All SEC registered stocks can be suspended under 'questions about the adequacy and accuracy' of company information, including false news releases, unauthorized share issuances, stock promotions, whatever else the SEC may allege. The SEC will choose to either litigate against the company and its principals or let those stocks die on the Grey Market until the Admin Law Judges revokes the registrations and FINRA deletes the ticker symbol. Although the losses are about 80% right after a suspension, most losses are eventually 100%.
Pinky Investors should always presume their desired 'OTC blue chip stock' is really a HIGH RISK SCAM designed to fleece investors, eg., false news releases to facilitate extreme dilution from toxic financings, nasty reverse splits, and consequent SEC Suspensions.
