In my opinion, people have made massive gains on FDC and lost a load on other stocks. coming to EOFY I think people may be taking opportunity to offset their losses with gains and balance books. not my style - I have held since the dark days and still believe the company has strength moving forward in the medium term. between now and mid july we will see some wild swings.
The down days are on lowish volume also.
Also divies are attractive.
