Has anyone looked into APT warrants provided by Citi? One strategy instead of profit taking could be to "extract cash" using warrants. Could pick a conservative option with e.g. 40% leverage, which would give you 40% of your holding in cash. The nice thing about it is it doesn't trigger a CGT event, and you can always put cash back in to convert back to standard shares.
@Karcus you look sound like you've been around the block, have you ever looked into this?
