Eleven Dragon,

ASM is Amanah Saham Malaysia, this fund have no limit per person to buy units, subject to fund size, as long the fund size still able to capture the amounts, the size fund is depend by percentage of races. Majority holder will be given to Bumiputera 50%, 30% for Chinese and etc. units will be available if any current unit-holders sell off their units in exchange for ringgit. At the moment, it is always fully subscribed if you're saying about Chinese quota.  ASB is the fund which capped at 200,000 units, with unlimited fund size. It is good because it a capped price at the rate of 1 units per ringgit without fluctuation. For low risk taker, it is always a good investment while for smart investors, it is not a good investment since they can get a better rate of returns.

Eleven dragon,

Only ASB (Amanah Saham Bumiputera) is capped at 200,000 per adult unit holders, other relative fund have no limit, which mean you can buy all units as long there's available unit fund depend race quota.There's only a capped normally during initial offer period such as new fund or another fund increment but subject to the limit from time to time. After initial offer, normally they offer in whole lump sums where you can whatever left unit until the fund is fully subscribed within race quota. Let me give you an example, please download annual report as shown below and go for page 2, unit holder section (pegangan unit).
