科技股重挫，英伟达大跌，美股崩了，特斯拉跌7%，A股今日如何走

Core Viewpoint - The A-share market demonstrates resilience against the backdrop of a significant decline in the US stock market, with historical data indicating a low correlation between the Nasdaq and the Shanghai Composite Index [1][3][5]. Market Performance - The US stock market experienced a sharp decline, with the Nasdaq falling by 2.29%, the S&P 500 down by 1.66%, and the Dow Jones also decreasing by 1.66%. Notably, Tesla dropped nearly 7% and Nvidia fell by 3.58% [3]. - In contrast, the A-share market showed a strong performance, with all three major indices rising significantly, and the Shanghai Composite Index maintaining the 4000-point level [5]. Policy Environment - The A-share market's relative independence is attributed to the ongoing supportive macroeconomic policies in China, contrasting with tightening measures in the US and Europe. There are rising expectations for further policy support ahead of the Central Economic Work Conference [5][10]. - The valuation advantage of A-shares, with the CSI 300 index's price-to-earnings ratio at 12.5 times and a dividend yield of 2.83%, attracts funds seeking safety amid global asset scarcity [5][10]. Investment Opportunities - The market is witnessing a rotation among policy-sensitive sectors, with AI applications, solid-state battery concepts, and cyclical sectors like titanium dioxide and phosphorus chemicals showing strength [7][8]. - Historical data suggests that A-shares have lower correlation with US market movements, indicating potential for valuation increases when US fundamentals weaken while Chinese fundamentals improve [8][10]. Market Sentiment and Participation - Market sentiment remains stable, with no signs of panic selling, as investors focus on domestic economic improvements rather than external market fluctuations [8][11]. - Trading volumes have remained active, with daily turnover exceeding 1 trillion yuan, reflecting high market participation and confidence despite external pressures [11]. Long-term Outlook - Professional investors believe that the current market levels present long-term investment value, with a shift towards value investing and a reduction in speculative behavior [11]. - The resilience of quality assets during external shocks is highlighted, suggesting that companies that withstand current market challenges are likely to excel in future performance [11].
