Thanks to all posters who provide information on CMF.

Here, I compare the two CMFs.
RHB Cash Management Fund 2
- Interest Rate: 3.35% per annum
- Withdrawal takes 2 days and can only be done on Mon-Fri (have to put in sell order by 3pm).
- NAV increases on a daily basis. So, upon withdrawal, principal and interest can be obtained at the same time, 2 days later.
Phillip Master Money Market Fund
- Interest Rate: 3.49% per annum.
- can withdraw at T+0 (fund credited by afternoon same day to Maybank account if redeem before 930am).
- Interest is only credited once, at the beginning of next month. So, upon withdrawal, only principal can be obtained at the same time.
Another downside is that for Phillip Master Money Market Fund, since we receive the interest late, we cannot compound the interest, by reinvesting the interest. This is particularly true, if we choose to withdraw our principal early of the month, and have to wait for the interest to be credited next month.
