量化观市：外资休整缩量博弈，聚焦政策主线

• The report discusses a rotation model for micro-cap stocks, which uses the relative net value of micro-cap stocks to the "Mao Index" as a key indicator. If the relative net value is above its 243-day moving average, it suggests investing in micro-cap stocks; otherwise, it suggests investing in the Mao Index. Additionally, the 20-day closing price slope of both indices is used to determine the direction of rotation, favoring the index with a positive slope when the directions differ [19][24][26] - A timing indicator is constructed based on the 10-year government bond yield (threshold: 0.3) and the volatility congestion rate of micro-cap stocks (threshold: 0.55). If either indicator reaches its threshold, a closing signal is triggered to manage risk [19][24][20] - The report evaluates eight major stock selection factors across different stock pools (All A-shares, CSI 300, CSI 500, and CSI 1000). Among these, the value factor (20.46%), volatility factor (16.11%), and technical factor (13.68%) show strong IC mean performance, while the growth factor (-5.65%) and consensus expectation factor (-2.16%) perform relatively weakly [46][47][48] - The report highlights that defensive value factors and volume-price factors (volatility and technical) performed strongly in the past week, reflecting a shift in market style towards low-valuation defensive strategies amid a volatile environment. Growth and consensus expectation factors, which previously performed well, experienced a pullback [46][47][48] - For convertible bonds, the report constructs quantitative bond-picking factors, including equity-related factors and valuation factors such as parity and floor premium rates. Among these, equity consensus expectation, equity value, and convertible bond valuation factors achieved higher IC mean values in the past week [54][55][56]
