DK /diː/ /keɪ/ (v.)
Saint Peter-style, to disown, deny, or feign ignorance. DK stands not, as the JC believed in some humiliating mondegreen until 2021, for “drop-kick”, but for “do not know”. To “DK” a trade “alleged” by an executing broker to a prime broker, is to refuse to take it, as is sometimes required by the SEC no-action letter.
