Group 1 - The core conclusion of the report is to explore which industries that have underperformed for three consecutive years have a higher probability of reversal in the coming year. It highlights that industries like beauty care, basic chemicals, and social services are currently close to their historical longest periods of underperformance [2][3][10] - The report identifies that defensive industries such as environmental protection, public utilities, and transportation are more likely to exhibit prolonged underperformance due to their weak cyclical nature and low beta characteristics. These industries tend to show a "prolonged decline" feature [2][3][10] - The report indicates that the trend of negative excess returns in public utility sectors is attributed to the small-cap stocks within these sectors, which lack both offensive characteristics during bull markets and stable dividend attributes. The divergence between industry leaders and small-cap stocks has become more pronounced since 2017 [3][24] Group 2 - The report provides statistical analysis from 2007 to 2025, showing that the probability of an industry that has underperformed for three consecutive years winning in the fourth year is inversely related to its historical performance. This suggests that industries with a long history of weak performance are likely to continue this trend [3][10] - The report notes that the current industries that have underperformed for three years and are close to their historical longest underperformance periods include beauty care, basic chemicals, and social services. It also mentions that the food and beverage, agriculture, forestry, animal husbandry, fishery, social services, and pharmaceutical biotechnology sectors have a higher probability of winning in the fourth year [4][38] - The report emphasizes that the monthly trading volume of public utilities, environmental protection, and transportation has been decreasing as a proportion of total A-share trading volume, indicating a long-term downward trend in liquidity for these sectors [4][24][37]
