How do individuals make decisions?

System 1 is fast, automatic, and emotion‑driven. It relies on mental shortcuts and operates with little conscious effort. For an Indian retail investor, System 1 may trigger an immediate reaction to a market news headline, such as buying a stock after seeing a celebrity endorsement.

System 2 is slower, analytical, and deliberative. It requires effortful thinking, such as calculating the expected return of a mutual fund or comparing expense ratios. In exam scenarios, you will be asked to recognise when an adviser should encourage a shift from System 1 to System 2 to avoid impulsive errors.

Why it matters for the exam: SEBI expects advisers to assess the client’s decision‑making style and mitigate undue reliance on System 1. Questions often present a client’s reaction and ask which bias is at play and what advisory step is appropriate.

• System 1 – quick, intuitive, prone to bias.
• System 2 – slow, logical, reduces bias.

Heuristics are mental shortcuts that simplify complex decisions. The most frequently tested heuristics in the NISM syllabus are availability, representativeness and anchoring. Availability bias leads investors to over‑weigh recent or vivid information – for example, buying a fund that performed well last month while ignoring its long‑term track record.

Representativeness bias causes investors to judge an asset based on superficial similarity to a known pattern, such as assuming a start‑up in the fintech space will succeed because it resembles a previously successful unicorn. This can lead to mispricing and poor portfolio construction.

Anchoring occurs when an initial piece of information – say, a stock’s 52‑week high – becomes a reference point that distorts subsequent valuation judgments. Advisers must recognise these biases to ask probing questions and provide calibrated advice.

• Availability – recent events dominate perception.
• Representativeness – pattern matching overrides fundamentals.
• Anchoring – undue reliance on an initial figure.

Prospect theory, introduced by Kahneman and Tversky, replaces the traditional utility model by emphasizing that investors evaluate outcomes relative to a reference point, typically the status‑quo. The value function is concave for gains and convex for losses, reflecting loss aversion – losses feel roughly twice as painful as equivalent gains.

Framing effects arise when the same financial information is presented in different ways. For instance, an adviser saying "this fund has a 70% chance of earning a positive return" versus "there is a 30% chance of a negative return" can lead to opposite client reactions, even though the probabilities are identical.

Exam relevance: NISM questions may present two statements with identical statistical content but different wording and ask which is more likely to induce a purchase decision. Recognising framing helps you choose the correct advisory response.

Mental accounting describes how investors compartmentalise money into separate "accounts" – for example, treating a windfall as a gambling fund while viewing salary savings as a retirement nest‑egg. This leads to inconsistent risk‑taking across accounts, violating the principle of portfolio optimisation.

Framing interacts with mental accounting when advisers present the same investment option in different mental buckets. Describing a mutual fund as "your holiday savings" may encourage higher risk tolerance than labeling it "your retirement savings".

For the exam, you may be asked to identify the bias and suggest a corrective advisory technique, such as consolidating accounts and presenting a unified risk‑return profile.

Advisers must actively screen for behavioural biases during the KYC and suitability assessment. SEBI’s Investment Adviser Regulations mandate that advisers disclose material risks and ensure that recommendations are in the client’s best interest, which includes mitigating irrational decision‑making.

Practical steps include: using structured questionnaires to uncover bias, presenting information in neutral frames, employing visual aids (e.g., risk‑return scatter plots), and encouraging a "cool‑down" period for high‑emotion decisions. Advisers should also document the discussion of biases as part of the compliance record.

Exam tip: Questions often pair a client scenario with a recommended advisory action. Choose the option that explicitly mentions bias mitigation (e.g., "request a 48‑hour reflection period" or "re‑present performance using a 5‑year horizon").
