Buy and hold strategy vs CPPI vs Constant mix

In the question, investor recommend to add more position when market goes up and sell the position when market goes down. This objective clearly is in line with CPPI. However, investment advisor expects market to become Ocsillating a in coming days, which suggests constant mix is the best choice. Can you please give me your opinion, if I miss somethings.

Constant mix sounds best if the advisor’s expectations prove true.

Is there some reason to believe that the investor has better insight than the advisor? Or vice-versa?

Dear Magician,

Thanks a lot.

Can you please tell me if advisor wants to achieve investor’s objective as well, which strategy will be the preferred one?

Thanks
