Core Viewpoint - The relationship between the automotive industry's prosperity (sales growth) and the valuation of the automotive sector is complex, influenced by both declining total growth and rapid advancements in AI technology [1][7]. Group 1: Relationship Between Valuation and Prosperity - There is a relationship between automotive sector valuation and industry prosperity, with valuation leading prosperity by about one month [1][10]. - Historically, years of high sales growth have correlated with improved automotive sector performance, indicating a long-term positive correlation between valuation and prosperity [7][10]. - The correlation between valuation and prosperity has weakened since 2019, indicating a decoupling effect where high prosperity does not necessarily drive high valuation [2][15]. Group 2: Decoupling and Asymmetrical Effects - The decoupling effect suggests that prosperity is a sufficient but not necessary condition for valuation, meaning high valuation can exist without high prosperity [2][15]. - Asymmetrical effects indicate that while high prosperity can drive valuation increases, low prosperity does not necessarily lead to valuation declines, allowing for structural opportunities to support valuation [29][30]. Group 3: Three-Cycle Determinism - The automotive industry is influenced by three cycles: macroeconomic, industrial technology, and policy cycles, which together affect the industry's fundamentals and valuation [2][33]. - The shift in dominant cycles from macroeconomic and policy cycles to industrial technology cycles has led to a redefinition of valuation logic, focusing on quality upgrades rather than scale expansion [34][45]. Group 4: Future Outlook Post-2025 - The automotive industry is expected to enter a phase of low growth normalization, with total sales remaining stable and structural opportunities emerging from AI technology and smart vehicles [3][21]. - Valuation is anticipated to remain stable despite fluctuations in sales growth, indicating a continued decoupling trend [21][25].
