Under normal circumstances, after buying 1, yuan according to your idea, it will be halved to 5, yuan. ? At this time, the 5% increase is based on the increase of 5 yuan. Therefore, the current principal is 5*(1+5)=75 yuan

This is just a general statement. Under normal circumstances, fund stocks have ups and downs, which means that no matter whether they are up or down, they will not exceed 1%. That is to say, your assumption is not true.

unless it is falling continuously.

but if you have analyzed and valued such fund stocks, it is an opportunity to fall now.

no one will buy a fund at one time, and the correct way to open it is to make a fixed investment every month.

If you can, increase your position when it falls, and make a grid line. For example, at present, the fund of the fund is 1 yuan, and how much will you buy when it falls by 1% or 5%.

when it goes up later, your cost has already been diluted. For example, now the cost is 1 yuan. If you buy 1 at 7 yuan, the cost will be 8.5 yuan. If it goes up to 13 yuan, the difference will be 4.5 yuan.

this is just a simple example. the floor is based on 1 shares, and the cost is 1 yuan. 1 shares is 1 yuan, which means that you can buy 1 shares directly and it is 1 thousand yuan.

if you buy 1, shares for 7 yuan, your actual principal is only 17, yuan, your cost is 8.5 yuan, and your position is 2, shares.

if it's 13 yuan, it's 26, yuan, and the income is 9, yuan.

off-site, you need to divide 1 by the unit net value of the day, and the rest is your share. The unit net value is the price of the off-site fund. The less the unit net value, the more the share.

What is the unit net value at that time when the unit is sold? Excluding the cost, the price difference * share is your profit.

I haven't bought a fund off-site, so it would be easier on-site.

the conversion is basically as I said above.

this is true for both fund stocks.

But the stock is different because it can't make a fixed investment every month like a fund. If you don't make a grid line, you can make a fixed investment every month. This fixed investment can be determined by the valuation space and price of this fund at that time to dilute the cost.

the above is the answer to your question, please accept it if you are satisfied ~
