Understanding Rights Issues27 Oct 2020 16:57
I've written an article on understanding rights issues which will hopefully help.
The stock goes ex-rights at the close tomorrow. The share price will then gap down to factor in the rights, the same way a stock drops when it goes ex-dividend.

Note: If you are long with a spread bet or CFD account then do make sure your broker pays out the lapsed rights. They are yours and not theirs to keep.
