ASIC Investigation

This may have been covered previously but was wondering how ASIC initiates review of a company's financials? Presume they don't have the time to go through each company's financial accounts to identify issues. Is it mainly through complaints from individuals, funds etc?

Got me thinking about SGH. What if complaints were lodged one every few months so as to prolong conclusion of investigations? This would mean the ASIC would not be able to conclude inquiries until the final matter was resolved. Do you believe the organisations linked with short sellers are using this strategy with SGH to continuously drive down prices (albeit SGH seems to have contributed to lack of confidence with AGM annoucements).
