• The report primarily focuses on tracking and analyzing the performance of broad-based indices in the A-share market, including their daily investment dynamics, moving averages, turnover rates, risk premiums, PE-TTM, dividend yields, and net asset break rates[1][2][4] - The turnover rate of the indices is calculated as the sum of the free-float market capitalization of constituent stocks multiplied by their turnover rates, divided by the total free-float market capitalization of the constituent stocks[17] - The risk premium is measured relative to the yield of 10-year government bonds, serving as a reference for risk-free rates, to evaluate the relative investment value and deviation of the indices[27][29] - The PE-TTM (Price-to-Earnings Trailing Twelve Months) is used as a valuation reference to assess the investment value of the indices at the current point in time[37][41] - Dividend yield is tracked to reflect the cash dividend return rate, which is particularly significant during market downturns as high dividend yields often act as a safe haven[46][51] - The net asset break rate is defined as the proportion of stocks with a price-to-book ratio below 1, indicating undervaluation in the market[52][55]
