• The A-share sector rotation model is constructed using six factors: capital, valuation, sentiment, momentum, overbought/oversold, and profitability. The scoring system is based on these factors to evaluate the comprehensive scores of industries[4][19] - The capital factor uses the net inflow rate of industry funds as the main data source, while the valuation factor is based on the valuation percentile of the industry over the past year. Sentiment is derived from the proportion of rising constituent stocks, momentum is calculated using the MACD indicator, overbought/oversold is measured by the RSI indicator, and profitability is based on the consensus forecast EPS percentile of the industry over the past year[19] - The scoring results of the sector rotation model show that industries such as media, social services, and food & beverage have high comprehensive scores, while industries like real estate, building materials, and environmental protection have low scores[4][20][21] - The consensus stock selection model identifies high-growth industries at the secondary level of Shenwan classification over the past 30 days. It calculates momentum factors, valuation factors, and upward frequency using monthly stock data. Additionally, it incorporates high-frequency minute-level fund flow data to compute the similarity between fund flow changes and stock price trends. Stocks with the highest similarity in the top three secondary industries are selected[22] - The selected high-growth secondary industries for this period are industrial metals, home appliance components II, and energy metals. Stocks chosen include Chang Aluminum Co., Jintian Co., and Libba Co. among others[23] - The A-share sector rotation model scoring results indicate that the media industry achieved a total score of 8, social services scored 8, and food & beverage scored 7. Conversely, industries such as real estate and building materials scored -5, and environmental protection scored -4[21] - The consensus stock selection model outputs stocks such as Chang Aluminum Co. and Jintian Co. from the industrial metals sector, Tianyin Electromechanical and Samsung New Materials from the home appliance components II sector, and Shengxin Lithium Energy and Rongjie Co. from the energy metals sector[23]
