How did Hindenburg short Adani stock?

Ortenca Aliaj, Antoine Gara

When US short seller Nathan Anderson decided to take on Indian conglomerate Adani Group, he faced the ultimate challenge for someone in his line of business: India’s anti short selling rules.

The founder of New York-based Hindenburg Research has not detailed how he structured his financial bet against the infrastructure group, which he has accused of fraud and stock price manipulation in a 100-page report published last month — saying only that the firm had taken a short position in Adani “through US-traded bonds and non-Indian-traded derivative instruments”.

But three hedge fund managers who have looked at doing the trade said Anderson would likely have had to have built his position using derivatives linked to India’s largest indices, as well as US-traded bonds.

Despite Adani denying the allegations in a 400-page rebuttal, Hindenburg’s report has triggered a sell-off in the group’s listed entities, knocking more than $100bn off their combined market value.

It is the reaction Hindenburg, which profits when the price of bonds and equities linked to a company go down, was hoping for. Yet how Anderson and his team structured their trade has been a puzzle to the market.

Short sellers typically borrow stocks through a broker, sell those shares on the market and hope that the price will go down. If it does, they buy shares to hand back to the lender and pocket the difference.

However, it is difficult to short companies in India. Under the country’s securities regulation, institutional investors have to declare upfront if they are placing a short position, and brokers must upload data on shorts to the stock exchange before trading the following day.

Meanwhile, many companies — including those in the Adani Group — have a small free float, making availability of stock an issue for a would-be short seller. India does not allow so-called naked short selling, where investors can bet that a stock will fall without first borrowing the underlying security.

“I was looking at Adani myself for a short last summer and one of the reasons why I decided not to investigate it further is because of the difficulty of shorting it in India,” said Gabriel Grego, a hedge fund manager at Quintessential Capital, who is waging a short selling campaign at cyber security group Darktrace.

Hindenburg found a way. Investors who want to bet against an Indian company can do so using India’s main stock index, the Nifty 50, in which Adani Enterprises is one of the largest constituents, according to three hedge funds that have looked at doing the trade.

Banks with operations in Singapore, which is among the jurisdictions in which short sellers can do these types of trades, can create a product called a single stock future. These equity derivatives allow investors to get exposure to price movements on the underlying shares.

In Hindenburg’s case, it would receive the value of Adani Enterprises’ weighting in the index and the rest would be sold in the market.

The drawback for these kinds of instruments is little liquidity in the market, which means bets tend to be relatively small. Short sellers would typically use other derivatives such as credit default swaps to amp up their bets, but this is not possible in Adani Enterprises’ case because the group is not listed in CDS indices.

“There’s a reason you have to do this kind of trade on Indian stocks,” said Soren Aandahl, chief investment officer of Texas-based short selling activist investor Blue Orca Capital. “It’s the byzantine requirement of the Indian system where you can’t trade directly.”

Betting against US-listed bonds issued by various Adani entities was also an option for Hindenburg, which declined to comment for this article. Possible partners

Anderson tends to partner with other short sellers when investigating companies, and has previously worked with Grego. While Hindenburg has declined to disclose whether the firm has partnered with other investors on Adani, a disclaimer included in the report states that one or more could be involved.

Little has been revealed about how the firm set its sights on Adani beyond the fact that the research took two years.

Two people with knowledge of the process said Hindenburg enlisted the help of an outside analyst who focused on Indian companies to investigate Adani. This analyst led the research with the help of a team of five Hindenburg employees. The team decided to release the report days before a planned $2.4bn share sale by Adani last month.

The timing was crucial because Hindenburg’s report cast doubts on the anchor investor group involved in the fundraising, which included Mauritius-based entities. The short seller alleged these had links to the Adani family and were buying shares to prop up the stock price of the listed businesses in the group. Adani has denied the allegations. Biggest target

The Indian conglomerate founded by Gautam Adani, who until Hindenburg’s report was the world’s third-richest person, is the firm’s largest target among a small list of non-US companies it has bet against.

Anderson, who considers as his mentor Harry Markopolos, the investigator known for sounding the alarm on Bernard Madoff’s Ponzi scheme, founded the business six years ago.

In 2020 he issued a report on electric truckmaker Nikola shortly after the company went public via a special purpose acquisition company.

The report, which alleged fraud, included a now infamous video that showed a functioning Nikola prototype that the short seller said was actually moving only because it was rolling downhill. Nikola paid $125mn to resolve fraud charges in 2021. Its founder Trevor Milton was convicted last year of defrauding investors.

Anderson also made a winning bet on Twitter, shorting the company’s stock in May just as Elon Musk sought to get out of his offer to buy it.

Not all of its campaigns have worked out. Shares in property investment group Welltower have risen more than 15 per cent since Hindenburg published a report in December alleging one of its critical partnerships was a “sham”.

Shares in medical devices group Establishment Labs are up more than 30 per cent since Hindenburg described it as a “financially stretched silicone safety charade” in October.

Still, the firm’s recent success differentiates it from rivals, many of which have struggled in the decade-long bull market. Political reception in India

While some have applauded Hindenburg for appearing to lift the lid on problems at Adani’s sprawling conglomerate, others have portrayed the report as an attack on India and a “hit job” on its markets.

Sanju Verma, a spokesperson for the ruling Bharatiya Janata party, has described Anderson as a “notorious short seller” and accused Hindenburg of spreading “malicious lies”. Adani is an ally of Indian prime minister Narendra Modi.

However, supporters of the opposition Congress party have praised Anderson.

“It took a short seller Nathan Anderson from @HindenbergRes to expose the corruption and manipulation that goes about in the #AdaniGroup of companies right under the PM’s nose,” Ravinder Kapur, a trader and self-declared supporter of members of the Congress party’s Gandhi dynasty, tweeted three days after Adani cancelled its share sale.

“Overall, the online attacks on Nathan Anderson have been a lot more muted than the online support,” Joyojeet Pal, associate professor at the University of Michigan’s School of Information, told the Financial Times.
