The endowment effect occurs when a person assigns greater value to an asset simply because they own it or associate it with personal meaning. The inherited shares are being valued partly because of family attachment rather than solely because of their expected return, risk or role in the portfolio. Option A is correct.

The emotional value does not make the client irrational in a general sense. Personal preferences are legitimate considerations, but the RR must help the client understand the financial consequences. A concentrated inherited position may expose the portfolio to excessive issuer risk, sector risk and liquidity problems. The RR could discuss partial sales, gradual diversification, charitable giving, tax consequences or retaining a limited sentimental position while reducing the concentration.

The gambler’s fallacy involves believing that an independent random event is more likely because of previous outcomes. Hindsight bias makes past events appear more predictable after they occur. Representativeness involves judging an investment based on similarity to a familiar pattern or stereotype.

The RR should not ignore the client’s attachment or force a transaction. The appropriate process is to explain the risks, present reasonable alternatives and document the client’s informed decision.

The Retail Securities syllabus expressly includes the endowment effect, loss aversion, overconfidence and other emotional and cognitive biases in investment recommendations.
