Asset allocation

7 minute read · By Krishna Avadhani, Vestora Academy · Updated 18 October 2026

Asset allocation is how you split money between shares, bonds, property, cash and alternatives. A widely cited 1986 study by Brinson, Hood and Beebower found that allocation policy explained over 90% of the variation in a pension fund's returns over time, far more than stock picking or timing.

Typical diversified mixes range from conservative (around 30% growth assets) to high growth (around 90%+). Australian super funds publish their mixes, and the Vestora Plan tab lets you test them.

The right mix depends on your time horizon, need for income, other assets (a secure job or pension acts like a bond) and how you will behave in a crash. A mix you can stick with beats a "better" one you abandon at the bottom.

Key takeaways

  • Allocation drives most of the variation in portfolio returns.
  • Your job and pension count as part of your allocation.
  • The best mix is one you will hold through a crash.
