rebalance between asx200 and asx300

I was doing some interesting reading and found this:

"In new research, Macquarie Equities reckons that in the case of the ASX200, stocks in the past have run up strongly up to the inclusion date but then underperformed in the period thereafter.

However in the last five rebalances, the pattern has changed: stocks have run hard leading up to the announcement of the changes (ten days before implementation date), but then underperformed into the implementation.

In the case of the ASX200 deletions, they underperformed leading up to the announcement, traded flat during the implementation and then rebounded post-implementation."



I thought the latest rebalance was meant to occur last Friday but I am yet to hear or read anything on MAD.
