Rights Issues are executed within a given period that begins with the announcement of the issue and ends with the distribution of the shares to the eligible shareholders. You can find it on the company issuer's website or the company’s official exchange website.
If you qualify and subscribe to a rights issue within the subscription period, simply wait for the official share distribution to receive the newly issued shares in your account. The duration of this period can vary from 10 days to a month, depending on the specific terms of the issue. The announcement message will provide the exact timeframe.
