Recency bias

Trader's Glossary · Psychology

Recency bias

Definition. The tendency to give too much weight to the most recent events compared with the longer history.

How it works

The latest sessions are the most vivid in memory, so it's easy to assume the market will “always” behave that way. It's a variant of the availability heuristic described by Tversky and Kahneman.

Example

After a few quiet days a trader underestimates the risk of a sharp move on the day of an important data release.

What to watch out for

What helps: regularly reviewing a longer history in your journal and statistics from many sessions.
