The answer is simple: there are too many fixed investment periods, and the average investment cost is "passive".

For example, the cost of the first fixed investment is 10 yuan, and the second is 6 yuan, so the average cost is 8 yuan, and the average cost is well shared.

If 100 has been fixed, the average cost of the first phase 100 is 10 yuan, and the cost of the first phase 10 1 6 yuan, then the final average cost is (100 */kloc-

This is the average cost of "passivation" of fixed investment.

It means that due to too many fixed investment periods, the latest fixed investment has little impact on the whole fund investment, and the fixed investment has lost the advantage of "diluting the unit cost in market fluctuations".

Huatai Securities found through calculation that after the fixed investment 1000, the average cost chart of the fixed investment strategy is basically consistent with the trend of the fund's net value, which reflects this "passivation" phenomenon.

During the 20 fixed investment periods,

It's best to split the cost equally.

In this case, how long is the right time to vote?

According to the research of Huatai Securities, if the number of fixed investment periods is 20 or less, the average investment cost can be well reduced. After 20 periods, the average investment cost tends to be stable.

Therefore, from the perspective of cost sharing, if it is a monthly fixed investment, then it is best to invest for 2 years.

But pay attention! It does not mean that you can get the highest rate of return after two years of fixed investment.

The final rate of return of the fixed investment of the fund depends on the market situation after the fixed investment.

It is also a two-year fixed investment, one is a bear market that falls unilaterally, and the other is a bull market that rises unilaterally. The income situation is definitely different.

In addition, we cannot predict whether the market will go up or down in the future.

Perhaps the yield of fixed investment has reached 50%, which is higher than ever, but it does not rule out the possibility that the market will continue to improve and the income will reach a new high.

Therefore, it is unrealistic to pursue the so-called "best fixed investment income effect".

A more practical method is to set a profit-taking line. After the fund's fixed investment yield reaches the profit-taking line, it will choose redemption (one redemption or partial redemption) and then start a new round of fixed investment.

Ok ~ to sum up the main points of today's article:

1, the fixed investment of the fund is not fixed investment, the longer the better. If the fixed investment period is too long, the average investment cost will be "passivated", and it is difficult to take advantage of cost sharing.

2. If the number of fixed investment periods is 20 or less, fixed investment can well reduce the average investment cost.

3. The specific rate of return of the fund's fixed investment depends more on the market situation after the fixed investment than on the fixed investment time. It is unrealistic to want to get the "best fund investment effect". The correct way to open it is to set a profit-taking line-redeem it after reaching the profit-taking line-and start a new round of investment.

In fact, we still have a choice, that is, choose a fund with excellent long-term performance, buy it in batches in the early stage by fixed investment until the planned investment amount is reached, then stop fixed investment and choose to hold it for a long time.
