I routinely break the golden egg-distribution rule: they're all sitting in one chicken-shaped basket right now, on the top shelf in the kitchen.
But the cliché is normally rolled out as an investment metaphor rather than a practical egg risk-management strategy. The diversification message is clear enough: don't stick all your money in the same place.
In practice, diversification just means spreading investments across asset classes (such as shares, bonds, cash and property) according to taste.
However, should the same investment manager be holding all the baskets? Typically, investors hire a range of fund managers to handle different asset classes - or a multi-manager to make those decisions on their behalf.
Recently, though, the new concept of single manager 'multi-asset' investing has gained popularity. As this 2010 article from a US website shows, the "buzz phrase" isn't really that new - but it is fresh to NZ.
