Term of The Day: Lady Macbeth Strategy
A corporate-takeover strategy with which a third party poses
as a white knight to gain trust, but then turns around and joins
with unfriendly bidders.

Investopedia Says:
Lady Macbeth, one of Shakespeare’s most frightful and ambitious
characters, devises a cunning plan for her husband, the Scottish
general, to kill Duncan, the King of Scotland. The success of
Lady Macbeth’s scheme lies in her deceptive ability to appear
noble and virtuous, and thereby secure Duncan’s trust in the
Macbeths’ false loyalty.
