Shares of all 10 Adani group companies ended in the green on Monday, adding Rs 82,000 crore in market value on the first day of trading following the clean chit given by a Supreme Court-appointed expert committee probing regulatory failures with regards to related-party transactions and alleged manipulation of the conglomerate’s stocks.

Monday’s gains marked the biggest increase for Adani stocks since the freefall triggered by the 24 January release of activist short-seller Hindenburg Research’s report accusing the conglomerate of various irregularities, including stock price manipulation. The gains also took the group’s total market capitalization to Rs 10,17,685 crore, the highest since the release of New York-based Hindenburg’s report, according to BQ Prime.

Adani Enterprises, the group’s flagship firm, was the top performer among the Nifty 50 stocks, climbing 19.55% to end at Rs 2,338.55. Adani Wilmar closed 10% higher at Rs 444.30. Adani Ports and Special Economic Zone rose 6.41%; Ambuja Cements 5.72%; Adani Green Energy, Adani Power, Adani Total Gas, Adani Transmission and NDTV gained 5% each, while ACC ended 4.91% higher.

The Nifty, the National Stock Exchange’s 50-stock benchmark index, rose 0.61% to end at 18,314.40 points, outperforming the BSE’s 30-share Sensex, which gained 0.38% to close at 61,963.68. Adani group stocks have a 2% weight on the Nifty 50, but are not a part of the Sensex.

The sentiment toward the Adani group has changed markedly from a week ago, when worries over the exclusion of some stocks from MSCI indexes and potential equity dilution from fundraising plans by two companies renewed a selloff, according to Bloomberg. Adani stocks lost around Rs 82,000 crore in market value last week.

No ‘systemic’ impact: In its report—submitted earlier this month but made public last week—the SC-appointed committee said even though volatility in Adani stocks was high, the Indian market as a whole was not “unduly volatile” amid events related to the group after the short-seller report was published.

The six-member panel, citing data from SEBI, said the impact of Adani-related events on the overall market was low. It further said that the events around the Adani group did not have any “significant impact” on Indian markets at a “systemic level.” Read more: SC panel report on Adani: A roundabout way of saying nothing.
