How do stock exchange surveillance mechanisms—Graded Surveillance Measures (GSM) and Additional Surveillance Measures (ASM)—differ in their triggering criteria and market objectives?

[ A ]GSM is used exclusively for sovereign gold bonds, while ASM is used exclusively for agricultural fertilizer subsidies.

[ B ]Both GSM and ASM are punitive fines imposed on companies that fail to pay annual exchange listing fees.

[ C ]GSM and ASM represent automatic stock trading algorithms that guarantee 100% daily profits to retail traders.

[ D ]GSM targets micro-cap/small-net-worth securities whose market valuations are fundamentally disconnected from underlying financials (e.g., negative PE, abnormal P/B); ASM targets abnormal price/volume volatility, high client concentration, and high intraday swings to protect market integrity.[ CORRECT ]

Takeaway

Option D is correct: GSM targets micro-cap/small-net-worth securities whose market valuations are fundamentally disconnected from underlying financials (e.g., negative PE, abnormal P/B); ASM targets abnormal price/volume volatility, high client concentration, and high intraday swings to protect market integrity.

Derivation

Stock exchanges operate dual surveillance mechanisms to deter price manipulation: (1) Graded Surveillance Measure (GSM): Focuses on micro-caps with low net worth (<= Rs. 10 cr) or small market cap (<= Rs. 25 cr) having abnormal valuations unsupported by fundamentals (e.g., negative PE or PE > 2x benchmark). Securities face trade-for-trade delivery and surveillance margins. (2) Additional Surveillance Measure (ASM): Focuses on abnormal price volatility over 3-12 months, volume spikes, and high client concentration, hiking margins up to 100%. This tests exchange surveillance tools. The common error is assuming GSM/ASM are delisting penalties.

Why the others fail

A — GSM is used exclusively for sovereign gold bonds, while ASM is used exclusively for agricultural fertilizer subsidies.

GSM and ASM are equity secondary market price/volume surveillance frameworks, not sovereign bond or agricultural subsidy mechanisms.

B — Both GSM and ASM are punitive fines imposed on companies that fail to pay annual exchange listing fees.

Surveillance measures are risk-mitigation trading restrictions (margins, price bands), not administrative listing fee penalties.

C — GSM and ASM represent automatic stock trading algorithms that guarantee 100% daily profits to retail traders.

GSM and ASM are regulatory surveillance filters that restrict speculative volatility, having no connection to automated profit algorithms.
