It's the broker data over the last month and last 6 months, respectively. I'm not on top of them all, but you can use the data to look at trends of who is buying and selling over periods. If you understand which brokers are predominantly retail, and which are on behalf of instos then you can see where the money is flowing.

To me it looks like money has been largely floating out of insto investment and into retail hands. This would generally be perceived as a negative as shows less interest from the 'pros' and more being held us average joes.
