Dear Reader,

The Panorama newsletter is sent to Moneycontrol Pro subscribers on market days. It offers easy access to stories published on Moneycontrol Pro and gives a little extra by setting out a context or an event or trend that investors should keep track of. In a turn of events that has stirred the trading community, the market regulator SEBI recently unveiled the practices of Jane Street, confirming long-held suspicions about market manipulation by major players. With vast resources at its disposal, Jane Street had been executing a sophisticated intraday index manipulation strategy, leveraging both cash and options segments to bend the market to its will.

What caught the public’s attention, however, was the way it allegedly orchestrated these manoeuvres through various entities. Indian traders found themselves in a precarious position, incurring losses while traders from Jane Street enjoyed substantial profits.

Jane Street also avoided tax obligations in India. It incurred losses in its Indian entities while the foreign ones reaped profits. For every rupee lost locally, these entities garnered profits more than 10 times abroad. The fallout was two-fold, as not only did individual Indian traders suffer, but the government also faced significant tax revenue losses.

This episode served as a crucial lesson in revealing systemic loopholes within the market's framework. It also spotlighted the vulnerabilities in the index construction, where a select few stocks were manipulated to sway the entire index. Many now argue that SEBI and the exchanges must revisit and strengthen these structures to prevent the recurrence of such incidents. The recent decision to omit smaller indices—which were easier to manipulate—from weekly expiries marks a step in the right direction.
