看懂这些，把握跨年行情

Group 1 - The core viewpoint of the article emphasizes that the "cross-year market" period is characterized by significant industry rotation and style switching rather than a straightforward market trend, with historical patterns indicating mixed performance across indices [2][4]. - Over the past decade, major broad-based indices have shown an average decline during the cross-year period, with the average returns for the CSI 500, CSI 1000, and National 2000 indices in January being -4.71%, -6.67%, and -6.68% respectively, indicating a win rate below 50% [2][4]. - The Shanghai Composite 50 and CSI 300 indices have shown average returns of -0.72% and -1.54% in January, with a win rate of 50% over the last ten years, suggesting a relatively stronger performance compared to smaller indices [2][4]. Group 2 - The article highlights that the characteristics of the cross-year market are not indicative of a general beta market trend, but rather a "defensive December and strong differentiation in January" structure, with defensive sectors performing better in December [7][12]. - In January, the banking sector has consistently outperformed other sectors, maintaining a position among the top five in terms of monthly returns, except for 2020 and 2023 [7][12]. - The average returns for most sectors in January have been negative, with many sectors showing win rates of only 30-40%, indicating a lack of broad-based gains and a tendency for performance differentiation [7][12]. Group 3 - Historical statistics suggest that the cross-year phase is not a favorable period for quantitative long strategies to achieve excess returns, but rather exposes differences in strategy concentration, drawdown control, and volatility adaptation [12]. - For investors holding quantitative long private equity funds, the focus during the cross-year period should be on assessing the ability of their products to maintain net value stability in a volatile and differentiated environment [12]. - From an asset allocation perspective, it is advisable to consider complementary configurations of styles and assets to smooth out portfolio volatility, particularly given the banking sector's relative strength in January [12].
