Assuming that this is just a small part of your diversified portfolio - why not just keep them and enjoy the capital gain and the next outrageous divvi in April?
However - if you did violate your undoubtedly thoughtful policy on diversification, than now (after the good AGM news) might be a good time to reduce - but who am I to know?
Discl: hold (a small parcel) and don't intend to change that for now.
