Same risk applied if you put 10 times money into BHP/Telstra/CBA and the reward is lower.
Depends on how much FA you did, AVB used to be a great investment last year if you read the ann correctly: NPV enterprises value exceed 14cps by my calculation for its very rich copper project.
It still has lots of potentials here depends on the pending assay due the EOY, but the downside risk is becoming too big: it's done for me.
