains affected by multiple factors, including:
Federal Reserve policy｜Oil prices｜Inflation｜U.S. Treasury yields｜Geopolitics｜AI industry expectations
.
In particular, against the backdrop of the Federal Reserve’s recent adjustment to interest-rate policy and the quarterly derivatives expiration, the market may experience significant short-term price volatility.
Large technology stocks and semiconductor instruments are receiving considerable market attention, and prices may rise or fall rapidly following the release of significant news.
Please manage position sizes and leverage appropriately, and pay close attention to market liquidity, price volatility, and the risks of leveraged trading.
