Hi Nomad
The apparent inevitability that 'gaps get filled' (specifically shares, not rare minerals which may rise sharply in price never to return) seems to be accepted within the markets and there are numerous on-line articles about them and the different types.
I have come to accept that sp gap fills are very likely. However, I have found no mathematical explanation other than it seems to depend on the fact that no trades were conducted during a rapid price move, so there is little resistance or support present within that price band to prevent a reverse move. My view is that they only get filled if the price naturally returns sufficiently close to expose the weakness (lack of support/resistance) in that price range. I have seen fills that take years to occur (OCADO is a recent one that comes to mind).
Regarding timing: by 'after results' I meant 'after the current upward pressure has abated', which could well be after ex-div, always remembering that quarterly dividends don't have the same impact as annual ones.
