F&O trading faces reset as Sebi revisits ‘open interest formula’

The Securities and Exchange Board of India (Sebi) has proposed a raft of new measures aimed at reducing risks and the potential for manipulation in the equity derivatives market while ensuring a stronger alignment with the cash market. Key proposals include a new methodology for calculating open interest (OI) using a ‘delta’ framework, a review of marketwide position limits (MWPL), and the introduction of position limits for single stocks and index derivatives. 

The new proposal comes close on the heels of six measures introduced by Sebi to curb frenzy in index derivatives. 

These measures — a majority of which have already been implemented — have nearly halved trading volumes.

The fresh proposals may not materially affect traders but could help reduce the frequency of stocks entering the ban period, thereby simplifying their trading experience. The changes also aim to enhance market integrity and ensure a more accurate reflection of market conditions. 

The market watchdog has proposed a new metric called ‘future equivalent’ or a delta-based framework for calculating open interest in futures and options (F&O).

Delta refers to the change in an option’s price when the price of the underlying security changes in the cash market. 

At present, open interest (OI) is measured by adding notional OI in futures and options. OI is key to gauging trader activity and sentiment.

“A more meaningful approach would be to aggregate the delta or future equivalent of options positions with futures OI, thereby reflecting the true price sensitivity of outstanding positions,” observes the consultation paper. 

Sebi also plans to link MWPL to the underlying cash market. 

MWPL refers to the maximum number of open F&O contracts allowed for a single stock. 

Once a scrip exceeds MWPL, further trading in its derivatives is restricted. The regulator has proposed a mechanism to offset trades instead of merely squaring off positions when a stock enters the ban period. The move is intended to help traders reduce their risks.

For instance, if a trader holds a long futures position, they could buy put options or sell call options to reduce total delta exposure. 

Currently, MWPL for each stock is 20 per cent of the stock’s free-float market capitalisation (mcap) and is applied to the total notional OI of F&O. 

Sebi has proposed reducing it to 15 per cent of free-float mcap or 60x the average daily delivery value (ADDV) in the cash market, whichever is lower. This metric will be recalculated every three months based on rolling ADDV. 

The new methodology is expected to reduce instances of stocks moving into the ban period by 90 per cent.

The regulator may also explore the need for an MWPL for index derivatives in the future. 

The new methodology will also be incorporated when considering exposure limits for mutual funds (MFs) and alternative investment funds in derivatives to ensure that it accounts for leverage in long options. Further, Sebi is considering imposing individual entity-level position limits for single scrips so that no single entity, such as a foreign portfolio investor (FPI), stockbroker, or MF, can unduly influence the market. 

Sebi has proposed increasing the end-of-day limit for index futures from ₹500 crore to ₹1,500 crore, considering the rise in market size and trading volumes since March 2020. The intraday limit for the same has been proposed at ₹2,500 crore to facilitate market-making.

Similar revisions have been proposed for index options as well. 

Another key proposal is introducing pre-open and post-closing sessions for derivatives, similar to those in the cash market, to enhance price discovery. 

“This is especially useful, as today there are fewer than 40 stock options with complete liquidity and fewer than 25 that can be traded at a scale of a few hundred crores. These reforms put in place a basis for a more efficient, open derivatives market, but they will succeed only if investors and traders learn to adapt to the new regime,” said Rahul Ghose, chief executive officer of Hedged.in.

Further, Sebi has proposed additional conditions to allow derivatives for sectoral and thematic indices. Such an index must have at least 14 constituents, with the weight of the top constituent not exceeding 20 per cent and the combined weight of the top three not exceeding 45 per cent. 

The clarity will help exchanges offer derivatives on more indices.

Markets may remain range bound this year: Kotak Institutional Equities

Kotak Institutional Equities is of the view that the markets are likely to remain range bound this year, as they continue to trade above historical averages and at a significant premium to the MSCI Emerging Markets (EM) index. 

Pratik Gupta, chief executive officer (CEO) and co-head of institutional equity at Kotak Securities, noted that the Nifty is currently trading at a price-to-earnings (PE) multiple of 19 times based on March 2026 earnings estimates. 

This valuation appears elevated, considering earnings are expected to compound at 14 per cent in FY26 and FY27, with potential downside risks to these estimates.

“Given this, we do not foresee a meaningful upside for the Nifty in the short term,” said Gupta, who shared insights from Kotak’s recent investor conference. 

However, the downside for the Nifty is cushioned by India’s robust medium-term growth prospects, which are expected to sustain elevated valuations.

Additionally, a more favourable foreign and domestic liquidity environment in the second half of 2026 could provide further support. 

Kotak Institutional Equities remains cautious about the outlook for small and midcap stocks, as their valuations have not moderated significantly despite recent market corrections. 

The brokerage highlighted key downside risks for the broader market, including a sharper-than-expected global slowdown, a deficient monsoon, or a sharp decline in retail inflows into domestic equities — particularly small and midcap funds. 

On the upside, potential catalysts include a weaker US dollar, which could drive flows into EM funds, and a faster-than-expected private capital expenditure (capex) upcycle. 

Based on feedback from foreign portfolio investors (FPIs), Gupta said Indian equity markets appear somewhat expensive. 

Nevertheless, from a three-to-five year perspective, most foreign investors remain optimistic about India’s medium-term growth outlook. 

FPIs are looking to increase their exposure to Indian stocks once valuations become more attractive. 

However, many EM funds are currently facing redemptions. 

“Capital is flowing back to the US, partly due to a strong dollar and Trump’s policies. Even if India is attractive, FPIs currently lack the funds to invest, as money is being redirected to the US,” Gupta said.

He also pointed out that the capital gains tax has further dampened the appeal of Indian equities for FPIs. 

“Over the past two years, most FPIs achieved around 20 per cent returns in rupee terms, with the rupee remaining relatively stable. After accounting for a 10 per cent long-term capital gains tax (for holdings over a year), returns were still attractive compared to US bond yields.  

However, with bond yields rising, return expectations from India declining, the rupee depreciating by 3-4 per cent, and higher capital gains taxes, FPIs are now left with 6.5-7.5 per cent dollar returns after deductions, taxes, surcharges, and fund manager fees. This is relatively low for an emerging market like India,” Gupta added.

On the domestic front, Gupta noted that while equity inflows into local mutual funds, insurance, and portfolio management services (PMS) have slowed, overall net inflows remain positive. 

“However, the nature of these flows has shifted. Previously, investments were directed towards small and midcap or thematic funds. But now, they are increasingly favouring largecap or balanced debt-equity funds,” he said. 

In terms of sectoral preferences, Kotak Institutional Equities continues to favour large private banks, non-banking financial companies (NBFCs), life insurance firms, residential real estate, hotels, and the airlines/hospitality sectors. 

Conversely, the brokerage remains cautious on consumer staples, discretionary stocks, and the oil & gas and chemicals sectors.

Zara shuts flagship South Mumbai store, new tenant Purple Style Labs to pay rent of ₹10 lakh a day

Zara has shut its only independent store in the 118-year-old heritage Ismail building at Flora Fountain, South Mumbai. Luxury fashion brand Purple Style Labs has now leased 60,000 sq ft of retail space in the same iconic building for an annual rent of ₹36 crore, securing a five-year lease, as per property registration documents obtained by Propstack.com.

According to property registration documents, the new tenant has taken the space on a five-year lease. The rent for five years works out to be ₹206 crore. ₹10 lakh is the daily rent, as per documents.

Purple Style Labs, founded by Abhishek Agarwal in 2015, retails high-end designer brands under Pernia’s Pop-Up Shop brand.

The firm acquired Pernia’s Pop-Up Shop in 2018. It incubates young designer brands and helps them with sales, marketing, and technical support. According to the company’s website, it sells products of renowned labels such as Tarun Tahiliani, Falguni Shane Peacock, Amit Aggarwal, Gaurav Gupta, Seema Gujral, Abhinav Mishra, Shyamal & Bhumika.

In 2020, the company acquired Wendell Rodricks’s brand after the Goa-based designer suddenly passed away at 59.

According to Purple Style Labs’ official website, it currently has stores in several areas of Mumbai, such as Kemps Corner, Juhu, and Bandra.

PSL Retail Private Limited leases 60,000 sq ft of retail space

Purple Style Labs, a luxury fashion chain, has taken 59,350 sq ft of retail space on lease in the Ismail Building for five years. The monthly rent for the store is ₹3 crore, which translates to ₹36 crore annual rent for the first year.

The annual rent for the second year goes up to ₹39 crore, for the third year to ₹42 crore, for the fourth year to ₹43.8 crore, and for the fifth year to ₹45.6 crore, the documents show.

The deposit for the transaction is ₹18 crore, as shown in the documents.

The transaction was registered on December 23, 2025, for which a stamp duty of over ₹53 lakh and registration fees of ₹1,000 were paid.

Zara exits from South Mumbai

Spanish retail brand Zara closed its flagship store in South Mumbai’s Fort area after nine years. The 51,300 sq ft store was located in the Edwardian neoclassical Ismail Building at Flora Fountain.

“Please be informed that this Zara store will cease operations after the end of business on February 23. We will continue to assist you at all our Zara stores in Mumbai,” read a notice outside the Zara store in South Mumbai.

Zara registered the lease for the South Mumbai store in the Ismail Building on April 1, 2016, for a tenure of 21 years. However, property registration documents show that the company decided to close the store after nine years.

The documents showed that Zara paid ₹2.25 crore as rent when it took up the space in 2016 and a deposit of ₹13.5 crore for the 47,565 sq ft space that it leased.

It should be noted that Zara is owned by Inditex SA, a global fashion retailer that has been operating in India since 2010 through a 65:35 joint venture with the Tata Group Trent. It is known as Inditex Trent Retail India. It retails two brands, Zara and Massimo Dutti, in India.

According to Zara’s official website, the company continues to have Zara stores in several other locations in Mumbai. These include the store at Palladium Mall in Lower Parel, Phoenix Market City in Kurla, Oberoi Mall in Goregaon, Infinity 2 Mall in Malad, and Viviana Mall in Thane.

Why did Zara exit South Mumbai?

According to retail experts, a store’s success is not solely determined by its location; financial viability and foot traffic play a significant role.

“Nine years is a reasonable period to assess whether the store is financially sustainable in South Mumbai or if the company can rely on its Palladium Mall location,” a retail head from an international property consultancy told HT.com.

“The South Mumbai demographic that can afford Zara has largely shifted to Central Mumbai, particularly in Worli and Lower Parel, where they are likely shopping at Palladium Mall. As a result, South Mumbai has become just another address, while Palladium Mall offers the advantage of higher foot traffic,” the expert added.

Meanwhile, Arif Fazlani, managing director of the Fazlani Group, which owns the historical building, confirmed Zara’s exit from the Fort area. “Zara will hand over the premises by the end of this month, and starting March 1, there will be a new tenant,” he told Hindustan Times on February 24.

An email query has been sent to Purple Style Labs, but there has been no response. If a response is received, the story will be updated. Zara could not be reached for comment.

Tata Capital IPO: Tata Investment Corporation surges 10%; key things you need to know

Tata Capital IPO: Shares of Tata Investment Corporation (TICL) surged as much as 10.3% to ₹6,343.80 apiece on the BSE on Tuesday, February 25, as Tata Capital, in its regulatory filing available on the BSE, said that the company’s board has given a go-ahead for its initial public offering (IPO).

Tata Capital said that the board of directors of the company has approved the initial public offering (IPO) of the equity shares of face value of ₹10 each comprising the following:

  • a fresh issue of up to 23,00,00,000 (twenty three crore) equity shares; and
  • an offer for sale (OFS) of equity shares by certain existing and eligible shareholders of the company, subject to market conditions, receipt of applicable approvals, regulatory clearances, and other relevant considerations.

Besides IPO approval, the company’s board also gave its nod for the issuance of equity shares of the face value of ₹10 each of the company for an aggregate amount not exceeding ₹1,504 crore on a rights basis to the existing equity shareholders of the company as of the record date, i.e., February 25, 2025.

Tata Investment Corporation (TICL) is one of the largest shareholders of Tata Sons, the holding company for Tata Capital.

In December, the reports of the Tata Capital IPO first surfaced.

According to a report by Moneycontrol in December, Tata Group has initiated work on the IPO of the group’s flagship financial services arm, Tata Capital.

As regards the Tata Capital IPO, the report said, “Work has begun on the proposed initial public offering. This is to comply with RBI’s norms for ‘upper layer’ NBFCs. No final call has been taken on the quantum, but the deal is expected to be a big-bang one over ₹15,000 crore.”

Based on this, Tata Capital’s IPO would exceed the $1.5 billion that LG Electronics Inc.’s Indian unit has been said to be seeking for going public, possibly making Tata Capital the country’s biggest such deal this year, Bloomberg reports.

In October 2024, the Reserve Bank of India (RBI) approved the merger of Tata Capital, an unlisted entity, with Tata Motors Finance (TMFL), paving the way for the formation of India’s 12th largest non-banking finance company.

The RBI sent its “no-objection” to both companies earlier in October, according to the companies’ regulatory filings.

“The RBI’s approval is crucial for the company, which is expected to list its shares by September next year, following an earlier mandate from the regulator that requires all non-banking financial companies classified as upper layer to list their shares by September 2025,” said a Business Standard report dated October 14, 2024.

About Tata Capital

Tata Capital is the flagship financial services company of the Tata Group. It is a subsidiary of Tata Sons and is carrying on business as a non-banking financial company.

Tata Capital and its subsidiaries are engaged in providing/supplying a wide array of services/products in the financial services sector and operate across various areas of business: Commercial Finance, Consumer Loans, Wealth Services, and the distribution and marketing of Tata Cards.

Recent IPOs from Tata Group

Tata Technologies, an arm of Tata Motors, made a terrific debut in the secondary market in 2023. The stock was listed on the stock exchanges on November 30, 2023, with a massive premium of 140% against the issue price of ₹500.

The public issue had a price band of ₹475-₹500 per share. Tata Technologies’ public issue was entirely an offer for sale (OFS) of 6.08 crore equity shares.

The public issue was overall subscribed 69.43 times.

Tata Technologies was the first company from the Tata Group to float an initial public offer (IPO) in nearly two decades, as Tata Consultancy Services (TCS) was the last IPO from the conglomerate in 2004.

Tata Investment Corporation share price trend

Shares of Tata Investment Corporation have fallen over 12% in the past 12 months; however, in the past five years, the stock price has zoomed 580%. 

Tata Investment Corporation has been rated by CRISIL since 1994 and has been assigned their highest rating of ‘AAA’ (pronounced triple A), representing the highest safety in payment of interest and principal amount, whose rating has been reaffirmed from year to year and is valid to date.

TICL acquired a 95.57% stake in Simto Investment Co. Ltd. (Simto) on August 31, 2012, following which Simto became a subsidiary of TICL, per the company’s website.
