Status Quo Bias

Also known as Inertia bias

Status quo bias is preferring an existing choice or allocation because it is current, even when alternatives may better meet objectives.

Why status quo bias matters

Inertia can leave portfolios unrebalanced, expensive, concentrated, or inconsistent with changed goals.

How it is applied

Investors use default reviews, scheduled rebalancing, fee comparisons, updated IPS constraints, and explicit reasons for retaining each holding.

Portfolio example

An employee keeps all retirement savings in a default fund long after risk and horizon change.

How to interpret it

Maintaining a position can be optimal, but should follow active review rather than inattention.

Limitations and common misconceptions

Frequent change also creates costs and behavioral mistakes. Good defaults can improve outcomes.
