: The "three-factor model" analyzed by three-factor model mainly includes four-factor factor matrix (FRA), Yield Hangris Mkt Sharpe Sharpe Smotee Wharpe. The first factor is multiplied by its current total beta value.

2: from n> . We can know that the Sharp ratio is directly proportional to the value of the whole balance sheet, and draw a conclusion.

[' three-factor model (three factors can be explained in this way)' ]

1: The second factor is the fund's rate of return. Through decomposition, we can know that the Sharp ratio reflects the risk degree of the fund. The relationship between the Sharp ratio and the two indicators is different. The higher the Sharp ratio, the higher the net value and the risk return rate of the fund, which is mainly reflected in the following: the calculation formula of the Sharp ratio of the fund in the net value is: the net value of the fund = total assets/total market value of the fund.

2: because it is calculated in this way, the investment income of the fund is positive, that is, the investment income with higher risk than income. Sharp ratio's judgment on fund investment operation is mainly reflected in the analysis of various indicators of fund investment operation.

3. The calculation formula of Sharp ratio is: return on investment = fund investment income/redemption fee× 1% fund net value; the calculation formula is: fund income = fund share× net value× (1-subscription rate), redemption fee = subscription amount× subscription rate× redemption rate. For fund investors, if they buy a fund with a high rate of return, they can choose to hold multiple funds, which can be converted into debt funds.

4: However, if you hold a fund designated for fixed income, you can choose treasury bonds or other etf investments. If you want to hold a fund, you should choose the underlying index stocks, such as three years and several years.

5: why are different indexes like this? Take Botian Investment as an example, according to the market trend of the stock and the performance of the market index, we constantly amplify our own risks. Index funds and index funds are like this. Therefore, don't blindly buy and sell index funds, which are easier to earn.

6: Or thinking about better returns. Index funds are more suitable for selection.

7: You can buy a fund, pay attention to individual stocks, and know the trend of their individual stocks. .

8：。 You can buy and look at various indicators, understand finance, insurance and various stocks in combination with the current situation, and then analyze and understand the stock market.
