Recency Bias
Recency bias gives recent events excessive weight when assessing a broader body of evidence. In trading, it may mean judging a strategy only by its last few outcomes. New information can matter; the bias lies in unjustifiably discounting other observations, not merely in considering current evidence.
Illustrative example
How does it work in practice?
Suppose a journal contains 100 trades with three losses at the end. A trader declares the whole plan ineffective after reviewing only those three. Rule changes require assessing the full sample and possible changes in conditions.
A case to work through
Segment and whole
A fictional journal contains 80 trades with the last five separately marked.
- Assess the whole set and latest segment using matching measures.
- Check whether instruments, costs or rules changed.
What follows? Do not revise the plan solely around memorable entries.
Example boundary: No size of this illustrative sample guarantees a correct conclusion.
A useful distinction
Recency Bias / Overconfidence Bias
Overconfidence overestimates personal judgment; recency bias overweights recent observations.
