Recency Bias Meaning

Recency bias is a psychological phenomenon where an individual gives significantly more weight to recent events than to historical data when making decisions. In investing, this often manifests as a belief that the current market trend (whether bullish or bearish) will continue indefinitely.

It is one of the most common reasons retail investors "buy the top" and "sell the bottom."From a cognitive standpoint, this is a mental heuristic that the brain uses to process information quickly. During a crypto bull run, the daily "green candles" create a feedback loop where investors forget about past crashes and assume the asset will go to infinity.

This leads to emotional trading and a failure to set "Stop Losses," as the brain is tricked into thinking the recent success is the only possible outcome.To combat this, professional traders use "Systematic Trading" and historical backtesting. By looking at data over 5 or 10 years, they can see that markets move in cycles and that extreme growth is almost always followed by a correction.

Fintech apps are starting to incorporate "Behavioral Nudges," like showing a user their "All-Time" performance rather than just the last 24 hours, to provide the perspective needed to make rational decisions.
