Why Adani Group stocks fell? As per market experts the drastic fall in Adani Group stocks has been triggered due to a declining trend in the stock market as well as increased pressure from regulatory authorities especially due to last years damning allegations leveled by US-based short-seller Hindenburg Research that linked former SEBI Chairperson Madhabi Puri Buch and her husband Dhaval Buch to offshore companies allegedly connected to the Adani Group. Additionally US SEC has indicted Gautam Adani Sagar Adani for bribery and defrauding American investors while reports suggest that Swiss authorities have frozen over $310 million in various bank accounts as part of a money laundering investigation against the Adani Group. Notably the Adani Group has vehemently denied all these accusing dubbing them as attempts to tarnish its reputation. Experts have also pointed out that the current global economic landscape which is marred by challenges such as surging interest rates and uncertain policies have also hurt the groups performance especially in sectors like renewable energy and gas that require substantial investments. Over the last three quarters foreign investors have been pulling out of Adani stocks as their stakes have fallen drastically. Apart from these factors US Donald Trumps threat of reciprocal tariffs has added to negative market sentiment further hurting the Adani Groups interests.
