Analysis of Hong Kong and US stock market on March 23: Tech stocks lead the drop, geopolitics + Fed become the core drag Core Summary: As of the close on March 23, 2026, the secondary markets of Hong Kong and US stocks collectively faced pressure, showing a volatile downward trend. The three major US stock indices all closed lower, with technology stocks leading the decline; the main Hong Kong stock indices fell sharply, with the Hang Seng Index and the Hang Seng Tech Index both dropping over 3%, indicating a clear transmission of panic sentiment from the Asia-Pacific market. This market volatility is primarily driven by Middle East geopolitical conflicts, hawkish policy signals from the Federal Reserve, and upward revisions to inflation expectations. Short-term market risk aversion has intensified, and sectoral divergence has increased. Today, Hong Kong stocks continued their decline, opening lower and closing lower throughout the day. Affected by overnight declines in US stocks, panic sentiment in the Asia-Pacific market, and the drag from technology stocks, the main indices fell sharply, trading volume expanded significantly, selling pressure was evident, and the overall trend was weak. **(I) Core Market Trends** As of the close, the performance of the main Hong Kong stock indices is as follows (Data source: Tonghuashun Financial Database): Index Abbreviation Closing Price Change (%) Change Turnover (HKD Billion) Hang Seng Index 24,382.47 \-3.54 \-894.85 3,686.77 Hang Seng Tech Index 4,712.48 \-3.28 \-159.90 828.87 Hang Seng China Enterprises Index 8,307.82 \-3.11 \-266.25 1,341.55 **(II) Key Sector and Stock Performance** 1\. Technology Sector: Leading the decline in Hong Kong stocks, heavyweight stocks collectively faced pressure. The Hang Seng Tech Index fell over 3%, with heavyweight stocks like Tencent Holdings (00700.HK), Alibaba (09988.HK), and Meituan-W (03690.HK) declining in sync. Affected by the sharp drop in US tech stocks and market risk aversion sentiment, funds significantly withdrew from the technology sector. 2\. Financial Sector: Also declined, with banking and insurance stocks performing weakly. Pressured by expectations of high interest rates from the Federal Reserve, Hong Kong's financial sector faced headwinds. HSBC Holdings (00005.HK) and AIA (01299.HK) saw slight declines, and market expectations for financial sector profits have been revised downward. 3\. Energy and Healthcare Sectors: Relatively resilient. The energy sector benefited from rising international oil prices, with some stocks gaining against the trend. Although the Hong Kong healthcare sector showed divergence, its overall performance was stronger than the broader market. Stocks like Akeso (09926.HK) and CSPC Pharmaceutical Group (01093.HK) maintained slight fluctuations, reflecting some defensive attributes to a certain extent. **(III) Analysis of Market Drivers** 1\. Transmission of Overnight US Stock Declines: The three major US stock indices all closed lower, with technology stocks plummeting. As a market with strong linkage, Hong Kong stocks were directly dragged down, opening lower and experiencing continued selling pressure. 2\. Spread of Panic Sentiment in Asia-Pacific Markets: The Nikkei 225 index plunged over 2,600 points intraday, and the KOSPI index triggered a circuit breaker. Overall panic sentiment was high in the Asia-Pacific market, leading to capital flight for safety, which weighed on Hong Kong stock performance. 3\. Geopolitical and Inflationary Pressures: Escalating geopolitical conflicts in the Middle East pushed up oil prices, coupled with the Federal Reserve raising inflation expectations. Market concerns about global economic growth prospects intensified. As an emerging market, Hong Kong stocks faced increased capital outflow pressure, further suppressing the market trend. ## **III. Market Summary and Investment Advice** Currently, the secondary markets of Hong Kong and US stocks are in a volatile downward trend overall. The core drivers are the escalation of Middle East geopolitical conflicts, hawkish policy signals from the Federal Reserve, and upward revisions to inflation expectations. Short-term market risk aversion has intensified, and sectoral divergence has increased. Valuations of US tech and growth stocks are under pressure, while the energy sector is strengthening against the trend. Hong Kong's main indices have fallen sharply, with the technology sector leading the decline, while defensive sectors (energy, healthcare) are relatively resilient. Investment Advice: Short-term market volatility has increased along with uncertainty. Investors are advised to remain cautious, control positions, and avoid high-valuation, high-volatility stocks. In the medium to long term, focus can be placed on the energy sector (benefiting from rising oil prices), defensive healthcare sector, and quality tech leaders with low valuations. Be alert to potential risks such as escalating geopolitical conflicts, changes in Federal Reserve policy, and inflation exceeding expectations.
