Maybank stocks vs ASM/ASB-style funds for long term investing in Malaysia?

Hi everyone, looking for some opinions from people who are more experienced with long term investing in Malaysia.

I’m 24M, earning around RM4.5k per month, and I’m able to consistently set aside about RM1k - 2k monthly for long term investment. For now, I’m not really planning to go into things like gold or ETFs because I feel my current earning power is still limited, so I’m trying to keep things simple and realistic.

Recently, I’ve been consistently buying Maybank shares through MooMoo, mostly odd lots(or just one lot when I feel like it), because I like the idea of slowly building a position in a Malaysian blue chip and I’m okay with a long term approach. I also have some basic investing knowledge, so I’m not totally new, but still definitely learning.

At the same time, I recently opened an ASNB account, and now I’m wondering whether it makes more sense to start putting money into ASM as well, or just stay focused on accumulating Malaysian blue chip stocks like Maybank.

So I guess my question is:

Would you diversify between Maybank stocks and ASM, or just focus on one first?
For someone in my position, does it make more sense to split the RM1k monthly, or concentrate on building one portfolio properly before diversifying?

Would really appreciate hearing how you’d think about this from a risk, return, and simplicity point of view. Thanks.
