Growing super, surely shouldn't matter what asset class you chose, as long as you are happy with the return, right? Perhaps you are seeking diversification from property, so you like managed funds, or lack the experience to invest directly into shares (another option).
I really dislike the comment that too many people are putting money into property in their SMSF? What do you mean, the statistic is that around 3.5% of SMSF have leveraged into residential property, but yes commercial is much more invested as many would involve their businesses there.
Yet most, I think at least of 60% of people's super is invested in stocks, yet no one is worried there? So I do not understand there reasoning for concern there?
Anyway best of luck in your investing......
Diversification is but one fundamental element of the long term investment plan, risk management, liquidity/accessibility of the funds are two others.
Higher returns means greater exposure to risk ie. Equities, lower returns are linked to low risk investments eg cash at bank, government bonds etc. The trade offs are security and liquidity ie you can get easy access as opposed to trying to cash out of a CIP or RIP if you require ready access to cash in the smsf eg if a member dies and the fund is forced to sell as a reluctant vendor in order to satisfy the demands on the assets. Shares can provide greater returns than cash with greater risk however are much easier to sell (@ lower transaction cost) than a direct investment in property seen as low risk but low liquidity.
