Investing wisely generates income and capital growth, creating wealth over time. Investing is different from saving.
Saving involves little to no risk, but the returns on your savings is low.
Investing can involve greater risk but should result in greater returns. A good portfolio will also reduce risk and minimise the chance of loss, but whatever happens, the amount of risk and investment volatility is set by you.
How you invest and the tax structures and strategies you use, either in your name, via a company, trust or through your superannuation, is just as important as the underlying investment selection.
