RE:Odd coincidence ? The quality of the information contained in these reports is poor. It would be less dangerous to abandon its publication than to rely on it. IROC's responsibility is limited to publishing these reports, without regard to content, as indicated in the regulations.
Short selling generates significant revenue and hedge funds collude with complacent brokerages, failing to report information to authorities. If brokerages do not default on the trade settlement date, the authorities do nothing. To ensure that the regulations are respected, and to identify the culprits, the efforts to be invested would be too great.
Hedge fund activity grew from 2005-2010, becoming a saturated market. The average yield is ever more uniform, and good yields ever more difficult to obtain. Consequently, they do not hesitate to break a few rules to achieve their goal.
That said, tracking these reports has become a waste of time.
