大调整！如何防守？

Core Viewpoint - The recent market decline is a normal adjustment due to short-term profit-taking, not indicative of systemic risk, with a focus on the concentrated risk in previously hot sectors [2][3]. Group 1: Market Performance - The three major indices fell over 2%, with the Shanghai Composite Index down 2.48%, Shenzhen Component down 2.69%, and ChiNext down 2.46%, while the STAR 50 Index dropped over 3% [2]. - More than 4,600 stocks declined, with 123 stocks hitting the daily limit down, and the total trading volume in the Shanghai and Shenzhen markets was 2.58 trillion, a decrease of 250.8 billion from the previous trading day [2]. Group 2: Causes of Adjustment - The decline was triggered by significant fluctuations in the global precious metals market, leading to panic selling in the A-share precious metals sector, compounded by a natural decline in risk appetite as the Spring Festival holiday approaches [3]. - Despite the drop, the trading volume remained at a trillion-level scale, indicating that the reduction was due to profit-taking rather than panic selling, with defensive sectors like liquor, electric grid equipment, and banking seeing net inflows [3]. Group 3: Sector-Specific Risks - The precious metals sector was the hardest hit, with many stocks hitting the limit down due to high previous gains and concentrated leverage, exacerbated by margin ratio increases triggering forced liquidations [4]. - The semiconductor sector also experienced significant declines, driven by a disconnect between valuations and earnings, as many companies reported substantial profit declines while still being valued at historical highs [4]. - Other cyclical sectors like non-ferrous metals and oil and gas also weakened, sharing the commonality of crowded trading structures and excessive profit accumulation without solid earnings support [4]. Group 4: Future Outlook - It is advisable to temporarily avoid high-volatility hot sectors and focus on low-valuation defensive sectors and areas with policy support, waiting for the risks in hot sectors to be fully released before making investment decisions [5]. - Following the holiday, a return to a stabilizing market rhythm is expected as market sentiment improves and liquidity returns [5].
