4 the dummies

end of financial year
lets say i am a huge supporter of awe and want to stay in
BUT
i bought at 2.80 a year ago or what ever - haven't checked the chart.
but last day trading i sell at3.70
capital gain90c on say 100000=$90000
BUT
i only pay tax on $45000
I get back in on monday @ around 3.70
having saved heaps on tax as i think this stock will do the same next yead
ATO thanks for comming
