The separation line between arbitration and market manipulation has always been one of the most gray areas in the financial markets-Jane Street has brought the giant in India in India these mysterious borders in acute focus.

Jin Street concluded the results of the Indian organizer, claiming that her actions were “the refereeing of the basic index.”

Purchasing, in essence, is similar to discovering incompatibility and trying to make a profit from it – which is completely legal. It refers to the simultaneous purchase and the sale of the original in different markets to exploit the differences in prices.

On the contrary, the manipulation of the market is an illegal act designed to deceive or distort free and fair operation of the markets – usually by affecting prices or misleading appearance of supply and demand on an unfair advantage.

But when is the arbitration governing illegitimacy?

According to experts to CNBC, discrimination depends on the intention and influence on the market.

If you are the person who pays prices outside the alignment – especially in the lighter markets – to profit on the other side, this manipulation.

On July 3, the Indian Securities and Stock Exchange Council (SEBI) Jin Street Group temporarily prevented Jin Street From participating in the country’s stock markets, the United States trading company in the United States is accused of high -frequency to process the market on a large scale. This includes tactics to process the NIFTY 50 index in India in order to take advantage of large positions in the index options.

According to the 105 -page temporary Sebi order, it was claimed that the company bought large quantities of stocks and futures associated with the NIFTY Bank index, which tracks the performance of the banking sector in India, during the early hours of trading. Then he put large bets expecting a decrease in the index later in the session.

Sebi added that Jane Street then sold these previous purchases, prompting the index to less and increasing the profitability of its options. The organizer argued that this was part of a “deliberate strategy to treat indicators” in favor of the larger and most profitable options.

Sibi said that the huge intensity and size of intervention, as well as the rapid relaxation of the positions “without any reasonable economic logic,” was considered manipulation.

Jin Street informed the employees in an internal email message that she had planned to challenge the ban and will later deposit $ 567 million in the guarantee account on July 14, according to Sebi directives, and not before requesting permission to resume trading in the country and lift restrictions.

Key: Raya Men

With the start of the legal and backward decline, the veterans of the industry said that the difference between legal arbitration and illegal manipulation is not always clear.

Bradib Yadaf, a professor of finance at the University of Oklahoma, said that the intention behind the violations of trading – known as Raya’s men, which means the “guilty mind” in Latin – is the key to determining the manipulation. He also pointed out that creating an opportunity to arbitrate by influencing prices in a lower market is what expresses the line to illegitimacy.

“The arbitration turns into the marketing of the market when it creates arbitration by manipulating the less liquid markets in the market,” he said, explaining that the options market in India is very liquid thanks to the large size of buyers and sellers. However, the country’s markets and futures are less than that, which makes it easy to pay prices by putting large deals enough.

This type of arbitration, despite its aggression, is legal and is often useful for market efficiency.

The Sibi case depends on the demands. First, Jane Street has distorted the least -profit money market in the liquid options market. In fact, Sibi, in her temporary matter, was martyred against Jin Street, by a previous ruling on the case, “No one intentionally trades for a loss. The deliberate trading of loss itself is not real dealing in securities.”

Second, its profits came completely from the options, with fixed losses in stocks and futures, indicating that trading was designed to move prices instead of reflecting the real market views.

The professor said in the normal situation in the markets, “The prices may be fine, but if you are a price, then added in the normal situation in the regular markets,” The prices “are” Raya “is a demonstration of the bad intention to manipulate the market … If the prices are not already specified, then their arbitration is fine. Treatment. ” In his opinion, the defect indicates that it was not a state of classic arbitration.

Other experts have also confirmed that the exact line between the manipulation of the market and the conqueror lies in the intention.

However, V Raghunathan, a former member of the Board of Directors of the Sebi Primary Market, believes that the actions of Jane Street were within the legal field. He said that Jin Street is flourishing in the exploitation of exact deficiencies – for example, in ETF pricing against basic securities, or between exchanges.

“This type of arbitration, despite its aggression, is legal and is often useful for the efficiency of the market,” CNBC told CNBC.

He pointed to an example of cumin pleasure – as companies benefit from small time delays in market data across places – as parasitic or predatory criticism, but barely illegal.

However, Ragonathan indicated that the broader anxiety is whether the Jin Street strategies are close to manipulation – either in intent or rhetoric.

Like other experts with whom CNBC spoke, Raghunathan has created manipulation of the market as misleading or deliberately influencing prices and trading volumes to create artificial trends or unfair advantages, such as pumps, discharge and washing circulation.

“Unless Jin Street is found to put deceptive orders, such as deception, misuse of confidential information, or price manipulation to create artificial movements – they have not been accused of them – they will not be considered to have been involved in manipulating the market,” he said.

Paul Rawadi, research manager at Alphaculation Research, said that the lines between manipulation and arbitration also depend on the organizer’s teeth. In the United States, similar allegations depend on whether a company is involved in deception or deception.

“Trading strongly is not a crime,” he said.

Market observers also have echoed that the Jin Street issue highlights the weaknesses of the market structure in India – including liquidity imbalances between website markets and options – which advanced players can legally exploit, but organizers may now seek to tighten them.

According to Sibi, A recent study Of 9.6 million derived traders from individual stocks, they revealed that 91 % lost money last year.

As a former lawyer at SEC, the HowerD Fischer puts it, the pleasure is closer to “looking at the home of a person, and sees that he keeps chimneys of lighting newspapers and candles everywhere, and taking out the insurance on the fire in his home.”

“The manipulation gives him a gift on the fourth of July of fireworks and propane tanks,” said Fisher, who is now a partner in the law office, Moussa, and is present.

Discrimination lies in intention: the exploitation operations in the argument; Tampering is trying to manufacture it.
