As a fund manager, it is terrible that the average annual income is negative and the negative income reaches -33%, so it is better not to consider it. Of course, if the working hours of fund managers are relatively short, such as only one or two years, it is even better. After all, short working hours and limited experience can be forgiven. If the fund manager has worked for more than three years and the average annual income of the fund he is responsible for is negative, it can basically prove that the fund manager's investment ability is average, and his fund should be carefully considered. You know, as a fund manager, he is not fighting alone. Behind every fund manager, there is a relatively large or professional investment research team, which is responsible for doing on-site research and data analysis for him, and then he makes decisions, what industries and stocks to buy, or what investments to make, and so on. Under such circumstances, he can lose so much weight on average in a year. What can explain the problem? There is only one answer, poor ability.
