今年市场的两条主线：AI和地缘、反内卷

Group 1 - The core theme for A-share pricing in 2026 revolves around AI and geopolitical factors, reflecting the U.S. focus on technology for growth and geopolitical strategies for elections, while another underpriced theme is "anti-involution," corresponding to China's push for reform-driven momentum [1][8] - Since the beginning of 2026, the A-share market has shown a "good start" with a cumulative increase of 5.2% in the Wind All A index and an average daily trading volume exceeding 3 trillion yuan, with the Sci-Tech 50, CSI 500, and National 2000 indices leading the gains at 11.9%, 11.3%, and 9.6% respectively [2] - The leading sectors include media, computer, non-ferrous metals, and military industries, with year-to-date increases of 16.0%, 14.0%, 14.0%, and 9.0%, indicating that the current market focus is on "AI and geopolitical" themes [2] Group 2 - The impact of AI is evident not only in the A-share market but also in marginal changes in the macro economy, with the PPI in December 2025 rising by 0.2% month-on-month, marking the highest increase since 2024, driven in part by AI's contribution to price improvements in non-ferrous and technology sectors [5][8] - In December 2025, prices in the non-ferrous metal mining and smelting industries rose by 3.7% and 2.8% respectively, with AI-driven electricity demand significantly boosting prices for metals like copper, silver, lithium, and cobalt [5] - The prices of external storage devices and integrated circuits increased by 15.3% and 2.4% respectively in December 2025, with high-end AI chips occupying advanced process resources, leading to structural tensions in chip availability [7] Group 3 - The improvement in PPI reflects strategic choices made by China and the U.S. in the current global macro context, which are expected to become two main pricing themes for A-shares in 2026: "AI and geopolitics" and "anti-involution" [8] - The "anti-involution" theme is entering a new phase in 2026, with recent discussions emphasizing the need to address malicious low-price dumping and promote healthy competition [9] - Recent policy changes indicate a clearer execution strategy for "anti-involution," focusing on "quality over price" in industries like photovoltaics and energy storage, with regulatory bodies emphasizing quality standards and price monitoring [10][12] Group 4 - The cancellation of export tax rebates for photovoltaic products and the reduction of tax rates for battery products reflect the national-level implementation of "anti-involution," aimed at allowing competitive companies to raise prices and retain funds for domestic investment [11] - Local governments are shifting their competitive advantages from unsustainable policy incentives to sustainable business environments and professional service capabilities, indicating a broader commitment to "anti-involution" practices [12] - Strengthened regulatory enforcement against monopolistic and unfair competition behaviors signals an acceleration of "anti-involution," aiming to enhance market order and promote a virtuous cycle of quality and pricing in the industry [12]
