Typically the rule of thumb when investing is if you have a short time frame and/or want to ensure you don't lose money, you use a fixed interest type product, i.e. a product that has a defined interest rate and/or a defined time frame. If you have a longer time frame, 3-5 years generally speaking, you can afford to take on more risk.
Research shows us that over the long period the sharemarket (equity managed funds) will outperform other investment options. However, it also has the most volatility (movement in prices). The risk in a short time frame of 6 months is that the value of a managed fund may go down.
It's interesting to see those in the competition are using managed funds and choosing to take that extra risk. My thoughts are either they are having a play because its not their own money or that may be they don't understand the risk they are taking.
I would be interested to hear anyone's views.
