That if you are in the market for topping up on Aviva, that the best days to do so are when it has gone ex-dividend and particularly when the FTSE itself has trended down and not recovered as yet.
Good solid company with an assured strong and growing dividend each time.
In that way it lets you buy in on the cheap, so to speak, for the next one and you gain off any changing upward momentum in the FTSE100 should you not be prepared to hold firm.
