This rule is no longer applicable. NASD IM 3310 has been superseded by FINRA Rule 5210. Please consult the appropriate FINRA Rule.
A member, in the conduct of his business, shall observe high standards of commercial honor and just and equitable principles of trade.
No member shall publish or circulate, or cause to be published or circulated, any notice, circular, advertisement, newspaper article, investment service, or communication of any kind which purports to report any transaction as a purchase or sale of any security unless such member believes that such transaction was a bona fide purchase or sale of such security; or which purports to quote the bid price or asked price for any security, unless such member believes that such quotation represents a bona fide bid for, or offer of, such security. If nominal quotations are used or given, they shall be clearly stated or indicated to be only nominal quotations.
No member shall effect any transaction in, or induce the purchase or sale of, any security by means of any manipulative, deceptive or other fraudulent device or contrivance.
It would be inconsistent with the above provisions for a member to publish or circulate or cause to be published or circulated, by any means whatsoever, any report of any securities transaction or of any purchase or sale of any security unless such member knows or has reason to believe that such transaction was a bona fide transaction, purchase or sale.
Similarly, it would be inconsistent with the above provisions for a member, for itself or for any other person, to publish or circulate or to cause to be published or circulated, by any means whatsoever, any quotation for any security without having reasonable cause to believe that such quotation is a bona fide quotation, is not fictitious and is not published or circulated or caused to be published or circulated for any fraudulent, deceptive or manipulative purpose.
For the purposes of this interpretation, the term "quotation" shall include any bid or offer or any formula, such as "bid wanted" or "offer wanted," designed to induce any person to make or submit any bid or offer.
