高切低还会延续多久？

Market Overview - The market experienced a significant decline on October 17, with the Shanghai Composite Index dropping by 1.95% and the ChiNext Index falling by 3.36%. The total trading volume for the A-shares remained at 1.95 trillion, unchanged from the previous trading day [2] - All sectors saw a decline, with previously strong sectors like power equipment (-4.99%), electronics (-4.17%), and machinery (-3.69%) leading the losses. In contrast, banking (-0.32%), transportation (-0.53%), and textiles (-0.61%) showed relative resilience [2] Strategy Analysis - The current growth industry cycle is transitioning into a healthy adjustment phase, characterized by a significant differentiation in performance among sectors. The strong growth style is experiencing a pullback, consistent with the characteristics of a healthy adjustment period where "growth styles rise and fall significantly" [3] - The transition from the first phase of the growth industry cycle to the second phase is marked by a healthy adjustment period. This occurs when two or more of the key drivers—performance, liquidity, and catalysts—show signs of marginal weakening. Currently, liquidity is constrained due to recent adjustments in margin financing rates by brokerages, and catalysts are weakened by increasing trade tensions between China and the U.S. [3][4] Future Outlook - Historically, healthy adjustment periods are typically short, lasting around one month with maximum adjustments of 10-20%. A potential opportunity for the second phase of the market could arise around early November, driven by the expected strong performance in Q3 earnings reports and possible easing of U.S.-China trade tensions during the APEC summit [4] - The upcoming Fourth Plenary Session and the anticipated 25 basis point rate cut by the Federal Reserve are also expected to boost market sentiment [4] Investment Strategy - In the short term, the market is expected to continue experiencing "high-low cuts," while the long-term trend remains focused on the growth industry cycle and sectors with strong performance support. Potential sectors for rotation include finance (banking, insurance), utilities, steel, petrochemicals, food and beverage, and home appliances [8] - The core long-term investment themes include the establishment of a new growth industry cycle, particularly in AI computing infrastructure, which is expected to have a significant impact on sectors such as TMT, computing (CPO/PCB/liquid cooling/fiber optics), applications (robots/games/software), and military industry [8][9] - The second key theme focuses on sectors with strong performance support, including power equipment (wind power/storage/batteries/power supply), non-ferrous metals (rare earths/precious metals), and machinery (construction machinery). These sectors are expected to benefit from high demand and favorable market conditions [9]
