天风策略：科技主线的短期扰动与长期趋势

Core Viewpoint - The technology sector has experienced a convergence of excess returns over the past month (January 15, 2026 - February 13, 2026), but not all sub-sectors are weakening uniformly. The excess drag is attributed to AI applications influenced by overseas SaaS, while optimistic earnings guidance from recent financial reports has stabilized SaaS stock prices, indicating that the phase of panic may be nearing its end [1][3][9]. Group 1: Market Performance and Trends - Since mid-January, the technology sector has shown relative convergence with the broader market, but not all sub-sectors are experiencing weakness. AI computing reached new highs in the last trading week before the holiday, while AI applications have shown deeper corrections and weaker recoveries, remaining over 5% below their mid-January peak [3][10]. - The software development sector in A-shares has retreated over 13% from its January 14 high, influenced by rapid declines in U.S. SaaS stocks on January 12 and January 25 due to the impact of ClaudeCowork and OpenClaw [3][10]. - The technology sector's ability to remain a key theme for the year will depend on industry trends and actual earnings performance, with a dual drive from technology and cyclical recovery expected to favor technology if earnings verification occurs [3][10]. Group 2: Sector Allocation and Configuration - The current allocation in the electronics industry exceeds 20%, with the overall TMT sector over-allocated by more than 17 percentage points. However, the current level of allocation does not directly impact future excess returns [4][11]. - The marginal changes in allocation are more closely linked to the current quarter's excess, with limited significance for the next quarter's guidance. The excess return convergence threshold for technology sub-sectors is at 2.5 or higher, with most sub-sectors below this level [4][11]. Group 3: Identifying Certainty in Technology - To identify certainty within the technology sector, two dimensions can be explored: forward-looking financial indicators and industry cycle trends. The "deferred revenue + contract liabilities" metric can provide insights into order conditions, highlighting sectors with accelerating improvements or sustained high growth over the past two quarters [5][12]. - Key sectors showing accelerated improvement include semiconductors, communication equipment, and digital chip design, while those with sustained high growth include consumer electronics and optical components. The DRAM and NAND Flash contract prices have been rising rapidly since Q4 2025, supported by long-term demand in AI servers and enterprise storage [5][12].
