For anyone that might see this tomorrow morning (27/5/21) when the price changes.
C&C Group have announced a rights issue at 6/29 at 183p for existing holders in order to raise £151.1m.
From what I’ve been reading in these threads, Freetrade does not allow users to participate in this, more specifically they don’t allow.
That link isn’t very helpful its seems to be an issue of Freetrade not having an automated system to handle these events and there would be too many events to handle manually.
