UPSC Prelims 2023— Question 73

This question tests Beta in Finance under Financial Markets. The central point is Beta measures a stock’s sensitivity to overall market movements. Option A: the process of simultaneous buying and selling of an asset from different platforms. This distractor is not the keyed answer because it conflicts with the specific factual relationship, chronology, institutional role, geographic association or conceptual distinction tested in the question. Option B: an investment strategy of a portfolio manager to balance risk versus reward. This distractor is not the keyed answer because it conflicts with the specific factual relationship, chronology, institutional role, geographic association or conceptual distinction tested in the question. Option C: a type of systemic risk that arises where perfect hedging is not possible. This distractor is not the keyed answer because it conflicts with the specific factual relationship, chronology, institutional role, geographic association or conceptual distinction tested in the question. Option D: a numeric value that measures the fluctuations of a stock to changes in the overall stock market. This is the keyed answer because it matches the governing fact or concept: Beta measures a stock’s sensitivity to overall market movements. The question should be approached by checking each statement independently rather than accepting a familiar phrase at face value. This is particularly important in UPSC questions where a single incorrect institutional attribution, location, chronology, absolute word or causal link can invalidate an otherwise plausible option. The broader revision takeaway is to connect the keyed answer with the underlying concept rather than memorizing only the letter. The options also illustrate how UPSC constructs distractors by mixing correct facts with one altered detail. In revision, candidates should therefore retain both the positive fact and the nearest contrasting fact so that the same concept can be recognized when the framing changes in another year.
