SEBI penalises trader in BSE illiquid stock options case
SEBI has imposed a Rs 5 lakh penalty on Sonia Chadha for non-genuine reversal trades in illiquid stock options on the BSE, part of a matter naming 14,720 entities.
The Enforcement Action
The Securities and Exchange Board of India (SEBI) has imposed a penalty of Rs 5,00,000 on Sonia Chadha for executing what its adjudicating officer found to be non-genuine reversal trades in illiquid stock options on the BSE. The penalty was ordered by Adjudication Order No. Order/MS/BK/2026-27/32494 dated 17 July 2026, signed at Mumbai by adjudicating officer Medha Sonparote. The order was passed under Section 15-I of the SEBI Act, 1992 read with Rule 5 of the SEBI (Procedure for Holding Inquiry and Imposing Penalties) Rules, 1995.
Per the order, SEBI found that Chadha violated Regulations 3(a), (b), (c), (d), 4(1) and 4(2)(a) of the SEBI (Prohibition of Fraudulent and Unfair Trade Practices Relating to Securities Market) Regulations, 2003, commonly called the PFUTP Regulations. The penalty was imposed under Section 15HA of the SEBI Act, which the order reproduces as prescribing a penalty for fraudulent and unfair trade practices relating to securities.
The action is a single strand of a much larger matter. SEBI's order records that its investigation into the BSE stock options segment, completed in 2018, found that 14,720 entities were involved in executing non-genuine trades, with action initiated against them, in the order's words, "in a phased manner". Chadha's order is one of a continuing stream of adjudication and recovery documents SEBI has issued in the same matter.
Chadha's on-record response, per the order, was limited. She contended that after the lapse of more than ten years she no longer possessed the relevant records and, citing Indian tax law, that she was "only required to keep records for a period of 7 years". SEBI records that she did not file a substantive reply dealing with the allegations on their merits.
How the Scheme Worked
The matter dates back to SEBI's observation of what it called large scale reversal of trades in the stock options segment of the BSE. According to the order, SEBI investigated trading in illiquid stock options for the period 1 April 2014 to 30 September 2015, which it calls the investigation period. Across that window, the order states, a total of 2,91,744 trades, some 81.40% of all trades executed in the BSE stock options segment, were allegedly non-genuine and created artificial volume.
The order describes a reversal trade as one in which an entity reverses its buy or sell position in a contract with a subsequent sell or buy with the same counterparty during the same day. Because the option contracts were illiquid, with little or no genuine trading, SEBI's position is that there was no real price discovery, so the trades served no commercial purpose other than to manufacture the appearance of activity.
In Chadha's case, the order states she executed 8 non-genuine trades in 4 contracts, generating an artificial volume of 88,000 units. The order sets out one illustration in detail. On 18 May 2015, in the contract "GRSM15JUN3150.00PE", she sold 7,000 units at Rs 56 to a counterparty named Welcome Enterprises at 12:40:47, and then, at 12:40:53 the same day, six seconds later, bought 7,000 units back from the same counterparty at Rs 18. SEBI treats the wide price gap over a few seconds, with the same counterparty and identical quantity, as evidence of what it describes as "a prior meeting of minds" to trade at a pre-determined price. The order records similar trades with Welcome Enterprises and with another counterparty, Blue Bull Equities Private Limited.
Procedurally, the order traces a long history. SEBI passed an interim order on 20 August 2015, confirmed by orders in July and August 2016, and disposed of those proceedings by a final order dated 5 April 2018. A show-cause notice was issued to Chadha on 11 August 2022; a post show-cause intimation followed on 6 March 2024. The order notes she was offered the SEBI ISO Settlement Schemes of 2022 and 2024 but availed neither. After several changes of adjudicating officer and repeated hearing adjournments, hearings were held in July 2026 before the order was passed.
The Law Invoked
The order rests on the PFUTP Regulations, 2003. Regulation 3 prohibits dealing in securities in a fraudulent manner or using any manipulative or deceptive device or contrivance. Regulation 4(1) bars any person from indulging in a fraudulent or unfair trade practice, and Regulation 4(2)(a) deems as such any act "which creates false or misleading appearance of trading in the securities market". SEBI found all six cited limbs, namely 3(a), (b), (c), (d), 4(1) and 4(2)(a), to be established.
The penalty itself flows from Section 15HA of the SEBI Act, 1992, which prescribes a penalty of not less than five lakh rupees, extending up to twenty-five crore rupees or three times the profits made, whichever is higher, for fraudulent and unfair trade practices. In fixing the amount, the order applies Section 15J of the SEBI Act, which requires regard to the disproportionate gain made, the loss caused to investors, and the repetitive nature of the default. SEBI noted that the record did not quantify any gain or investor loss, and set the penalty at the statutory floor of Rs 5 lakh.
The order also relies on Supreme Court precedent, including SEBI v Kishore R Ajmera and SEBI v Rakhi Trading Private Limited, for the principle that synchronised reversal trades can be inferred to be manipulative on the preponderance of probabilities, even without direct proof of a meeting of minds.
What Happens Next
Under the order, Chadha must pay the Rs 5 lakh penalty within 45 days of receiving it, through SEBI's online payment facility. The order warns that failure to pay may trigger recovery proceedings under Section 28A of the SEBI Act, including attachment and sale of movable and immovable property.
That recovery machinery is visible elsewhere in the same matter. In the same week, SEBI issued recovery documents against other named entities in the illiquid stock options matter, including a demand notice under Recovery Certificate No. 9225 of 2026 and completion and release orders in other recovery certificates. These are the enforcement steps that follow when a penalty is not paid within the prescribed window.
An adjudication order of this kind is a regulatory finding, not a criminal conviction, and it is appealable. A person aggrieved by a SEBI adjudication order may appeal to the Securities Appellate Tribunal (SAT) within the prescribed period, and thereafter to the Supreme Court on a question of law. Until any such appeal is decided, the order stands as SEBI's finding in the matter, and due process continues through the appellate route.
What It Means
For ordinary investors, the practical lesson is less about this one Rs 5 lakh penalty and more about the pattern it represents. Reversal trading in illiquid options was, in SEBI's telling, used to manufacture volume, and in many documented instances of this category to book artificial profits or losses. Retail investors who see sudden bursts of volume in obscure, thinly traded contracts should treat that as a reason for caution, not comfort.
There is also a verification takeaway. Anyone can check whether an intermediary offering to trade on their behalf is registered by using SEBI's public intermediary and registration look-ups on sebi.gov.in, and can read enforcement orders directly on the website. The matter shows how long enforcement can take, here roughly a decade from the investigation period to this order, a reminder that a clean-looking counterparty today may still be the subject of proceedings years later. It also underlines that record-keeping cuts both ways: Chadha's stated inability to retrieve decade-old records did not, per the order, excuse a reply on the merits, so investors who trade should retain contract notes and statements well beyond the minimum tax-record period.
FAQ
What exactly did SEBI order?
SEBI imposed a penalty of Rs 5,00,000 on Sonia Chadha under Section 15HA of the SEBI Act, 1992, having found violations of Regulations 3 and 4 of the PFUTP Regulations, 2003. The order is dated 17 July 2026 and bears reference number Order/MS/BK/2026-27/32494. The penalty is payable within 45 days of receipt.
Is a SEBI penalty the same as a criminal conviction?
No. A SEBI adjudication order is a civil, regulatory finding by the regulator, not a criminal conviction by a court. It is appealable to the Securities Appellate Tribunal and, on a question of law, to the Supreme Court. Until an appeal is decided, the order stands as SEBI's finding, and due process continues through the appellate route.
What is a reversal trade in illiquid options?
Per the order, a reversal trade is one where an entity reverses its buy or sell position in a contract with a subsequent, opposite trade with the same counterparty on the same day. In an illiquid contract with little genuine trading, SEBI treats such synchronised trades as creating a false appearance of volume.
Can the order be appealed?
Yes. A person aggrieved by a SEBI adjudication order may appeal to the Securities Appellate Tribunal within the period prescribed under the SEBI Act, and may pursue a further appeal to the Supreme Court on a question of law. The order does not become final while a timely appeal is pending.
How can I check if my broker or adviser is registered?
Use the registration and intermediary look-up tools on the SEBI website, sebi.gov.in, which let you verify whether an entity holds a valid SEBI registration. You can also read SEBI's enforcement orders directly on the site to check whether an intermediary faces proceedings.
