SEBI has barred US-based Jane Street Group from participating in the Indian stock market and ordered it to disgorge unlawful gains of ₹4,843 crore for allegedly manipulating stock indices through derivative positions.

SEBI’s Rs 4,840 crore crackdown on Jane Street rattles Indian capital markets; Nuvama stock falls sharply amid investor concerns over past trading links.

Traders worry exit of a major expiry-day player could shrink market depth and raise volatility; sentiment may take a hit even as SEBI’s crackdown is welcomed for long-term fairness.
