Well...
you can write off share losses against other income if you run a business of share trading and the net result in the business is a loss (assuming you meet the claimable loss rules and the business is in the same entity as your other income) because they become tax losses instead.

but yes if it’s a simple investor they are still capital losses and will just carry forward until offset against other capital gains.
