Zheshang Securities(SH:601878) Xin Lang Cai Jing·2025-12-28 08:51Core Viewpoint - The market is experiencing a gradual upward trend driven by the strong performance of the A500 ETF, the booming commercial aerospace sector, and the continued strength of optical modules. The conclusion of a medium-term bullish outlook for A-shares, characterized as a "systematic slow bull," is deemed to have high confidence, although the sustainability of the driving factors needs to be verified in the short term [1][4][9]. Market Overview - Major indices collectively rose, with the CSI 500 leading in gains during the week of December 22 to December 26, 2025. The market showed broad-based gains, although the dividend consumption sector remained generally weak. Trading volume in Shanghai and Shenzhen saw a slight decline, and most stock index futures contracts were trading at a discount. The margin financing balance increased slightly, with a higher proportion of financing purchases and net inflows into stock ETFs. The valuation of the ChiNext index is relatively low, and the downward energy model is at a normal level [2][7]. Market Attribution - The IPO guidance status of Blue Arrow Aerospace has changed to "guidance work completed," and SpaceX has confirmed preparations for a potential IPO in 2026. The central bank has released a one-time personal credit repair policy to help individuals rebuild credit. Additionally, the central bank's monetary policy committee held its fourth-quarter meeting, emphasizing the need to "maintain the stability of the capital market" [3][8]. Future Market Outlook - The market has shifted from a state of indecision to one favorable for bulls, primarily due to three driving factors: the strong performance of the CSI A500 ETF, which saw total shares increase by 39.89 billion and 67.23 billion over the past week and two weeks, respectively; the ongoing boom in commercial aerospace, which has significantly boosted growth indices; and the continued strength of optical modules, which supports the innovation index. While these factors have shifted the market towards a bullish trend and laid the foundation for upward movement in the first half of the following year, their sustainability remains uncertain. The medium-term bullish outlook for A-shares is supported, but short-term developments require careful observation [4][9]. Investment Strategy - Based on the assessment of a medium-term bullish outlook and the need for short-term observation, it is advised to maintain current positions and avoid chasing after high-performing stocks, especially those with significant gains this year. If a situation similar to the "golden pit" seen earlier this year arises, it is recommended to actively increase allocations at lower prices. The focus should be on the brokerage sector, which has shown signs of lagging and potential for share expansion. Additionally, attention should be given to the Hang Seng Technology Index, which has undergone sufficient adjustments and formed a daily MACD divergence. A strategy of "light index, heavy stock" is suggested, with a focus on low-performing stocks above the annual line [5][10].
