FT Russell Reconstitution, page-6

It is usual for SP to rise as Index funds etc need to hold constituent stocks. While those major institutions will hold those stocks (due to their mandates), they sometimes are not prepared to pay the going rate at inclusion date.
This happened with a number of stocks when the latest ASX 200 rebalance came out, a couple of stocks I hold have fallen significantly ( I reckon dodgy trading practices ), that was before this latest market correction, SO I HOPE this drop in 5EA SP is purely related to the correction and not manipulative strategies to gain a holding at a lower entry to satisfy their mandate.
I'm keen to hear others views why 5EA is being crunched at the moment. It does go for some volatile runs. I'm hoping for a usual recovery to ~$3.30s, but one part of me wants to add more to my holding. I'm just concerned that I probably have enough risk in what I have. (Having written the above, I think I have answered my own question!).
I hope SP gets less volatile once we recover.
