Capital Gains Tax

[CJ]

So you buy 6789 shares of XYZ on a particular date, reinvest in their DRP and acquire another 73 shares on another date at a different price, then subscribe to a rights issue on another date at a different price, some time later you sell 357 shares (at a loss), buy back another 900 shares at another date, then another company takes it over using a mixture of script and cash payment.

Now multiply that by however many shares in your portfolio. Is there an easy way around this or do we have to have to spend all day in front of a spreadsheet?

do you use LIFO, FIFO or weighted average?
