Thinking about it a bit more I suspect that it might have been related to COK being dropped out of the ASX300 index. There has been steady selling on reasonable volumes for a few days that happen to coincide with the change to the indexes.
On Monday we will know as I would expect the big sellers to disappear if it was an index re-balance. If it keeps getting pushed down them I am wrong.
If I find a bit of spare time I might see whether other stocks being dropped from the index saw similar selling pressure recently
