Client Psychology and Behavioral Finance
Two different risk ideas
Separate risk tolerance (willingness, emotional) from risk capacity (ability, financial). A client with high tolerance but low capacity - concentrated employer stock, near-term liquidity need - must be constrained by capacity. Exam questions routinely offer an answer that honors tolerance while blowing through capacity; it is wrong.
Biases worth naming
Know the standard catalog and, more importantly, the corrective: loss aversion (losses hurt roughly twice as much as equivalent gains please, per prospect theory), anchoring, recency, overconfidence and illusion of control, confirmation bias, framing, mental accounting, herding, hindsight, status quo, availability, and the disposition effect (selling winners, holding losers).
Advisor as a source of error
Biases cut both ways: advisors exhibit overconfidence in forecasts, recency in capital-market assumptions, and confirmation in plan reviews. Good practice uses pre-commitment (written IPS), rules-based rebalancing, dollar-cost averaging for lump sums where behavior risk dominates, and framing that reframes volatility as the price of return.
Worked example
A client refuses to rebalance into equities after a drawdown. Reframe using mental accounting: the money needed in three years sits in a laddered bond portfolio; the remainder is long-horizon capital. Pre-commit in writing to a rebalancing band. That converts an emotional decision into a rule.
Traps
- Labeling every disagreement as a "bias."
- Confusing risk tolerance with risk capacity.
- Assuming education alone cures bias; structure and defaults do more work than lectures.
- Forgetting that prospect theory is about changes from a reference point, not absolute wealth.
