量化观市：量化视角下如何把握春节前躁动？

• The report highlights the performance of eight major stock selection factors across different stock pools (All A-shares, CSI 300, CSI 500, and CSI 1000). Among these, the value factor (17.88%) and size factor (11.88%) showed strong IC mean performance, while reversal and quality factors performed relatively weaker[54][55][66] - Small-cap value style dominated the market, with the small-cap size factor performing strongly across the entire market. Value factors also showed positive performance, indicating a market preference for low valuation stocks. Additionally, technical and low-volatility factors performed well, while consensus expectation factors weakened due to reduced focus on high-performance expectation sectors[54][55][66] - The report provides detailed definitions for various factors, such as size (logarithm of market capitalization), value (e.g., book-to-price ratio, earnings-to-price ratio), growth (e.g., net income growth), quality (e.g., ROE, gross margin), consensus expectation (e.g., changes in expected EPS), technical (e.g., volume skewness), volatility (e.g., 60-day return standard deviation), and reversal (e.g., 20-day return)[66][67] - The report also tracks the performance of convertible bond selection factors, which are constructed based on the relationship between convertible bonds and their underlying stocks. Factors include stock consensus expectation, stock value, and convertible bond valuation (e.g., parity premium rate). Among these, stock consensus expectation and stock value factors achieved higher IC mean values in the past week[59][60][62]
