First of all, if you feel that the income has been fully satisfied, you can reduce your position moderately instead of selling it at one time. If it still goes up in the later period, then you can continue to sell in batches, so that it will not be empty because of a decision.

Secondly, I can provide you with more objective decision-making methods.

First of all, you should know the fund you bought. What kind of investment target does it belong to? Is it a big blue chip or a small and medium-sized enterprise growth stock? After you figure it out, you can go to CSI official website to check the rolling P/E ratios of CSI 300 and CSI 500.

For example, the current P/E ratio of CSI 300 is 15 times, while CSI 500 is 32 times.

Divide 1 by the price-earnings ratio, and you can get the return on investment of the relevant target. Simply calculate, the current investment yield of CSI 300 is around 6.7%. The return on investment of CSI 500 is about 3. 1%.

Then compare this rate of return with the risk-free investment rate that can be obtained. Generally speaking, the reference object can use the annualized rate of return of Yu 'ebao, which is currently about 3.9 1%, but it should be noted that the annualized rate of return of Yu 'ebao is not stable. Or the yield of ten-year treasury bonds, which is currently 3.74%, is also fluctuating.

Divide the return on investment of stocks by the return on risk-free investment to get a ratio. If the fund invests in blue chips, if the ratio is higher than 1, then holding the fund is still the first choice. If it is a small and medium-sized fund, because its target has certain growth, I personally think that the ratio is at least higher than 0.5, which is worth holding.

So now, stocks are still a product worth investing in.

Of course, there are two points to note. First, your money is not urgent, you can hold it at any time. Second, the P/E ratio and risk-free investment yield are unstable and will change, so we should always pay attention to them.
