How to treat the situation that listed companies entrust financial management with their own funds? Thank you. Excellent answers are rewarded with points:)

If listed companies have idle funds to entrust financial management, it is understandable to try to take lower risks and obtain higher returns. However, there is a problem here. If the main source of income of listed companies comes from this kind of entrusted financial management, it is extremely abnormal, so listed companies lacking stable main business should be vigilant. On the other hand, it also shows that the real economy lacks good investment opportunities and its operation is not very good.
