In Q4 FY26, the worst quarter for Indian equities in recent memory, promoters of at least 20 Nifty500 companies bought their own stocks in the open market, deploying approximately $4 billion (roughly ₹33,000 crore) even as the BSE Sensex crashed 15.57% and the Nifty50 dropped 14.53%, according to data from Ace Equity and Prime Database. The buying spanned some of India’s largest conglomerates: Adani Group, Aditya Birla Group, and UltraTech Cement. The Q4 FY26 selloff was triggered in March by US and Israeli strikes on Iran, which sent geopolitical risk premiums surging across global markets.
The Scale of the Selloff — and the Buying
In Q4, the 30-share BSE Sensex crashed 13,273 points, or 15.57%, while the Nifty50 dropped 14.53%, or 3,798 points, from the December 31 closing of 26,130. It was the worst quarterly decline in both indices in years.
Against that backdrop, promoter buying stands out not just as a vote of confidence but as a capital commitment made at maximum market stress. Open market trades totalled ₹1.1 trillion in the January–April 2026 period, up 25% from ₹86,810 crore a year ago, according to Prime Database making this the second-highest January–April period for bulk and block deal volumes since at least 2021. A significant portion of that activity was promoter-driven, occurring precisely when benchmark indices were at quarterly lows.
Who Bought and How Much
Adani Energy Solutions saw its promoters raise their stake to 72.73% at the end of the March quarter from 71.19% in December and from 69.94% a year ago. That is a 1.54 percentage point increase in a single quarter, representing hundreds of crores deployed in open market purchases during a period when the broader Adani Group was already under investor scrutiny.
Adani Enterprises, the group flagship, saw promoter stake rise to 74.67% from 73.97% in December. On the Aditya Birla side, Grasim Industries’ promoter holding rose to 43.74% at the end of March from 43.22% in December. UltraTech Cement, India’s largest cement maker, which crossed 200 million tonnes per annum capacity during the quarter, saw its promoters raise their stake to 59.33% from 59.29%.
Beyond the headline names, the list includes NCC, Vardhman Textiles, Saregama India, UPL, HEG, Kalpataru Projects, Jindal Stainless, IRB Infrastructure, Lodha Developers, Kalyan Jewellers, and Paradeep Phosphates, a cross-sector spread that rules out a sector-specific thesis and points to a broader conviction that Q4 valuations were disconnected from fundamentals.
Why Promoters Buy During a Crash — and Why It Matters
Promoter buying during a correction is structurally different from institutional buying. Promoters have full access to unpublished financial results, order pipelines, and forward guidance. They are subject to SEBI’s insider trading regulations, which means they can only buy during designated trading windows when material non-public information is not in play. When they choose to deploy capital in that window, during a 15% index correction, it is the clearest possible signal of internal confidence in business trajectory.
According to analysts cited by Upstox, promoters raising stakes generally indicates positive sentiment toward the business since promoters are aware of the company’s actual financials, growth rate, and product demand.
The counter-signal also matters. A JM Financial report tracking companies with market cap above ₹4,500 crore and stake changes above 0.5% found that a significantly higher proportion of promoters were selling than buying in Q2 FY26, leading to the conclusion that many promoters viewed the market as expensive at that point. The Q4 FY26 reversal, from selling at highs to buying at lows, is the more meaningful data point for long-term investors.
The Open Market Context
The 2026 January–April value of bulk and block deals is the second-highest since at least 2021, though 2024 remains an outlier at ₹2.15 trillion, primarily driven by British American Tobacco’s ₹17,500 crore divestment in ITC, Rakesh Gangwal’s ₹6,800 crore stake sale in InterGlobe Aviation, and Singtel’s ₹5,800 crore divestment in Bharti Airtel.
Deven R. Choksey, founder of DRChoksey FinServ, described the current period as “a clear rotation of capital” in which fundamentally strong companies are absorbing large supply without breaking technical support levels. He noted that “the market has successfully absorbed over ₹1 trillion of supply while continuing to hold key technical support levels.”
What It Does Not Mean
Promoter buying is a signal, not a guarantee. In Q4 FY26, several companies on the buying list also reported margin pressure or weaker-than-expected earnings. Maruti Suzuki is the clearest example: promoters raised their stake to 53.53% even as Q4 net profit fell 6.4% to ₹3,659 crore despite record revenue of ₹52,462 crore. The stake increase reflects long-term conviction; it does not insulate the stock from short-term earnings-driven selling.
Additionally, not all stake increases are open market purchases. Some are the result of buyback participation, conversion of warrants, or inter-promoter transfers. Investors should check the specific transaction mode in BSE/NSE shareholding disclosures before interpreting any individual stake change as a market buy.

Frequently Asked Questions
1. Which promoters bought their own stocks in Q4 FY26?
At least 20 Nifty500 company promoters raised stakes in Q4 FY26, per Ace Equity data. The most prominent names include Adani Energy Solutions (stake up to 72.73%), Adani Enterprises (up to 74.67%), Grasim Industries (up to 43.74%), and UltraTech Cement (up to 59.33%). Others include NCC, Lodha Developers, Kalyan Jewellers, IRB Infrastructure, and Vardhman Textiles.
2. How much did promoters spend buying their own stocks in Q4 FY26?
Approximately $4 billion (roughly ₹33,000 crore) in aggregate, according to the Economic Times, during a quarter when the Sensex fell 15.57% and the Nifty dropped 14.53% from December 31 levels.
3. Why does promoter buying matter to investors?
Promoters have the most complete picture of a company’s financial health and growth pipeline. Under SEBI insider trading rules, they can only buy in designated trading windows when material non-public information is not active. A decision to deploy significant capital during a 15% market correction signals strong internal conviction about business fundamentals, more credibly than analyst upgrades or institutional buying.
4. Does promoter buying mean the stock will go up?
Not necessarily. Maruti Suzuki promoters raised their stake in Q4 FY26 even as quarterly profit fell 6.4%. Promoter buying reflects long-term conviction, not a short-term price call. It should be one signal among several, not a standalone buy trigger. Always verify whether a stake increase was an open market purchase or a technical transfer.
5. Which sectors saw the most promoter buying in Q4 FY26?
The buying was cross-sectoral, energy (Adani Energy Solutions), cement (UltraTech, Grasim), infrastructure (NCC, IRB, Kalpataru), real estate (Lodha), textiles (Vardhman), media (Saregama), jewellery (Kalyan), and chemicals (UPL, Paradeep Phosphates). The breadth rules out a sector-specific catalyst and points to a market-wide valuation call.
