In October 2017, SEBI directed AMFI to classify every listed Indian company into Large Cap, Mid Cap or Small Cap — and to revise this list every six months based on average market capitalisation. It sounds like a technical exercise. It is not. Every time the list changes, mutual funds worth crores have to rebalance. Fund managers reshuffle portfolios. Companies that enter Large Cap suddenly attract mandatory investment from every large cap fund in India. Companies that leave it lose that forced buying. This page traces all seventeen AMFI updates from January 2018 to January-June 2026 — the markets that shaped each period, the companies that moved, and what it all means.

Before we begin — a word on the mechanics. SEBI defines the top 100 companies by 6-month average market cap as Large Cap, the next 150 as Mid Cap, and everything else as Small Cap. Mutual funds that call themselves large cap funds must hold at least 80% in these top 100 stocks. Mid cap funds must hold 65% in companies ranked 101 to 250. Small cap funds must hold 65% in companies ranked 251 and beyond. When a company crosses a threshold, funds have exactly one month to comply. This is why category changes matter — they trigger real buying and selling, not just re-labelling.
The first AMFI categorisation list, effective February 2018, set the Large Cap threshold at ₹30,609 crore. To put that in perspective — a company needed to be worth roughly the same as a mid-sized Indian conglomerate just to qualify for the top 100. The Mid Cap cutoff was set at ₹9,984 crore. India's total stock market capitalisation at the time was approximately ₹155 lakh crore, and the list covered 4,887 companies — 100 Large Cap, 150 Mid Cap, and 4,637 Small Cap. This was the baseline. Every SEBI stock category change since has been measured against it.
What most investors did not appreciate in early 2018 was how much this single regulatory change would reshape mutual fund portfolio construction. Before SEBI's October 2017 circular, a fund manager could call his fund "large cap" and fill it with mid cap stocks. After the circular, that was no longer possible. The categorisation enforced discipline — and that discipline created predictable patterns. When a company enters Large Cap, large cap funds must buy. When it exits, they must sell. The list became a source of structural demand and supply.
Even in a falling market, quality businesses earned their promotions. Divi's Laboratories entered Large Cap — a pharma API manufacturer that had been compounding quietly for years, supplying bulk drugs to global innovator companies. Its business model — making the molecules that pharma giants need but don't want to make themselves — is defensible, capital-efficient, and nearly invisible to the average investor. Its entry into Large Cap was well earned. Berger Paints entered as well, representing the steady consumer franchise that holds value in credit-tight environments. Paint is a necessity — homes get painted regardless of what NBFCs are doing. United Breweries entered on similar logic — India's alcohol consumption story has its own resilient demand drivers.
On the downside, eight companies left Large Cap. The exits were concentrated in two themes: NBFCs (which were at the epicentre of the IL&FS crisis) and defence PSUs (which were caught in the broad October sell-off rather than any fundamental change). Bharat Electronics (BEL) and Hindustan Aeronautics (HAL) both dropped despite having strong order books and government backing — a reminder that in a panic, markets sell what they can, not just what deserves selling. Both would return to Large Cap in subsequent periods.
| Entered Large Cap — Jul-Dec 2018 | Left Large Cap — Jul-Dec 2018 |
|---|---|
| ↑ Divi's Laboratories | ↓ Sun TV Network |
| ↑ United Breweries | ↓ Bharat Electronics (BEL) |
| ↑ Berger Paints | ↓ HAL |
| ↑ GlaxoSmithKline Consumer | ↓ Aditya Birla Capital |
| ↑ Page Industries | ↓ Bharat Forge |
In the Small Cap space, a quiet but significant promotion happened. Solar Industries India — a Nagpur-based manufacturer of industrial explosives — entered Mid Cap at ₹9,850 crore. The company supplied explosives to mining companies, quarries, and infrastructure projects. Its moat was both regulatory (explosives manufacturing requires extensive licensing) and geographic (customers need reliable local supply). At the time, almost no mutual fund analyst had Solar Industries on their coverage list. By 2025, it would be a Large Cap company worth ₹1,27,239 crore — a 12.9x journey that started here, quietly, in this period.
The January–June 2019 AMFI update carried a development that deserved more attention than it received. Yes Bank fell from Large Cap to Mid Cap for the first time. At its peak in 2017-18, Yes Bank had been one of India's fastest-growing private sector banks — expanding aggressively, funding real estate developers and infrastructure companies, growing deposits at 30%+ annually. Its fall to Mid Cap was dismissed by many as a routine threshold adjustment. In hindsight, it was the first visible sign of the asset quality stress that was building beneath the surface. Indiabulls Housing Finance also fell in this period — housing finance NBFCs were feeling the credit freeze from IL&FS. Power Finance Corporation entered Large Cap on the other side, reflecting the market's preference for PSU lenders seen as more stable than their private counterparts.
While the physical economy was slowing, India's digital economy was quietly achieving scale. Info Edge — the company behind Naukri.com, 99acres.com, Jeevansathi.com, and an early investor in Zomato when it was still a tiny startup — entered Large Cap. This was significant. Info Edge was not a glamorous IPO or a high-profile listing. It had been building India's internet classifieds ecosystem for two decades. Its entry into Large Cap was the market acknowledging that India's internet economy had moved beyond the experimental phase. Muthoot Finance also entered — gold loans tend to grow precisely when formal credit tightens, as borrowers turn to their most reliable asset. The company's expansion during the NBFC crisis was counter-cyclical and powerful.
Vodafone Idea fell from Large Cap in this period as the Supreme Court's AGR ruling placed a substantial financial burden on the company. Yes Bank continued its descent — falling for the second consecutive period, with each successive update making its situation harder to dismiss as temporary.
| Entered Large Cap — Jul-Dec 2019 | Left Large Cap — Jul-Dec 2019 |
|---|---|
| ↑ Info Edge (India) | ↓ Yes Bank |
| ↑ Adani Transmission | ↓ Vodafone Idea |
| ↑ Muthoot Finance | ↓ Cadila Healthcare |
| ↑ REC Limited | ↓ Indiabulls Housing Finance |
The Large Cap threshold fell just 1.5% — a remarkably small move given the severity of what had happened. The Mid Cap threshold, however, fell 15.6% — revealing how much harder the smaller companies were hit by the sudden credit and liquidity freeze. With no revenue, no collections, and no clarity on when normalcy would return, mid-sized companies were far more vulnerable than their large cap counterparts. Large cap companies had the balance sheets, the banking relationships, and the brand equity to weather the storm. Mid cap companies were far more exposed.
Pharma was the standout sector. Three pharma companies entered Large Cap in this period: Cadila Healthcare (returning after a brief exit), Alkem Laboratories, and Abbott India. The pandemic had permanently elevated the profile of Indian pharmaceutical manufacturing. India was — and remains — the pharmacy of the world in generic drugs. The country manufactures 60% of the world's vaccines, 20% of generic medicines, and supplies medicines to 200+ countries. The market was simply acknowledging what had always been true: this is a strategic national industry, and the companies in it deserve premium valuations.
The second half of 2020 produced one of the most astonishing market recoveries in global financial history. The Nifty surged from 10,302 in June to 13,981 by December — a 36% gain in six months. Three forces converged: global central banks flooded the world with unprecedented liquidity, India's own government and RBI provided fiscal and monetary support, and — uniquely Indian — a new generation of retail investors arrived. With no cricket to watch, no movies to see, and stock markets accessible from a mobile phone for the first time at scale, millions of young Indians opened demat accounts. Monthly new demat account openings went from 4 lakh pre-Covid to 26 lakh. These were not speculators — many were first-time long-term investors who would stay in the market for years.
The Mid Cap threshold surged 20.6% in this single six-month period — the second largest jump in our eight-year story. Jubilant Foodworks (Domino's India) entered Large Cap as home delivery became not just convenient but the only option during lockdowns. Adani Enterprises entered Large Cap — the holding company of a group that was about to embark on the most ambitious corporate expansion in Indian market history. HAL returned as India's defence manufacturing priorities accelerated. Each of these entries reflected a genuine business development, not just a market re-rating.
| Entered Large Cap — Jul-Dec 2020 | Category before |
|---|---|
| Jubilant Foodworks (Domino's India) | Mid Cap |
| Adani Enterprises | Mid Cap |
| HAL | Mid Cap |
| PI Industries | Mid Cap |
In August 2020 — in the depths of Covid uncertainty — Tube Investments of India, part of the 125-year-old Murugappa Group, acquired a controlling stake in CG Power and Industrial Solutions for approximately ₹700 crore. CG Power had faced serious financial difficulties and required a complete leadership and governance overhaul. What Murugappa saw was the underlying business: a company making industrial motors, switchgear, and transformers with relationships built over 130 years with India's power utilities and industrial customers. Banks agreed to restructure their exposure. The turnaround began quietly, in the worst year of the decade. By December 2024, CG Power entered Large Cap with a market cap of ₹1,10,189 crore — 22.1x its January 2018 value. It is one of the finest corporate turnarounds in Indian market history.
The Mid Cap threshold surged 40.9% in a single six-month period — the single largest jump in our entire eight-year story. This produced a counterintuitive outcome: many excellent businesses fell from the Large Cap list not because they deteriorated, but because they grew more slowly than the market as a whole. Abbott India, Alkem Laboratories, and Petronet LNG — all profitable, dividend-paying, fundamentally sound companies — fell from Large Cap simply because the threshold surged past their market caps. This is one of the most important lessons in the SEBI categorisation data: a downgrade is not always bad news. Sometimes it is just mathematics.
Apollo Hospitals entered Large Cap — healthcare had been permanently re-rated after Covid. The investment in quality hospitals that India had been deferring for decades was now happening urgently. Adani Total Gas entered as city gas distribution scaled rapidly across Indian cities. Bank of Baroda entered — PSU banks, which had been largely ignored by the market for a decade due to NPA concerns, were beginning to attract attention as their balance sheets cleaned up.
The second half of 2021 was the peak of the bull cycle. The Nifty crossed 18,000 in October, Sensex touched 62,000. A wave of high-profile IPOs hit the market — Zomato, Paytm, Nykaa, PolicyBazaar all listed in FY22, raising over ₹1.2 lakh crore combined. The Large Cap threshold surged another 26.5%. Godrej Properties entered as real estate staged its strongest recovery in nearly a decade — not just in prices but in volumes. Mindtree and Mphasis entered as IT services companies rode a global wave of digital transformation spending. Every enterprise in the world was rebuilding its technology stack, and India's IT services companies were the primary beneficiaries. SRF Limited and Bharat Electronics also entered — specialty chemicals and defence were becoming serious investor themes.
This period saw 32 Large Cap downgrades — the highest in any single period across all eight years. Lupin, Biocon, Bandhan Bank, Aurobindo Pharma, Bosch — all established businesses with strong fundamentals — fell from Large Cap because the threshold rose faster than their market caps. The bull market of 2021 was extraordinarily selective: it rewarded IT, real estate, Adani infrastructure, and new-economy businesses. It was indifferent to pharma, certain banks, and traditional manufacturing. Category changes in this period were not verdicts on business quality — they were reflections of where market enthusiasm was concentrated.
| Entered Large Cap — Jul-Dec 2021 | Left Large Cap — Jul-Dec 2021 |
|---|---|
| ↑ Godrej Properties | ↓ Lupin |
| ↑ SRF Limited | ↓ Biocon |
| ↑ Bharat Electronics | ↓ Bandhan Bank |
| ↑ Mindtree | ↓ Aurobindo Pharma |
| ↑ Mphasis | ↓ Bosch |
The first half of 2022 saw FIIs sell ₹1.4 lakh crore of Indian equities — a significant outflow driven by US rate hikes making dollar assets more attractive. Yet the market held, because domestic institutional investors (DIIs) and retail investors absorbed the selling. For the first time in India's market history, domestic flows were large enough to counter foreign outflows. The SEBI categorisation changes of 2022 reflected this resilience.
Adani Power entered Large Cap in the January–June 2022 update, benefiting from a global energy context where coal-based power generation was being re-evaluated. Cholamandalam Investment and Finance entered — the vehicle finance and home loan NBFC had navigated the 2018-19 NBFC crisis carefully and emerged as a dominant, trusted player. In the July–December 2022 recovery, Varun Beverages entered Large Cap — the Pepsi franchise company had been growing at 25%+ annually by adding new territories, new products (energy drinks, dairy), and new distribution channels. Tata Elxsi entered as the global EV transition created insatiable demand for automotive software and electronics design.
To understand the significance of this threshold movement: in January 2018, the Large Cap cutoff was ₹30,609 crore. By December 2023, it was ₹67,018 crore — more than double in five years. A company that was comfortably Large Cap in 2018 needed to more than double its market cap just to retain the same rank by 2023. This is what India's economic growth looked like from the inside of the categorisation data — not as GDP percentages or index points, but as real company valuations.
The PSU bank story of 2022-23 is one of the most dramatic reversals in Indian market history. Between 2014 and 2020, public sector banks were widely viewed as troubled institutions — burdened by non-performing assets from reckless lending to infrastructure projects and corporate groups in the previous decade. Their stocks were cheap for years. Then the cleanup happened. The government provided capital. RBI's asset quality review forced recognition of bad loans, which paradoxically led to cleaner balance sheets over time. By 2022-23, PSU banks were reporting their strongest earnings in a decade. Canara Bank, IDBI Bank, Union Bank of India, and Indian Overseas Bank all entered Large Cap in successive updates — the market rewarding a transformation that had taken years of painful work to achieve.
Shriram Finance entered Large Cap — the merger of Shriram Transport Finance and Shriram City Union Finance had created India's largest NBFC by assets under management, with a dominant position in commercial vehicle financing. Polycab India entered — wires, cables, and electrical products are the unsexy but essential beneficiaries of every infrastructure rupee the government spends. Macrotech (Lodha) entered as Mumbai real estate hit record prices.
| Entered Large Cap — Jul-Dec 2023 | Left Large Cap — Jul-Dec 2023 |
|---|---|
| ↑ Union Bank of India | ↓ Hero MotoCorp |
| ↑ Shriram Finance | ↓ Bosch |
| ↑ Polycab India | ↓ UPL Limited |
| ↑ Macrotech (Lodha) | ↓ Adani Wilmar |
| ↑ Indian Overseas Bank | ↓ Tube Investments |
The July–December 2024 AMFI update crossed a milestone that no one had anticipated when SEBI first published its categorisation list in 2018. The Large Cap threshold reached ₹1,00,119 crore — crossing one lakh crore rupees for the first time. In 2018, that threshold was ₹30,609 crore. In six years, the bar to be called India's 100th largest listed company had risen 3.3x. A company that had been solidly Large Cap in 2018 needed to be more than three times larger in absolute terms just to maintain the same position. This is what compounding economic growth looks like at the national level.
Only 11 companies entered Large Cap in this period versus 24 that were downgraded — the highest ratio of exits to entries in our eight-year story. The threshold had risen so sharply that even quality businesses were being pushed out. IndusInd Bank, Canara Bank, Union Bank, and Shree Cements all fell. Meanwhile, in the Small Cap to Mid Cap space, the January–June 2024 period was particularly active — 15 companies rose from Small Cap to Mid Cap, including BSE Limited (India's oldest stock exchange, finally scaling to Mid Cap size) and Global Health Limited (Medanta hospitals, a reflection of the premium healthcare boom).
In the July–December 2024 AMFI update, CG Power and Industrial Solutions entered Large Cap with a market cap of ₹1,10,189 crore. The journey had begun with a significant financial restructuring in 2019, a strategic acquisition by Tube Investments of India in August 2020 for ₹700 crore, debt elimination by 2022, and then a powerful re-rating as CG Power became a beneficiary of India's electronics manufacturing push — including a semiconductor assembly and testing facility. From a Small Cap company at ₹4,991 crore in January 2018 to a Large Cap company at ₹1,10,189 crore in December 2024. 22.1x in seven years. Patient capital, disciplined management, and India's structural growth story — all three working together.
The January–June 2025 update delivered a historic first. Indian Hotels Company — the custodian of the Taj Hotels brand, founded by Jamsetji Tata in 1903 — entered Large Cap for the very first time in its existence. This was not just a data point. It was a symbol. A company that had been part of India's hospitality landscape for over a century, that had hosted heads of state and survived multiple crises including the 2008 Mumbai attacks, had finally scaled to the point where it ranked among India's top 100 listed companies. The post-Covid travel revival, premium room rate expansion, high occupancy levels, and years of disciplined balance sheet improvement had brought Indian Hotels to this milestone.
Solar Industries India also completed its remarkable journey in this update — entering Large Cap after seven years that began as a Small Cap industrial explosives manufacturer. The Nagpur-based company had grown steadily through infrastructure and mining demand, then accelerated dramatically when India's defence indigenisation programme created massive demand for domestically manufactured explosives, ammunition, and propellants. India's defence export ambitions added another dimension. From ₹9,850 crore in 2018 to ₹1,27,239 crore — 12.9x in seven years — Solar Industries is perhaps the clearest example of a business that did not need a narrative or a rebranding. It simply built a better version of what it had always been, year after year.
Markets recovered through mid-2025 as FII selling moderated. India's domestic consumption remained strong, government spending continued at elevated levels, and corporate earnings delivered. The Large Cap threshold hit a new all-time high of ₹1,05,174 crore. HDFC AMC returned to Large Cap as equity markets stabilised. Muthoot Finance returned — gold finance has proven through multiple cycles that it is a resilient, counter-cyclical business. Canara Bank, Polycab India, and Bosch also returned. The most striking number: 214 new companies were added to the AMFI universe in this single period — the largest addition in seven years. India's IPO market had brought companies from EVs, green energy, defence, semiconductors, and fintech into the public market. The AMFI list, which had 4,887 companies in January 2018, now covered 5,372.
| Entered Large Cap — Jul-Dec 2025 | Left Large Cap — Jul-Dec 2025 |
|---|---|
| ↑ HDFC AMC | ↓ REC Limited |
| ↑ Muthoot Finance | ↓ Shree Cements |
| ↑ Canara Bank | ↓ Mankind Pharma |

The January–June 2026 AMFI update told a story of a market in equilibrium. The Large Cap threshold rose a modest 1.1% — from ₹1,05,174 crore to ₹1,06,346 crore. This near-flat movement reflected a market that had largely priced in the recovery but had not yet broken to new highs. The consequence of a flat threshold is high churn near the boundary: companies clustered just above and just below the cutoff shuffled positions. Nine companies left Large Cap and eight entered — a near-even exchange that kept the Large Cap universe at exactly 100 companies.
The most notable entrant was Groww — operating as Billionbrains Garage Ventures Limited — which entered Large Cap at ₹1,12,113 crore. Groww is the first pure-play retail investing platform to reach Large Cap status in India. Founded in 2016, Groww democratised equity investing for a generation of first-time investors across tier-2 and tier-3 cities, growing to over 10 crore registered users. Its entry into Large Cap is a marker: the infrastructure of India's financial markets — not just the companies that list on them, but the platforms through which retail investors access them — has now scaled to the point of ranking among India's 100 largest listed businesses. BHEL also entered at ₹1,09,929 crore — a remarkable return for a PSU that had been largely written off in earlier years as India's power infrastructure spending stagnated. The energy transition and accelerated power capacity addition changed that narrative entirely.
Nine companies left Large Cap — with the threshold essentially flat, exits were driven by individual stock underperformance rather than a rising bar. Indian Hotels Company — which had entered Large Cap for the very first time in its century-long history just one period earlier in January–June 2025 — fell back to Mid Cap at ₹94,199 crore. This is the categorisation system's most instructive lesson repeated: entry does not mean permanence. A company hovering near the threshold will oscillate across it. Mazagon Dock Shipbuilders, a beneficiary of India's naval expansion, fell to ₹98,569 crore as defence stock valuations moderated from their peaks. Max Healthcare, Lodha Developers, and Dr. Reddy's Laboratories all slipped below the threshold — each for different reasons, none representing a fundamental business failure.
Bosch and Hero MotoCorp also exited — both high-quality businesses with decades of consistent performance. Bosch has now oscillated in and out of Large Cap multiple times across this eight-year dataset, a pattern that reflects its market cap reliably hovering near the boundary rather than any instability in the business. Vodafone Idea entered Large Cap at ₹1,23,358 crore — a reminder that market cap and business health are not the same thing. Vi's inclusion reflects its large equity base and the market's options-like speculation on a potential revival, not a fundamental business turnaround. Jindal Steel and Indian Bank entered as steel demand held firm and PSU banks continued their multi-year earnings recovery. Indus Towers entered as India's telecom infrastructure story proved durable across multiple operator cycles.

Of the 4,887 companies in the January–June 2018 AMFI list, only three classified as Small Cap that year had made the complete journey to Large Cap by January–June 2026. The difficulty is not just business growth — the Large Cap threshold itself grew 3.5x during this period. A company had to not just grow, but outpace a bar that kept rising. These three companies did that — through different businesses, different journeys, and different kinds of patient capital.
In January 2018, Adani Green Energy was a ₹4,543 crore Small Cap company. India had set an audacious target: 500 GW of renewable energy by 2030. Adani Green positioned itself as the primary vehicle for this ambition — securing solar and wind capacity at scale, leveraging the group's land access, financing relationships, and execution track record. It crossed Mid Cap in July–December 2019 and reached Large Cap in January–June 2020. The company navigated a period of significant market scrutiny in early 2023 and emerged with its renewable energy thesis intact and its project pipeline growing. By June 2026, Adani Green remained among India's largest renewable energy operators. 35.9x growth in eight years.
CG Power's story is about the power of good management inheriting a great business. The company, which makes industrial motors, switchgear, transformers, and power electronics, had 130 years of customer relationships, deep technical expertise, and strong brand recognition among India's power utilities. When serious financial difficulties emerged in 2019, requiring a complete governance overhaul, Tube Investments of India — part of the Murugappa Group — stepped in with ₹700 crore in August 2020. The Murugappa Group applied its characteristic discipline: clear leadership, vendor trust rebuilding, talent retention, and financial conservatism. By 2022, debt-free. By 2024, Large Cap. 22.1x in seven years.
Solar Industries is the story that most investors would have been unable to tell you in 2018. An industrial explosives manufacturer in Nagpur. No glamour, no disruptive technology, no famous founder. Just a business that supplies the explosives that mines, quarries, and infrastructure projects need to break rock. The moat is regulatory — explosives manufacturing requires extensive licensing — and geographic — customers need reliable local suppliers who understand their specific requirements. Solar Industries built that moat over decades. Then India's defence indigenisation programme arrived, and everything accelerated. The company began supplying hand grenades, bombs, and propellants under Make in India. Defence revenues grew rapidly. It crossed Large Cap in January–June 2025 — the longest of the three journeys, and perhaps the most instructive. 12.9x in seven years.
The Large Cap threshold grew from ₹30,609 crore in January 2018 to ₹1,06,346 crore in June 2026 — a 3.5x increase in eight years. This is not just an index moving. This is the valuation of real businesses compounding. The company ranked 100th in India by market cap in 2018 was worth ₹30,609 crore. The company ranked 100th in June 2026 was worth ₹1,06,346 crore. The economy beneath those numbers — the revenues, the profits, the employees, the customers — grew with it. India's listed universe expanded from 4,887 companies to 5,427 as new industries brought their companies to the public market: food delivery, electric vehicles, green energy, semiconductors, defence technology, retail investing platforms, and new-age insurance and lending.
Some companies proved to be permanent fixtures — Reliance Industries, HDFC Bank, TCS, Infosys, ICICI Bank, and SBI held their top positions through every bull market and correction, growing steadily as India grew. Others oscillated — Polycab India entered Large Cap, exited, re-entered, exited, and re-entered across multiple periods. Canara Bank entered Large Cap three separate times. Bosch entered and exited more than once. Indian Hotels entered for the first time in its century of existence — and fell back within one period. These oscillations are not a sign of instability — they reflect businesses that hover near the threshold, whose category assignment changes with each six-monthly recalculation of the average market cap. The business can be excellent and the category assignment can still change.
The most enduring lesson from this eight-year dataset: a category change is a mirror, not a verdict. When a company enters Large Cap, it does not become a better business overnight. When it leaves Large Cap, it does not become a worse one. What changes is relative size — how this company's market cap ranks against the other 5,000+ listed companies in India. The category system exists to ensure mutual funds are honest about what they own. It is a compliance tool that, as a side effect, tells us a great deal about how India's economy has grown and which industries the market has chosen to value most highly at each point in time.
