none in particular, just that the shorts were net buyers over 10-12 May therefore the share price collapse was caused by longs selling.
As you can tell from the broker data, it appears that most of the net buying came from retail houses - commsec, ausiex, etrade, weathhub etc whilst the selling came from the insto houses - Citi, Deutsche, Instinet, GS and MS

the one outlier among those is CS who were net buyers of 4.3m shares - almost certainly short covering.
