Suppose 2.484 (closing price) buys 10000 B funds,

Step 1: After closing the position, the market value of your position is calculated according to the net value, that is, from 24,840 yuan to 22 105 yuan, which is your current B fund equity.

Step 2: After the discount, the net value of the parent fund and AB fund will be restored to 1 yuan. At this time, your shareholding will become 1 0,000 b, 1 2 1 0,005 parent funds.

Step 3: Split, suspend trading next Monday, and start trading next Tuesday 10: 30. At this time, if it is split, it holds 10000+6052= 16052 copies of B (decimal is not considered for the time being, the fund company will be accurate to decimal, and decimal is not calculated here) and 6052 copies of A base.

At this time, because it is impossible to predict the opening price of next week, you can use Friday's closing price to calculate the floating profit and loss.

16502 *1+6052 * 0.914 = 22033.5 yuan. In other words, if you participate in the discount, you will lose 24840-22033.5 yuan, that is, 2806.5 yuan. This does not include the situation that the A fund will not plummet on the day of resumption of trading, because everyone wants to protect B and sell A, which will definitely lead to a certain decline in the A fund.

At this time, if fund A does not lose money or make money, and fund B wants to make a profit, it should be at least 2806.5/ 16502= 17%.

Considering the possible decline of Fund A, it will take at least 2 daily limit to return to the capital.

The reason for expanding the data is that when we designed it, B borrowed money from A, and at the same time ensured that B would lose money first. When the market is getting weaker and weaker, most of them are in the net value of 0.25, so they must be converted to ensure that they will not lose a when they continue to fall. One problem at this time is that if you don't sell it before the discount;

Because the price of B in the transaction is generally higher than the real net value, and it is converted according to the net value after the conversion, then if you ignore other issues such as the rise and fall after the opening, you will lose a premium first, which is a real loss.

In last year's decline, many investors should have felt the leverage of this graded fund, and even many investors did not understand this leverage. Therefore, the regulatory authorities have now raised the investment threshold for classified fund transactions, which is also a good protection for investors.
