Of the 18 cases, 15 are known as “intraday index manipulation” and three as “prolonged marking the shut” methods. In keeping with Sebi, the 2 methods allowed Jane Avenue to artificially transfer index ranges to profit from pre-existing choices positions.
Right here’s how these two methods allegedly labored in tandem:
Jane Avenue would maintain disproportionately massive index choices positions even earlier than an expiry day started—sometimes in Financial institution Nifty places (bearish bets) and calls (bullish bets)—relying on market path. In the meantime, within the money and futures market, the agency would execute trades at a loss, serving to push the indices in a path beneficial to its choices positions.
Let’s image that in additional element.
On expiry mornings, Jane Avenue would allegedly purchase massive volumes of Financial institution Nifty constituent shares and corresponding futures contracts. It might make these trades aggressively so they’d artificially drive the Financial institution Nifty index larger. On the similar time, Jane Avenue would enhance its bearish positions in choices—shopping for places and promoting calls—anticipating a reversal later within the day.

The aggressive promoting pushed down costs in Financial institution Nifty shares and the Financial institution Nifty itself.

These trades—focused at Financial institution Nifty and Nifty constituents and futures—pushed the closing index stage to a worth beneficial for its massive choices portfolio.
