• The report tracks various types of ETFs on a daily basis, categorizing them into "broad-based" and "thematic" ETFs based on the indices they track, such as CSI 300, CSI 500, and industry/style indices like non-bank financials and dividends[2] - The RSI (Relative Strength Index) is calculated using the formula: $ RSI = 100 - 100 / (1 + RS) $, where RS is the average gain divided by the average loss over a 12-day period. RSI values above 70 indicate an overbought market, while values below 30 indicate an oversold market[2] - The net subscription amount is calculated using the formula: $ NETBUY(T) = NAV(T) - NAV(T-1) * (1 + R(T)) $, where NETBUY(T) is the net subscription amount, NAV(T-1) is the ETF's net asset value from the previous trading day, and R(T) is the return on the current day[2] Quantitative Models and Construction Methods 1. Model Name: RSI (Relative Strength Index) - Construction Idea: Measures the speed and change of price movements to identify overbought or oversold conditions - Construction Process: - Calculate the average gain and average loss over a 12-day period - Compute the RS (Relative Strength) as the ratio of average gain to average loss - Apply the formula: $ RSI = 100 - 100 / (1 + RS) $ - Evaluation: Useful for identifying potential reversal points in the market[2] 2. Model Name: Net Subscription Amount - Construction Idea: Measures the net inflow or outflow of funds into an ETF - Construction Process: - Calculate the net asset value (NAV) of the ETF for the current and previous trading days - Compute the return (R) for the current day - Apply the formula: $ NETBUY(T) = NAV(T) - NAV(T-1) * (1 + R(T)) $ - Evaluation: Indicates investor sentiment and fund flow dynamics[2] Model Backtesting Results 1.
