Can you write call options with your Self Managed super funds?

Is anyone doing their SMSF successfully on the ASX? We have had our 100K tied up by financial advisors for long enough and reckon we could do better!

Yes there is no issue for a SMSF to write call options. You can argue that you write the call options as a hedging strategy for your other investments. You are in fact protecting the fund's investments. If you want to go down this path, you need to ensure that the fund's investment strategy reflects this.
If you continuously trade options, one might argue that the fund cannot do that as a SMSF cannot run a business. Note, the legislation actually does not say that an SMSF cannot run a business. The Commissioner does not say that either.
What the Commissioner says is this - when a Superfund starts running a business, it would be rather hard to argue that the Superfund is still all there for the Sole Purpose test. And as you're aware, the Sole Purpose Test is a must.
So, as long as the Superfund is still there for the Sole Purpose Test, provision of retirement fund, there is no breach and it is ok.
Therefore, you need to weigh up frequency, dollar amount etc.
I can't comment about the investments side of SMSF. I'm not a registered financial planner.

Well probably best to change advisors (guessing your with some hobo at a bank), due to the leveraging of options you cannot write call options with your SMSF you can however use Self Funding Instalment Warrants to unlock equity within your existing portoflio. Try www.ofp.net.au they have lots of fact sheets and the guys there seem to be really really switched on.
