Fear Uncrtainty and Doubt FUD FUD stands for “fear, uncertainty, and doubt” and refers to a general mindset of pessimism about a particular asset or market, as well as the manipulation of investor or consumer emotions so that they succumb to FUD.
While the term “fear, uncertainty, and doubt” has been in circulation for a century or so, it became popular as the abbreviation FUD in the 1970s — and widely known more recently, thanks to the highly volatile crypto markets. FUD is also used throughout finance and can apply to any asset class.
