Core Viewpoint - The report from Guosen Securities emphasizes the importance of focusing on investment opportunities that are immune to "involution," highlighting three high-barrier sectors: monopolistic industries like public utilities and rare earths, industries with exclusive products and global competitiveness in hard technology, and sectors where AI accelerates the replacement of repetitive tasks [1][2][3]. Group 1: High-Barrier Industries - Monopolistic barrier assets, such as public utilities (electricity, water) and strategic rare resources (like rare earths), effectively avoid intense market competition and provide stable cash flow and pricing power, making them excellent defensive investments [2][11]. - Global competitive assets are characterized by technological innovation and product exclusivity, allowing companies to successfully expand into overseas markets and create unique advantages, primarily found in high-end manufacturing and hard technology sectors [2][11]. - AI-driven efficiency revolution assets are transforming traditional industries by replacing repetitive labor, significantly enhancing productivity and accelerating the "involution" process in certain sectors [3][19]. Group 2: Market Phases of "Involution" - The "involution" market is currently transitioning from the first phase (involution 1.0) to the second phase (involution 2.0), where the focus shifts from broad industry recovery to individual stock selection based on self-discipline and competitive differentiation [4][6]. - The first phase is characterized by supply-side contraction leading to a supply-demand gap, benefiting upstream resource sectors like steel and coal [4][6]. - The second phase sees a focus on high-quality companies that can achieve market share and profitability recovery through strict production discipline, while smaller firms must innovate and create unique competitive advantages [4][6]. Group 3: Long-Term Investment Strategy - The long-term strategy emphasizes investing in industries with natural high barriers to entry, which can provide stable and higher returns compared to short-term "involution" opportunities [11][13]. - Historical data indicates that monopolistic industries, such as public utilities and strategic rare resources, have shown resilience and sustained performance compared to emerging industries that have faced downturns [11][13]. - The report suggests prioritizing sectors with high entry barriers, such as public utilities and strategic resources, which offer stable cash flows and are less affected by economic cycles [11][13].

Core Insights - The current "anti-involution" market trend represents a phase of reversal from difficulties, characterized by a clear four-stage evolution, alternating between systematic market opportunities (β) and individual stock excess returns (α) [3][5] - Investors are encouraged to focus on high-barrier assets that are naturally immune to "involution," identifying three core long-term investment themes: monopolistic barrier assets, globally competitive assets, and AI-enabled efficiency revolution assets [3][4][19] Group 1: Four Stages of "Anti-Involution" Market - The first stage (Anti-Involution 1.0) is driven by supply-side contraction expectations, benefiting upstream resource sectors like steel and coal, leading to a typical β opportunity [5][6] - The second stage (Anti-Involution 2.0) sees a shift in focus from industry-wide gains to individual stock differentiation, where leading firms gain market share through strict production discipline, creating α opportunities [6][7] - The third stage (Anti-Involution 3.0) involves a fundamental improvement in supply-demand relationships, leading to a recovery in overall corporate profits and product prices, marking a new round of market upturn [7][8] - The fourth stage (Anti-Involution 4.0) features the emergence of new core assets in a stabilized competitive landscape, driven by technological innovations and global expansion [8][9] Group 2: Current Market Positioning - The market is transitioning from Anti-Involution 1.0 to 2.0, necessitating a dual focus on both β opportunities in specific sectors and the identification of high-quality stocks with strong α characteristics [8][13] - The current "anti-involution" differs fundamentally from the 2015 policy-driven "three reductions" approach, relying more on market-driven self-discipline rather than administrative mandates [8][13] Group 3: Long-Term Investment Themes - The report emphasizes the importance of investing in industries with natural high barriers to entry, such as public utilities and strategic rare resources, which provide stable cash flows and are less affected by economic cycles [19][27] - The three core elements supporting high-barrier industries include licensing barriers, resource barriers, and network effect barriers, which create exclusive pricing power and stable cash flows [27][28] - Companies that successfully "go global" and break overseas monopolies are identified as key players in the "anti-involution" narrative, particularly in high-tech sectors [29][30] Group 4: AI Empowerment - The rise of AI technology is seen as a transformative force accelerating the "anti-involution" process by enhancing productivity and driving market clearing [33][35] - Industries that can effectively leverage AI to reduce costs and reshape competitive dynamics are positioned to thrive in the evolving market landscape [35][36]
