If you buy today, it will go up today, then the price you buy is today's closing price, and it has also gone up. Whether the future will be good or not depends on the future performance of the fund. Part of the performance of the fund depends on the trend of the securities market. If it is an upward trend, it will go up for a while, which is good. If it is a rebound of the downward trend, even if it goes up today, the future is not good.
