Just a quick follow up from my previous query. If 'Answer B' is correct than you might not get any CGT discount depending on how much in the way of losses you made.
Example:
Company A - Buy $10,000 worth and sell for $19,000 after 12 months (50% discount available).
Company B - Buy $10,000 and sell for $1,000.
I'm assuming the answer is $0, which in that case, it would have made no difference if you sold before or after the 12 month period?
