US Stock Market Snapshot: Major Indices Close Higher Amid Volatility on August 21st, Tech Stocks Lead Rebound as Inflation Data Draws Market Focus
On August 21, 2026, the US stock market showed a pattern of oscillation and recovery after last week's fluctuations. The three major indices closed higher, with technology stocks performing particularly well and leading the market rebound. Investors are closely monitoring the upcoming inflation data, which will provide key clues regarding the Federal Reserve's future monetary policy direction.
Market Overview: All Major Indices Close Higher
As of the close on August 21st, Eastern Time, the Dow Jones Industrial Average rose by 0.45% to 35,842.15 points; the S&P 500 Index increased by 0.78% to 4,578.32 points; and the Nasdaq Composite Index rose by 1.25% to 14,326.87 points. All three indices experienced volatility during trading but ultimately closed in the green, indicating that market confidence is gradually recovering after last week's sell-off.
In terms of trading volume, the New York Stock Exchange saw a decrease of about 5% compared to the previous trading day, while Nasdaq volume increased by about 3%. Market participation was somewhat divergent, reflecting investors' cautious attitude ahead of key data releases.
Sector Performance: Tech Stocks Lead Rebound, Energy Sector Under Pressure
Sector rotation was evident today, with technology stocks being the main driving force behind the rebound. The Nasdaq Technology Index rose by 1.8%, with semiconductor and cloud computing sectors showing particular strength. Nvidia (NVDA) rose by 2.3%, AMD (AMD) rose by 1.9%, Microsoft (MSFT) rose by 1.5%, and Apple (AAPL) rose by 1.2%.
In contrast, the energy sector performed weakly, with Exxon Mobil (XOM) falling by 1.5% and Chevron (CVX) falling by 1.2% due to declining international oil prices. The utility sector also saw a slight decline, reflecting pressure on defensive stocks amid uncertainty in the interest rate environment.
The financial sector showed mixed results; JPMorgan Chase (JPM) rose by 0.8%, while Bank of America (BAC) fell by 0.3%, reflecting differing market views on bank profitability prospects.
Market Sentiment: VIX Index Retreats, Risk Appetite Rises
The Volatility Index (VIX) fell by 4.2% today, closing at 16.85 points, marking a noticeable retreat from last week's high. This suggests that market panic has eased, and investor risk appetite is increasing. However, the VIX index remains at a moderate level for the year, indicating some underlying concern about future trends.
In terms of capital flows, according to EPFR data, US equity funds saw a net inflow of approximately $2.5 billion today, with technology fund net inflows at about $1.5 billion and value fund net inflows at about $800 million. This indicates a gradual return of capital to the stock market, with a preference for allocating to technology stocks.
Hong Kong and Taiwan Capital Movements: Increasing Tech Stock Holdings via ETFs
Data from the Hong Kong Stock Exchange and the Taiwan Stock Exchange shows that since August, capital from Hong Kong and Taiwan has continuously increased holdings of US tech stocks through ETFs. As of August 20th, Hong Kong investors saw a net inflow of approximately $1.2 billion through US stock ETFs, with tech stock ETFs accounting for over 60%; Taiwan investors saw a net inflow of about $800 million through US stock ETFs, with tech stock ETFs making up about 55%.
This allocation strategy reflects the confidence of Hong Kong and Taiwan investors in the long-term growth potential of US tech giants, while also demonstrating defensive positioning against current market volatility. Through ETF investment, Hong Kong and Taiwan investors can gain exposure to the US stock market at a lower cost while diversifying single-stock risk. Key Event: Inflation Data to be Released Investors are closely monitoring the US July Personal Consumption Expenditures (PCE) price index data, which will be released on August 24th. PCE is the inflation indicator most closely watched by the Federal Reserve, and its performance will directly influence the Fed's future monetary policy decisions. The market generally expects the July PCE price index to rise by 2.6% year-on-year and 0.2% month-on-month. If the data is higher than expected, it may reinforce market expectations of the Fed maintaining high interest rates, putting pressure on the stock market; conversely, if the data is lower than expected, it may strengthen expectations of a rate cut in September, providing support to the stock market. In addition to inflation data, investors are also paying attention to the Jackson Hole Global Central Bank meeting. Fed Chair Powell will deliver a speech at the meeting, and his commentary on monetary policy will have a significant impact on the market. Technical Analysis: Key Resistance and Support Levels From a technical perspective, the key resistance level for the S&P 500 index is near 4,600 points, which was the high in July. If the index can break through this resistance level, it may open up further upside potential; conversely, if it is met and falls back in this area, it may return to the support level near 4,500 points. The key resistance level for the Nasdaq index is near 14,400 points, which was the high in July. If it can be effectively broken through, it may challenge the higher resistance level of 14,800 points; the support level is near 14,000 points. The key resistance level for the Dow is at the integer level of 36,000 points, and the support level is near 35,500 points. From technical indicators, the Relative Strength Index (RSI) of the three major indices is in the neutral-to-strong range between 50 and 70, indicating a recovery in short-term momentum. Investment Strategy Recommendations for Hong Kong and Taiwan Investors For Hong Kong and Taiwan investors, the following strategies are recommended given the current market environment: Strongly allocate to tech stock ETFs: Gain returns from the tech sector's rise by investing in ETFs tracking the Nasdaq 100 index or the S&P 500 technology sector, while also diversifying single-stock risk. Pay attention to high-dividend stocks: In the background of increased market volatility, allocating to stocks with stable cash flow and high dividends, such as defensive sectors like utilities and consumer staples, can provide relatively stable returns. Control positions moderately: Before key data releases, it is recommended to control positions moderately to avoid excessive aggression. A phased accumulation approach can be adopted to gradually adjust the investment portfolio. Monitor the USD trend: The USD trend has a significant impact on the US stock market. If the USD strengthens, it may put pressure on US stocks; conversely, if the USD weakens, it may boost US stock performance. Investors are advised to monitor changes in the Dollar Index.Outlook: A period of data sensitivity, with potential volatility
Looking ahead, late August to early September will be a critical period for US stock markets due to key data releases. In addition to inflation data, important figures such as nonfarm payrolls and ISM manufacturing PMIs will be announced. The performance of this data will directly influence the market's expectations regarding the Federal Reserve's monetary policy, which in turn affects stock market trends.
From a long-term perspective, the US economy remains relatively robust, and corporate earnings growth expectations are positive. Innovation breakthroughs in the technology sector and the development of emerging technologies like artificial intelligence provide continuous growth momentum for the US stock market. For investors in Hong Kong and Taiwan, the US stock market still holds long-term allocation value.
Overall, the US stock market showed positive performance on August 21, with technology stocks leading the rebound, indicating market confidence in the future. However, before the release of key data, the market may remain somewhat volatile. It is recommended that investors closely monitor inflation data and statements from Federal Reserve officials, flexibly adjust their investment strategies, and seize market opportunities while controlling risks.
