Buy quality
Junk bonds and certain properties may pay a higher yield, but if they do the risk will be higher. The NZ Super Fund just lost $200 million investing in a Portuguese bank - a classic junk bond.
If in doubt, do half
This is one of the best rules. It can apply to buying or selling bonds, multiple rental properties, shares, loans to children, helping a wayward brother, and so on.
Average into investments over time
A logical extension of half now and half later. Once you have decided to invest, buy half now and half in six or 12 months (this is really easy to do with bonds and shares).
Diversify widely
Find out what this means and never forget it. Diversify onshore and offshore since the small New Zealand economy lacks diversity and is vulnerable to earthquakes and imported diseases.
Get experienced independent advice
There are few truly independent advisers - only about 300 New Zealand-wide.
Avoid investments that are not liquid
Very few investments nowadays offer any advantage by being locked in.
Liquid investments can double as emergency funds, so why not?
Do not allow fear or greed to influence your decisions
US research indicates the average DIY investor gets about half the return they should. It's thought they mainly fail by reacting to fear or greed and either selling out near the bottom when things look bad or buying near the top when things look good.
Ditch the rose-tinted glasses
Be disciplined. Be ruthless. Never fall in love with an investment. Look at both the pros and cons. If in doubt, write them down.
Make haste slowly.
