New Delhi:Amid a political furore over a meltdown in the Adani group shares, stock market data shows it is not only the plunge now but the sharp surge of the past also drew regulatory attention and enhanced surveillance. Adani group stocks have taken a huge beating on the bourses, losing billions of dollars in market value, after US-based activist short-seller Hindenburg Research made a litany of allegations, including fraudulent transactions and share price manipulation at the Gautam Adani-led group.
The Adani group has dismissed the charges as lies, saying it complies with all laws and disclosure requirements. The opposition, however, has been calling it a big fraud. The capital markets watchdog, the Securities and Exchange Board of India (Sebi), has also been facing criticism from some opposition leaders that it has not intervened in the matter.
Sebi has said it is committed to ensuring the stock market's integrity and all necessary surveillance measures are in place to address any excessive volatility in individual shares. As per the data available with the stock exchanges, seven Adani group stocks have triggered regulatory surveillance actions during various periods since 2019, on account of both unusual price rise and fall and high promoter pledge. Six listed Adani scrips are under ASM (Additional Surveillance Mechanism) as of February 3, 2023.
Sebi and stock exchanges have put in place additional surveillance measures to address the issue of excessive volatility in specific scrips. Whenever there are sharp movements in the individual stock prices, upper or lower side, the ASM gets triggered automatically. Niranjan Shastri, Associate Professor at SBM (School of Business Management), NMIMS Indore, said the ASM framework first came into force in 2018 when Sebi and exchanges decided that there was a need to bring surveillance in addition to existing measures in force and the ASM shortlisting can happen even if markets are moving upward because price variation, both downward and upward, is one of the parameters.
Other parameters include client concentration, market capitalisation, volume variation and delivery percentage. In a statement on Saturday, Sebi said its mandate is to maintain the orderly and efficient functioning of the market and it has put in place a set of well-defined, publicly available surveillance measures (including the ASM framework) to address excessive volatility in specific stocks.
"This mechanism gets automatically triggered under certain conditions of price volatility in any stock," it said. Stock exchanges BSE and NSE recently put three Adani group companies -- Adani Enterprises, Adani Ports and Special Economic Zone and Ambuja Cements -- under their short-term additional surveillance measure (ASM), which is aimed at curbing speculation and short-selling in these stocks.
"Contrary to the perception that recent fall in Adani stock prices triggered ASM, the rise in prices in these scrips had also triggered ASM a few years back," said a market expert. The measures under ASM include imposing higher upfront margins (even up to 100 per cent), reduction in price band, settlement on gross basis as against normal net basis, etc.
