Taking into account risk capacity and the ability to study from where this guy is from, I still down think it's achievable. What you say is true, however the stock you choose largely depends on the risk your willing to take. If you are looking for capital growth, your generally looking for companies focused on innovation, like the CSIRO, or other companies that have a certain type of business model (I dont remember the name, but a stock that benefited it was called CSL limited, search it up on the ASX).
Also in AU our economy is kinda fucked, bit the ASX is doing real well. I think it's mainly about people ditching these low yield term deposit and transcending th capital structure in search for higher yield. In this day an age, conservative investments are dead.
