As a fund manager, can I change the stocks held by this fund at any time?

The fund manager can change the position of the fund at any time, but he doesn't really want to change it within 24 hours, and you can't change it when the market is closed, because the normal changes of OTC funds now are from 9: 00 am to 1 1: 30 pm to 1: 00 pm.

Active open-end funds themselves can change their own market stocks, because fund managers buy a lot of money from the fund market. He is more optimistic that our company's stock belongs to the partial stock hybrid fund, which can bring you higher returns and of course may also bring you higher losses. The fund manager of this active open-end fund has the authority to actively operate. He thinks that a company's stock has investment prospects, so he will increase the position of the company's stock. Conversely, if he feels that a company's stock is not good, he can put this feeling. In other words, why don't you need to explain so much?

This is why many people think that the fund is making money when they buy a fund, and they boast that the fund manager is losing money, saying that the fund manager is a vegetable dog, because ordinary fund investors don't know why the fund manager is doing this, and some people may wonder. That stock is making so much money now, why don't you buy it? The same type of stock in the same industry has earned 10%, and you are still losing money. What happened? Everyone can't understand it, and fund companies and fund managers usually don't explain it too much.

However, fund managers of passive index funds generally do not have the authority to operate actively. The index fund follows the index. For example, CSI 500 follows this index to reach the corresponding index trigger trading conditions. Fund managers don't manage the flow of funds too much, which depends on the market situation and has little to do with fund managers. In other words, if you buy this thing, you will lose money. That's your bad eye, not the operation of the fund manager.
