量化择时周报：近半年趋势信号首次破坏，何时反弹？-20251019

• The report introduces a timing system model based on the distance between the 120-day long-term moving average and the 20-day short-term moving average of the WIND All A Index. The model's construction involves calculating the difference between the two moving averages, with the short-term average currently above the long-term average. The formula for the distance is expressed as: $ Distance = \frac{Short\ Term\ MA - Long\ Term\ MA}{Long\ Term\ MA} $ where Short Term MA represents the 20-day moving average and Long Term MA represents the 120-day moving average. The current distance is 12.26%, down from 12.89% last week, and remains significantly above the threshold of 3%[2][11][17] - The report evaluates the timing system model as effective in identifying market trends, noting that the recent shift from an upward trend to a volatile trend is captured by the model. The model's core observation focuses on changes in risk appetite during volatile periods[2][11][17] - The report highlights the "TWO BETA" model for industry allocation, which recommends focusing on technology sectors, including domestic computing power and the Hang Seng Internet sector. The model emphasizes policy-driven sectors such as photovoltaics and chemicals, alongside dividend assets[3][12][17] - The report suggests using a position management model to adjust stock allocation based on the WIND All A Index. The model recommends a 60% allocation for absolute return products, considering the index's PE at the 85th percentile and PB at the 50th percentile, indicating a medium valuation level[3][12][17] - The timing system model's backtesting results show that the current WIND All A Index trend line is at 6264 points, while the closing price is 6108 points, significantly below the trend line. The market's profitability effect indicator has turned negative for the first time in six months, signaling a potential end to the upward trend[2][11][17]
