Mmmm ye I have seen this in ESOR (up and down from 18c to 23c) and in ENX specifically, was at 250 then trickled down to 220, and suddenly 600k volumes, where previously it was 2k, 5k, and 10k purchases.
Just seems strange to me, and my only conclusion is that it get sold in 2k, 3k and 10k batches, forcing down the price to specific price point and then BAM in comes the volume.
I mean at 220 per share selling 315 shares = R693.00, and then the buyer has to pay all the tax etc., strange
