Hey oxxa,

If I wana sell a few shares and hold onto some, will my 50% cgt for holding onto for a year start again or will it remain the same date as I first purchased them?

I've accumulated shares as its climbed aswell, how would the tax work on that if I held the first lot I purchased for over a year and sold some as I push my money elsewhere?

Any info will be appreciated..
