What would be a good or aggressive or safe approach when choosing options available in superannuation funds for next 4 months?
Superannuation (or any investing) is not something you should be measuring for the next 4 months, it's far too short a time frame.
No one in the world has any idea if markets will be up, down, left or right over the next four months.
If your time horizon for whatever is going on in your life at the moment is only 4 months, it's likely a cash option (where you have no chance of losing money) is your best option.
You really do need to talk to someone who can help you. Pay for some advice, you'll get all the answers & clarity you need. Doing it yourself by Googling things is not going to give you the answers to your specific situation.
My company has a partnership with an Investment company. We have a very good Investment option that i would be happy to talk you through and then put you in touch with them if you want to go forward with a SMSF and our product.
