Fundamentally, if you want something "safe" then in my opinion you want something which is at least exposed to
different risks to that of your "growth" funds.
I am assuming that your "growth" funds are to be used for long positions in shares that you select. Therefore, if it were me, I would be looking at:
(Note that specific stocks and accounts mentioned are for example only and are not intended as a recommendation. All my posts are my opinion only and are not investment advice etc.)
(listed in no particular order)
Cash - At call (ING or similar)
Term Deposits - but only if the interest rate outlook is favourable compared to holding cash at call.
Bonds - Via a managed fund if you don't want to be directly involved in bonds.
Listed property - Or a managed fund investing in it.
Managed share funds.
Commodities - Probably by means of buying and holding the major producers such as BHP, Rio Tinto, Woodside Petroleum etc. Speculative mining stocks do not fit into this category - if you trade them then they belong in the "growth" portfolio IMO.
Precious metals - physical gold and/or silver. Also the stocks of mining companies such as Newcrest (gold) or Macmin (Silver). Note that Macmin is somewhat speculative and that silver stocks in general are few and far between (most silver produced is a byproduct of other minerals) so there's not much to choose from with silver. Can still have a place in investment though.
Foreign currencies - actual deposits in major currencies such as US Dollars, Euro, Yen etc. as opposed to leveraged forex trading which is a "high risk" strategy which IMO shouldn't involve "safe" funds.
Hedge funds - Also called "absolute return funds". Personally I wouldn't put too much in but there could be a place for investing in these via a managed fund which spreads the risk across lots of different hedge funds. A "fund of funds" if you like.
IMO all of these have their merits but there are some that you wouldn't want to put too much into. You ought to look at all of them though and understand what is involved even if you decide that they're not for you.
At various points in time you would have gained or lost significantly by holding each of these asset classes (cash losses are due to inflation). You could also have made $$$ trading them (except cash and hedge funds which are generally impractical to trade).
Make sure you understand these asset classes before you decide in which to invest. Don't assume that just becasue something lost over the past 5 years that it will always lose or vice versa. And spread the risk.
