Does an auditor has a problem buying the stock of a company he or she audited after the audit is issued?

After the audit is issued, the auditor should be able to purchase stock in that company. However, since this person is privy to information that would be available otherwise to insiders only, he/she can be questioned by the SEC or IRS should there be any major movement in the stock soon after wards and they sell their stock at that time. The longer they hold the stock, the less likely can that person be considered using information illegally for personal gain. Hope this helps!
