you asked a second question here which the people were responding to.
"Thanks for the reply nanood. with regards to #2, if I made 1000 profit and made 2000 loss. what happens with the 1000 extra loss?"
HOWEVER in the first example.
"1. Will a Capital Loss be incurred when; for example I hold 1000 shares in company ABC @ $1 each and then the following week I decide to sell 500 shares of the same company at $0.5 each? or is only a capital loss once I dispose of all the shares?"
500 * (1.00 -0.50) = $250 Capital loss
And you would still hold 500 shares where no loss has been made as they have not been sold.
