FUD

Quick definition

Fear, Uncertainty and Doubt — negative news or rumors that spook the market.

FUD covers scary headlines, rumors and doom-posting that push people to panic-sell. Some FUD reflects real risks; plenty is exaggerated, recycled or spread deliberately to move prices.

The skill is separating signal from noise: check the original source, the date, and whether anything actually changed. Reacting to every scary headline is as costly as chasing every pump.
