I am assuming a Coalition win, perhaps a little premature.
I can think of a number of stocks, some of which I hold, and some I don't.
BHP. RIO. FMG. WPL. More certainty around mining/oil/gas in Australia.
SGH, MMS The former more litigation due to PS cuts, Union stoushes ; the latter more certainty over Salary Packaging
LLC, LEI More infrastructure spending.
History though, I am told, does not necessarily show a bullish trend post Australian elections.
