According to Jane Street, the NSE report concluded that in 48 out of 53 time slots examined, there was no case of manipulation. Similarly, SEBI’s internal surveillance report said it could not be established that Jane Street had unduly benefited from its trading activity or influenced Bank Nifty, recommending that the matter need not be pursued.
The US high-frequency trading firm told SAT it was “shocked” to discover that these reports predated SEBI’s July order but were not shared with it. SEBI on July 4 temporarily barred Jane Street from the local market on allegations that it manipulated India’s key indexes, in one of the strongest actions it has taken against a foreign investor.

SEBI, however, dismissed the plea as a “fishing expedition” for documents. The capital markets regulator said it had already shared around 10 GB of data with Jane Street and maintained that the investigation was still ongoing. “We cannot disclose further details while the probe is incomplete,” SEBI told the tribunal.
The Tribunal has scheduled a further hearing in the matter on November 18.
