Core Viewpoint - The article discusses the recent trends in the Consumer Price Index (CPI) and its implications for economic conditions and industry performance, indicating a potential shift towards a mild inflation period driven by policy stimuli and seasonal factors [2][3]. CPI Trends and Economic Phases - In July, the CPI increased by 0.4% month-on-month, reversing a previous decline, suggesting a possible mild inflation phase ahead due to consumption subsidies and social security policies [2]. - Historical data shows that a rising CPI typically indicates economic recovery and increased demand, while a declining CPI reflects insufficient domestic demand and deflationary pressures [3][4]. Industry Performance During CPI Phases - During periods of rising CPI, essential consumer goods tend to perform well due to their price transmission capabilities, while resource sectors benefit from inflation expectations [4]. - Conversely, in declining CPI phases, defensive sectors show resilience, supported by policy easing and infrastructure investments [4]. Historical CPI Trends - The article outlines various CPI phases from 2015 to 2024, highlighting periods of inflation and deflation, with specific CPI ranges and characteristics for each phase [5]. Industry Performance Analysis - In the CPI rising period from March 2016 to February 2017, the CSI 300 index rose by 19.99%, while the CSI 2000 index increased by 31.56%, indicating a preference for small-cap stocks [7]. - From February 2019 to January 2020, both indices showed balanced performance, with the CSI 300 rising by 25.06% and the CSI 2000 by 28.04% [9]. - In the CPI rising period from January 2021 to February 2022, the CSI 300 fell by 12.08%, while the CSI 2000 rose by 18.85%, again favoring small-cap stocks [11]. Market Dynamics and Investment Strategies - The article suggests that during rising CPI periods, small-cap stocks may continue to outperform large-cap indices, indicating a potential shift in investment strategies [12]. - The concept of a "slow bull" market is introduced, emphasizing that market dynamics may favor small-cap and sector-specific performances rather than broad market rallies [12].
