I think so...under the cricumstances.
During October total volume was 67m shares. So Patersons dumping 9.9m (sold 9.9m + buying back 2.2m) is more 14.7% of the total turnover in that time.
There were 1432 trades in Oct. According to the numbers my broker from IRESS, Pattos were responsible for 227 of them - 16%
