You will be able to adjust the short-term losses against your gains. However, there’s a provision under the Income Tax Act that disallows bonus stripping. Under this section if,
An investor buys shares within a period of 3 months prior to the record date of the bonus issue AND,
The investor sells all or any of the original shares within a period of 9 months after the record date of the bonus issue.
If both the above conditions are fulfilled, you’ll not be able to claim the losses.
