Not sure if your interpretation of the rules is entirely correct @boney35 - the 50% of 80% for NDQ - coz I've previous been with AustralianSuper and I'm now with CBUS, another industry super fund that has the same rules but a slightly smaller investable universe than AustralianSuper who have more ETFs and LICs on their "menu".
The 80% rule applies at the time you place a purchase order (a buy), but is not enforced between buys, and the individual position weighting rules - so 50% in the case of NDQ - do apply to your entire super balance, not just to the 80% you can invest in through their "Member Direct" option.
For example:
- Bob has $500,000 in his AustralianSuper account (his withdrawal balance).
- Bob can sign up for AS' Member Direct option and transfer $400 K into Member Direct (80% of the $500 K balance).
- Bob can then invest $250 K (half of his $500 K balance) in NDQ.
- Bob now has $150 K left in Member Direct that can be used to invest in ASX300 companies or any LICs or ETFs that are on AustralianSuper's "approved" list (their investment menu).
So Bob can't invest 50% of his super balance into NDQ AND invest the other 50% in something else, but he could invest 50% in NDQ and 30% in something else, as long as Bob leaves 20% in AS' managed strategies, such as High Growth, Conservative, etc.
The individual weighting limit rules (such as 50% for NDQ and 20% for ASX300 companies) are also only applied at the point of purchase, i.e. when you place a buy, and the position can grow as large as it likes after that.
But my understanding is that you could invest 50% in NDQ, just not 50% in something else at the same time, coz you'd only have 30% left in the Member Direct portion of your super.
This understanding is based on my own experience of being able to invest 20% of my entire balance in an ASX300 company, which I have done on multiple occasions.
