Group 1 - The report indicates that over the past two months, the value style has strengthened significantly, with financial, cyclical, and consumer sectors rotating in performance [2][10][11] - The core reason for this style diffusion is attributed to the performance window before year-end, where sectors lack high-frequency quarterly reports to validate performance, leading to volatility driven mainly by valuation and expectations [2][10] - Historical context shows that in the second half of 2014, a liquidity bull market saw a shift from TMT to value, with cyclical and financial sectors performing well, although this trend was short-lived [2][10][18] Group 2 - The report notes that the current style diffusion is still in a phase driven by valuation, expectations, and capital inflow, which is expected to last at least 1-2 quarters [2][10][25] - For the style diffusion to transition into an annual-level market, the profitability logic of value stocks needs to be validated [2][10][25] - The report suggests that in the later stages of the liquidity bull market, the technology sector, which has a stronger long-term industrial logic, may return to prominence before the stabilization of value stock fundamentals [2][10][25] Group 3 - The report highlights that the financial sector is currently undervalued, with a high probability of outperforming as resident capital accelerates inflow [29][34] - The electrical equipment sector is noted for its potential growth, benefiting from investments in the AI industry and improving supply-demand dynamics [29][34] - The cyclical sector, particularly steel and chemicals, is expected to see opportunities due to stabilizing supply policies and potential demand recovery [29][34]
