Savicoin US Stock Perpetual Daily Report | September 18, 2026 (Friday UTC+8)

Data as of: September 18, 2026, 08:00 (UTC+8)
Corresponding US stock trading date: September 17, 2026

1. Overnight US Stock Market

On September 17, the US stock market rebounded significantly, with all three major indices rising and technology stocks leading the gains.

The market was mainly driven by factors including the decline in crude oil prices, lower US Treasury yields, and investors gradually digesting the Federal Reserve’s interest rate hike decision.

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. US stocks initially came under pressure after the rate hike was announced, but market sentiment recovered significantly on September 17.

At the same time, international oil prices fell from their previous highs. Brent crude declined by approximately 1%, while the US 10-year Treasury yield fell to around 4.93%, easing some market concerns about energy costs and the high-interest-rate environment.

At the close:

Dow Jones Index:51,778.04(+0.61%)

S&P 500:7,637.76(+1.14%)

Nasdaq Composite Index:26,418.30(+1.69%)

The technology sector was the main driver of the day’s gains, with chip and AI-related stocks performing particularly strongly.

2. Savicoin Perpetual Contract Market

Note: The reference prices and percentage changes are based on the closing prices during the regular trading session of the corresponding US stocks/ETF on September 17. The actual execution prices of Savicoin US stock perpetual contracts may differ due to trading times, market liquidity, and market volatility.

3. Market Observations

Market trading dynamics changed significantly on September 17.

In the previous few trading sessions, the market mainly traded around:

Rising oil prices | Inflationary pressure | US Treasury yields | Federal Reserve rate hike

However, on Thursday the market began to shift towards:

Falling oil prices | Lower yields | Technology stock rebound | AI industry 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, they increased their allocation to technology stocks again after oil prices and Treasury yields declined.

The US 10-year Treasury yield fell to around 4.93%, breaking below the 5% threshold again and providing some relief for high-valuation growth stocks.

At the same time, Brent crude fell by approximately 1%, temporarily easing concerns about a continued rapid rise in energy prices.

Therefore, the short-term market focus remains on:

Federal Reserve policy | US Treasury yields | Crude oil prices | Inflation | AI technology stocks

4. Key Sector | AI and Semiconductors

The semiconductor sector strengthened significantly on September 17.

Among them, **Sandisk (SNDK)** rose considerably. Public market data showed that it gained more than 5% on the day, making it one of the most active stocks in the chip and memory sector.

At the same time, chip-related stocks including Intel, AMD, Micron, and Arm also rose significantly.

The market has refocused on the long-term demand for chips driven by AI infrastructure and data centre construction.

The market’s current areas of focus in the AI industry chain mainly include:

AI computing demand

Data centre capital expenditure

High-performance memory demand

AI server construction

Earnings growth for chip manufacturers

Among them:

• NVDA: Focus on AI chip and data centre demand;
• SNDK: Focus on memory demand from AI data centres;
• MSFT / AMZN: Focus on cloud computing and AI infrastructure investment;
• META: Focus on AI applications and advertising monetisation.

5. Key News for September 18

1 | US stocks rebound strongly, with technology stocks leading again

On September 17, the Nasdaq Composite Index rose 1.69%, significantly outperforming the Dow Jones and S&P 500 indices.

Technology stocks were the main driver of the market’s gains, with chip, AI, and large technology companies generally strengthening.

Short-term market risk appetite recovered to some extent.

2 | The market begins to reprice after the Federal Reserve’s rate hike

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 assess:

Whether rates will continue to rise | Inflation trends | The labour market | Long-term US Treasury yields

The rate hike itself has been implemented, and the market’s focus will gradually shift from “whether rates will rise” to “the future interest rate path”.

3 | 10-year US Treasury yield falls to around 4.93%

On September 17, the US 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 focus is needed on:

10-year US Treasury yield | Real interest rates | US Dollar Index | Nasdaq performance

If the yield breaks 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 by approximately 1%.

However, oil prices remain relatively high, and market attention to the situation in the Middle East and energy supplies has not completely faded.

Therefore, the market will continue to monitor:

Crude oil prices | The situation in the Middle East | Energy supplies | US inflation

If oil prices rise rapidly again, concerns about inflation and interest rate policy may return.

5 | US employment data remains resilient

The number of US initial jobless claims released on September 17 was 196,000, below the previous figure of 206,000.

The labour market continues to show some resilience.

This means the market currently needs to pay attention to:

Labour market resilience + inflationary pressure + a high-interest-rate environment

If economic data continues to remain strong, it may affect market expectations regarding future monetary policy.

6. What to Watch Today

On September 18, the market will focus on the following five themes:

Federal Reserve policy | US Treasury yields | Crude oil prices | AI technology stocks | Quarterly derivatives expiry

Key technology stocks to watch:

NVDA | META | MSFT | AAPL | AMZN | TSLA | SNDK

Among them:

NVDA
Focus on AI chip and data centre demand, as well as whether the semiconductor sector’s rebound can continue.

SNDK
Recent volatility has been relatively high. Focus on AI data centre memory demand and fund 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 centre capital expenditure.

MSFT
Focus on AI investment, Azure cloud business, and enterprise AI applications.

TSLA
Continue to monitor fund flows and company-related news in a highly volatile environment.

7. Special Focus Today | Quarterly Derivatives Expiry

September 18 is the last US stock trading day of this week and falls within a period of concentrated quarterly derivatives expiry.

The expiry of quarterly options and related derivatives may lead to:

Increased trading volume | Greater intraday volatility | Rapid index rallies or declines | Late-session fund rebalancing

Therefore, price fluctuations in today’s market may be more pronounced than on ordinary trading days.

For US stock perpetual contracts, special attention should be paid to rapid intraday movements and changes in liquidity.

8. Core Market Logic Today

The trading logic of the current US stock market is undergoing a phased transition:

Phase One

Rising oil prices → Inflation concerns → Rising US Treasury yields → Pressure on technology stocks

Phase Two

Federal Reserve rate hike implemented → Falling oil prices → Declining US Treasury yields → Technology stock rebound

Therefore, the market will focus on the following on September 18:

Whether oil prices can continue to decline

Whether the 10-year US Treasury yield can remain below 5%

Whether the technology stock rebound can continue

Whether funds will continue flowing into the AI and semiconductor sectors

Whether subsequent Federal Reserve policy signals will become further hawkish

If oil prices and US Treasury yields continue to decline, the valuation pressure facing growth stocks may ease further. If oil prices rise rapidly again while yields break above 5% again, market volatility may increase once more.

10. Risk Warning

US stock perpetual contracts are leveraged trading products, and prices may fluctuate significantly.

The current market remains affected by multiple factors, including:

Federal Reserve policy | Crude oil prices | Inflation | US Treasury yields | Geopolitics | AI industry expectations

In particular, against the backdrop of the Federal Reserve’s recent adjustment to its interest rate policy and the quarterly derivatives expiry, the market may experience significant short-term price volatility.

Large technology stocks and semiconductor assets are receiving considerable market attention, and prices may rise or fall rapidly after major news is released.

Please manage your position sizes and leverage appropriately, and pay close attention to market liquidity, price volatility, and the risks of leveraged trading.
