Fund managers may not always act in the best interest of their clients due to how they are paid. When managers receive performance bonuses, they may be more focused on making money for themselves rather than their clients. This can lead to a conflict of interest when it comes to dealing with sudden jumps in the stock market. Managers might take on more risk than their clients are comfortable with, especially if they are only in their position for a short time. To address this issue, regulators should consider charging fund managers a fee when their performance is very poor to prevent them from making risky investment decisions.
