That is a misconception.
Agents do not manage the funds. They are not fund managers nor is it likely they monitor the fund performance all the time.
Those putting their money inside funds is based upon that trust and idea that the fund manager will probably know more than what they do since they have no clue.
I agree and disagree.
While you are 100% correct to say that fund managers manages funds, the adviser have the responsibility (whether written in black and white or not) to manage the clients' portfolio and allocation.
The fund managers DO NOT have the right OR the responsibility to switch funds for clients, do they?
And if you say that clients are suppose to do their own due diligence to decide on fund switching themselves, then why are agents selling ILPs to clients without investment knowledge and fails their CKA in the very 1st place? I know we can't (by right), but you can't deny the fact that many agents are doing it.
My conclusion is that fund managers manages the individual fund basket and select the stock (or bonds) to be placed in it, while the adviser manages the client's portfolio and timely advises the client what funds to switch into when the existing invested market is not doing well.
If the agent cant provide the necessary advice and the client don't understand their own investment, selling them ILPs is just selling them poison to harm their financial health.
