Under the DFM's Professional Code of Conduct, a broker must wait to publish verified information...

The DFM Professional Code of Conduct imposes a specific restriction on brokerage firms concerning market data and information about entities whose securities are listed on the exchange. A brokerage firm must not publish or promote market data or information concerning the status of a listed entity unless the information has first been verified and made public by the concerned entity . This prevents brokers from distributing unconfirmed, selective or prematurely disclosed information that might influence prices or create information asymmetry between investors. The rule complements broader DFM obligations requiring brokerage firms to act honestly and fairly and to avoid misleading conduct. The broker does not need a separate publication approval from the Authority for every item falling within this rule. Signing a conflict-of-interest disclaimer does not convert unpublished information into permissible market data, and assessing the information's potential impact is not the regulatory trigger allowing publication. The decisive condition is that the information has been verified and publicly disclosed by the entity concerned. Accordingly, option B is correct.
