Regulation SHO also created the "Threshold Security List", which reported any stock where more than 0.5% of a company's total outstanding shares failed delivery for five consecutive days. A number of companies have appeared on the list, including Krispy Kreme, Martha Stewart Omnimedia and Delta Air Lines. The Motley Fool, an investment website, observes that "when a stock appears on this list, it is like a red flag waving, stating 'something is wrong here!'" However, the SEC clarified that appearance on the threshold list "does not necessarily mean that there has been abusive naked short selling or any impermissible trading in the stock".
