SEBI Shares Trade Logs as Jane Street Challenges Allegations
India’s market regulator, SEBI, accused Jane Street of manipulating prices linked to the Nifty Bank Index.
The regulator says the firm bought many shares while selling options, then sold the shares a few hours later.
It says this helped the firm’s options position and led to unlawful gains.
Jane Street says its trades were ordinary index arbitrage, not manipulation.
SEBI told a court it had given the firm trade logs with times, amounts and prices.
It did not provide the identities and tax details of other traders, saying those records were not used in its investigation.
Jane Street wants additional material, including emails between SEBI and the National Stock Exchange.
The court dispute concerns what information the firm should receive to answer the allegations.
SEBI temporarily barred the firm from trading in India, then lifted the restriction after an escrow deposit.
SEBI told a court it had shared the trade logs used in its preliminary order and urged Jane Street to respond.
SEBI said the logs include trade times, quantities and prices, but omit counterparties’ names and tax identification details.
Jane Street has sought more documents, including communications between SEBI and the National Stock Exchange.
SEBI alleges Jane Street used stock purchases and options sales to influence the Nifty Bank Index and profit from derivatives.
Jane Street denies manipulation; its trading restriction was lifted after it deposited about Rs 4,843 crore in escrow.
- Who
