Asking this question shows that you don't know much about investment. Fund is essentially a portfolio, which can be used to invest in stocks, bonds, futures and so on. And indirectly invest in other investment products.

The rise and fall of the fund depends entirely on his investment in Changbai's shop. For example, your fund invests in the stock market, and the main heavy positions are military enterprises and the white glue period. In a short period of time, if the stocks he invests in rise, your fund will also benefit from it. If the object of his investment suffers a big loss, your genes will also lose money.

Therefore, whether the fund itself is the president depends entirely on the object of his investment.

Of course, some active funds and fund managers will take the initiative to intervene. They will choose to do some short-term operations and change their positions, which is particularly obvious in small private equity funds. If the fund manager's investment level is high enough, he can inhale on dips and sell on rallies.
