Hi everyone, I have a question regarding DCA and broker fees.
Lets say I got shares for companies A,B and C.

and now every month I buy shares like this:

A - RM300
B - RM400
C - RM200

so I pay rm21 broker fees per month

***********************************

Is it better if i do like this:

this month buy A - RM850
next month buy B - RM900
third month buy C - RM870

Three months only pay RM21 fee

On one hand, in the long run I would be saving a lot on the broker fees. But then wouldnt the effect of DCA for each share would be lesser because I buy from each company less often (once every 3 months)?

But also, given how volatile share prices can be, DCA may not be impacted as much anyway I suppose?
