Why would you do that, unless there is insurance in it?
Performance of ANY super fund is an equation of investment returns less fees (which generally aren't really too much different to each other except a few older ones). If you aren't happy with the SMSF returns then change to investment strategy to be similar to the old retail one and you'll get more or less a similar result. If it's in a share (index) fund, both will rise / fall reasonably similar amounts whether a managed fund or an ETO (note: this is not an invitation for any other posters to have a whinge about <0.5% differences in fees between these options - get back in your box now!). If it's in a 'Balanced" fund then a similar wholesale Balanced fund in your SMSF should return a similar amount -although there can be a wide range of variables there, if you want cash - go with cash.
The point is that your selection in the old fund is as relevant as your SMSF, you can duplicate similar. If your SMSF investment strategy isn't working, maybe default back to cash and rethink what you are doing or the markets or just do nothing for a while.
