Since chatting with FP in another forum, I've changed my strategy. I've been investing in LPTs and shares whose value is close to NTA, where their revenue is related to the property they hold. I have a few other rules, such as they must have an OK div % return and consistent growth. I have a few exceptions to this, where I think there are exceptionally strong companies (monopolies) and I also trade (rather than invest) in companies that fluctuate due to economic or company specific winds.

I'm currently working towards making my portfolio look like this:

Invest in LPTs, VHP, SUM, POT, AIA, with a preference for the non LPTs
Small holding in IFT, TME, SPK, ANZ, SCL, SEK, MMH, SPN, RBD, ANZ and WBC

I also have a $10k fund for "fun", profits from which get invested.
