Market Surveillance and Investor Protection in the Secondary Market

Updated 11 October 2026 · Fact-checked

Market surveillance is the monitoring of trading to detect manipulation, insider trading and abnormal price moves. Exchanges use circuit breakers and alerts. SEBI protects investors under Section 11 of the SEBI Act by regulating, inspecting, and passing orders such as suspension, attachment and cease and desist. Answer by stating the provision, applying it, then concluding.

Understand Market Surveillance and Investor Protection

A secondary market works only if investors trust it. Trust breaks when prices are rigged, insiders trade on secrets, or sudden crashes spread panic. Market surveillance is the system that watches for these problems and acts early.

Surveillance happens at two levels. Stock exchanges watch their own trading in real time. They track unusual price and volume moves, concentrated trading by a few clients, and patterns that look like rigging. They can put a stock under closer watch, restrict trading in it, or refer the matter to SEBI. SEBI sits above the exchanges. It supervises them and acts against wrongdoers.

Circuit breakers are a volatility control. They halt or limit trading when prices move beyond set limits in a day. The aim is a cooling-off period so that fear or rumour does not drive prices. The exact percentage bands and time-outs are set by SEBI and the exchanges and can change, so learn the concept and check the latest figures in your study material.

Section 11(1) of the SEBI Act, 1992 makes it SEBI's duty to protect the interests of investors in securities and to promote the development of, and regulate, the securities market. Section 11(2) lists measures. Examples are regulating business in stock exchanges, registering and regulating intermediaries, prohibiting insider trading, regulating substantial acquisition of shares and takeovers, calling for information, inspecting and auditing, and promoting investor education.

Section 12A bars manipulative and deceptive devices, fraud and insider trading in listed or proposed-to-be-listed securities. Section 15G imposes the insider trading penalty. Together these give you the three layers to write about: prevention (surveillance and rules), intervention (orders under Section 11 and 11D), and punishment (penalties).

Key rules to remember

SEBI's core duty
Section 11(1): protect investors + promote development of + regulate the securities market
Use this as the opening line in any answer on SEBI's role in investor protection.
Interim measures by order (Section 11(4))
Reasons recorded in writing + interests of investors or market + pending or after investigation
Measures include suspending trading of a security, restraining persons from the market, suspending office-bearers of an exchange, impounding proceeds, attaching bank accounts or property, and directing not to dispose of assets. A hearing must be given before or after the order.
Attachment limit (Section 11(4)(e))
Attachment up to 90 days; confirmation from the Special Court within 90 days
Only property, bank accounts or transactions relating to proceeds actually involved in the violation may be attached.
Cease and desist (Section 11D)
Inquiry + person has violated or is likely to violate the Act, rules or regulations = order to cease and desist
For a listed public company, or a public company intending to list (other than intermediaries under Section 12), SEBI needs reasonable grounds to believe it has indulged in insider trading or market manipulation.
Prohibited conduct (Section 12A)
No person shall directly or indirectly use manipulative or deceptive devices, defraud, engage in insider trading, or deal while in possession of material or non-public information
Applies to securities listed or proposed to be listed on a recognised stock exchange.
Insider trading penalty (Section 15G)
Not less than ₹10 lakh; may extend to the higher of ₹25 crore or 3 × profits made
Covers dealing on the basis of UPSI, communicating UPSI (except in the ordinary course of business or as required by law), and counselling or procuring another to deal.
Disgorgement (Section 11(5))
Amount disgorged → credited to the Investor Protection and Education Fund
Used by SEBI in accordance with the regulations made under the Act.

How to solve Market Surveillance and Investor Protection questions

Use this method for any question on surveillance, circuit breakers or SEBI's investor protection powers.

  1. 1Identify what is asked: a surveillance tool, a SEBI power, a prohibition, or a penalty.
  2. 2Name the source: Section 11 (functions and orders), 11D (cease and desist), 12A (prohibitions) or 15G (insider penalty).
  3. 3State the rule in plain words with its conditions, for example reasons recorded in writing, hearing, 90-day attachment.
  4. 4Apply it to the facts: who acted, what they did, and which clause fits.
  5. 5Choose the right remedy: interim order, cease and desist, penalty, or disgorgement.
  6. 6Check for conditions or exceptions, such as the proviso for listed public companies.
  7. 7Close with a clear conclusion that answers the exact question asked.

Quickest way: Three-layer answer: prevent, intervene, punish

When to use it: For short-note or descriptive questions such as 'How does SEBI protect investors in the secondary market?' when time is limited.

  1. Start with Section 11(1) in one line.
  2. Prevent: exchange surveillance, circuit breakers, regulation and inspection of exchanges and intermediaries, investor education.
  3. Intervene: Section 11(4) orders and Section 11D cease and desist.
  4. Punish: Section 12A prohibitions, Section 15G penalty, and disgorgement to the Investor Protection and Education Fund.
  5. Add one line of conclusion.

Common mistakes in Market Surveillance and Investor Protection

  • Saying SEBI can attach property indefinitely.

    Students remember 'attachment' but not the time limit.

    Fix: Write that attachment under Section 11(4)(e) is for up to 90 days, within which the Special Court must confirm it.

  • Stating fixed circuit breaker percentages as permanent law.

    Bands are memorised from notes that may be outdated.

    Fix: Explain the purpose and mechanism. Quote percentages only from the latest study material and say they are set by SEBI and the exchanges.

  • Mixing up Section 12A and Section 15G.

    Both relate to insider trading.

    Fix: Section 12A prohibits the conduct. Section 15G prescribes the penalty for insiders.

  • Quoting the insider trading penalty wrongly, for example as only ₹25 crore.

    Students recall one limit and forget the alternative.

    Fix: Write: minimum ₹10 lakh, maximum the higher of ₹25 crore or three times the profits made.

  • Ignoring the hearing requirement for Section 11(4) orders.

    The power looks absolute when read quickly.

    Fix: Add that reasons must be recorded in writing and SEBI must give the persons concerned an opportunity of hearing, before or after the order.

  • Treating cease and desist as a penalty.

    Both are enforcement orders.

    Fix: Cease and desist directs a person to stop a violation, actual or likely. Penalty is a separate monetary consequence.

Worked examples

Example 1

Explain the measures SEBI may take under Section 11(4) of the SEBI Act, 1992 to protect investors while an investigation is pending.

Show the solution
  1. Provision: Section 11(4) lets SEBI pass an order, for reasons recorded in writing, in the interests of investors or the securities market, either pending or on completion of an investigation or inquiry.
  2. Measures: suspend trading of any security on a recognised stock exchange; restrain persons from accessing the securities market and prohibit persons associated with it from dealing; suspend an office-bearer of an exchange or self-regulatory organisation; impound and retain proceeds or securities of a transaction under investigation.
  3. Further measures: attach bank accounts or property for up to 90 days; direct an intermediary or associated person not to dispose of or alienate an asset under investigation.
  4. Safeguards: the Special Court must confirm attachment within 90 days, only proceeds actually involved in the violation may be attached, and SEBI must give a hearing before or after the order.
  5. Conclusion: these are interim, reasoned and hearing-based powers meant to freeze the harm while the inquiry continues.

Answer: Under Section 11(4), SEBI may suspend trading, restrain market access, suspend exchange office-bearers, impound proceeds, attach property for up to 90 days (subject to Special Court confirmation) and bar disposal of assets. It must record reasons and give a hearing.

Example 2

Rohan, a director of a listed company, learns of an unannounced merger and tells his friend Meera. Meera buys shares before the announcement and earns a profit of ₹2 crore. Discuss the consequences under the SEBI Act, 1992.

Show the solution
  1. Provision: Section 12A(d) and (e) bar insider trading and dealing while in possession of material or non-public information. Section 15G penalises an insider who deals on UPSI, communicates UPSI (except in the ordinary course of business or under law), or counsels or procures another to deal.
  2. Facts: Rohan, a director, is an insider. He communicated UPSI to Meera, not in the ordinary course of business. Meera dealt while in possession of that information.
  3. Penalty for Rohan: Section 15G(ii) applies. The penalty is at least ₹10 lakh and up to the higher of ₹25 crore or three times the profit made.
  4. Compute the profit limit: 3 × ₹2 crore = ₹6 crore. This is lower than ₹25 crore, so the upper limit is ₹25 crore.
  5. Other action: SEBI may pass interim orders under Section 11(4), such as impounding the proceeds, and may order disgorgement, which is credited to the Investor Protection and Education Fund.
  6. Conclusion: Rohan is liable to a penalty between ₹10 lakh and ₹25 crore. Meera's dealing breaches Section 12A and exposes her to SEBI action and disgorgement.

Answer: Rohan is liable under Section 15G for communicating UPSI: a penalty of at least ₹10 lakh and up to ₹25 crore, as three times the profit (₹6 crore) is lower. Meera's trading breaches Section 12A, and SEBI may impound or order disgorgement of the profit.

Exam tips

  • Open with Section 11(1) in investor protection answers. It earns easy marks and frames the rest.
  • Learn the Section 11(4) list as a group of six measures and always add the safeguards: written reasons, 90-day attachment, hearing.
  • For circuit breakers, explain why they exist and how they work. Quote percentages only if you are sure they are current.
  • In case-style questions, name the section, apply it to the facts, then conclude with the penalty range or order.
  • Keep the ₹10 lakh, ₹25 crore and three-times-profit figures ready for Section 15G.

Market Surveillance and Investor Protection: frequently asked questions

What is market surveillance in a stock exchange?

It is the continuous monitoring of trading to spot manipulation, unusual price or volume moves and insider trading. Exchanges act on alerts and refer serious cases to SEBI. SEBI supervises both exchanges and market participants.

What are circuit breakers in the stock market?

They are limits that pause or restrict trading when prices move too far in a day. The pause gives investors time to react calmly to news. The exact bands are fixed by SEBI and the exchanges and may change.

How does SEBI protect investors in the secondary market?

SEBI regulates exchanges and intermediaries, inspects and inquires, prohibits insider trading and manipulation, and promotes investor education. It can pass interim orders, cease and desist orders and levy penalties. Money disgorged goes to the Investor Protection and Education Fund.

Can SEBI pass a cease and desist order against a listed company?

Yes, but only where it has reasonable grounds to believe the company has indulged in insider trading or market manipulation. This condition is in the proviso to Section 11D. For others, an inquiry finding a violation or likely violation is enough.
