The reason for this problem is simple. The reason is simple. Most people will only notice a fund after it rises. When the fund has not started to rise or is unknown, no one will care at all. This fund usually gets the most attention after the fund rises sharply. At this time, the performance ranking of the fund will be higher, and the foundation with the highest performance will be more displayed. In other words, it will be noticed by more and more people, but the stock market will not only rise but also fall. When the market rises more, the market may adjust. Therefore, if the current fund is soaring, or because the current fund is popular, chasing the fund for the above two reasons is more likely to cause losses after buying the fund and starting to fall. Warren Buffett, an American investment celebrity, has a famous saying: others are afraid of my greed, others are afraid of my greed, and I am afraid that the market is anti-human, and all the money I can see is not profitable.
