收评：放量大涨后突现4000股普跌，市场在玩哪一出？

Core Viewpoint - The market is experiencing a rapid shift from a bullish sentiment to a bearish one, characterized by significant structural differentiation rather than a single-direction bull market [1]. Market Characteristics - The market is described as having "ice and fire," with a clear divide between strong and weak sectors [3]. - The technology growth sector, particularly CPO (optical modules), remains robust, driven by the global AI industry revolution and demand for computing power [4]. - Conversely, sectors like non-ferrous metals and local stocks in Hainan are facing declines, influenced by commodity market fluctuations and a lack of strong logical support [4]. Reasons for Market Differentiation - Insufficient incremental capital and intensified competition among existing funds are leading to a focus on a few strong consensus sectors, such as AI computing power, resulting in a "bloodletting" effect on weaker sectors [5]. - The strong performance of the CPO sector is supported by the dual narratives of the global AI race and domestic substitution, while sectors like Hainan are more susceptible to short-term policy or sentiment-driven movements [5]. Strategic Recommendations - Maintain focus on core sectors like CPO and semiconductor equipment, tolerating volatility as long as the underlying industry logic remains intact [6]. - Distinguish between trends and fluctuations, being cautious not to chase short-term gains or losses based on daily market movements [6]. - Control positions and wait for clearer signals before making aggressive moves, looking for opportunities in core technology sectors during reasonable pullbacks or potential new upward trends after market stabilization [6].
