The ex date for the div is 15/3 so there is an incentive there for anyone with the necessary smarts to try and push the price down while accumulating.
Used to happen a lot with SAI when I held it.
Never understood what justification there can be for giving such a long trading period between the results and the record date. My opinion only is that it allows Directors to buy without the pressure of a high sp from the results. Note: Opinion only!
Don't think this is the only reason for the sp reaction but it certainly aligns the interests of those selling and those accumulating in keeping the price capped or at least from rising. Apart from announcement day the volumes aren't that significant.
