Nifty Microcap 250 Index: Constituents, Levels and Tax for Indian Traders

What the Nifty Microcap 250 Actually Is

The Nifty Microcap 250 is the only NSE index built purely from microcap stocks, the smallest listed companies that still meet basic liquidity rules. NSE Indices builds it from companies that sit below the Nifty 500. In plain terms, the Nifty 500 captures the 500 biggest companies, and the Microcap 250 picks the next slice down, roughly the 501st to 750th by full market value. These are firms with market caps often in the few hundred to few thousand crore range, far smaller than a Reliance or an HDFC Bank.

The index started at a base value of 1,000 on 1 April 2005. Because microcaps have run hard in bull phases, it has multiplied many times since and by mid 2026 trades in the 25,000 to 30,000 zone on a total market basis. These figures are illustrative and move every day, so treat the live print on the NSE Indices site as the only number that matters for a real decision. It is calculated on a free float market capitalisation method, so only publicly available shares, not promoter locked holdings, count toward each company's weight.

Note the difference between the price return and total return versions of the index. The price return index ignores dividends, while the total return index reinvests them. When you judge a fund against the benchmark, compare it against the total return index, otherwise the fund looks like it is beating the market when it is simply collecting dividends the price index leaves out.

Real Constituents You Will Find Inside

Generic guides describe microcaps in the abstract. To make it concrete, here are real companies that have featured in or around the Nifty Microcap 250 in recent rebalances: pipe and engineering maker Jindal Saw, real estate developer Brigade Enterprises, holding company Sundaram Finance Holdings, lubricants maker Castrol India, turbine maker Triveni Turbine, IT distributor Redington, and tyre maker JK Tyre and Industries. You will also find many chemical, textile, capital goods and regional bank names that large cap investors never track.

Because there are 250 names, no single stock dominates. Top holdings carry only around 1% to 2% each, unlike the Nifty 50 where the top names run 8% to 10% apiece. That flat weighting gives genuine breadth, but it means a few winners cannot rescue you if the broad microcap tide goes out. Sector wise the index leans toward capital goods, chemicals, financials and industrials, with little of the IT and consumer heavyweights that anchor large cap indices.

How a Stock Earns Its Place

Membership is rules based, not discretionary. A company must first be in the eligible universe: listed, traded for a reasonable period, and clearing minimum trading frequency and impact cost thresholds so the index is investable rather than full of stocks nobody can buy. NSE Indices then ranks that universe by full market capitalisation, and the names ranked below the Nifty 500 cut off, down to roughly rank 750, form the Microcap 250 pool.

• The stock must be in the eligible universe and traded for a defined minimum period before inclusion.
• It must clear liquidity filters on impact cost and trading frequency, so illiquid shells are kept out.
• Ranking is by full market capitalisation, but each stock's weight inside the index is by free float market capitalisation.
• Single stock weights are capped at rebalancing so no microcap can balloon the index, which is refreshed semi annually.

This tells you the index is a momentum tilted, survivorship cleaned basket. Stocks that crash and lose liquidity fall out at the next review, and stocks that surge graduate upward and also leave. The index you see today is partly a record of which microcaps stayed liquid and grew, not a static museum of the same 250 firms. That is why its long term chart looks smoother than the ride any single underlying microcap delivered.

Why There Are No Futures or Options Here

An important fact for derivatives traders: the Nifty Microcap 250 has no listed futures or options. The NSE offers index F&O only on a few highly liquid benchmarks such as Nifty 50 (lot size 65), Bank Nifty (lot size 30) and FinNifty (lot size 60). Microcap derivatives would be impossible to hedge because the underlying shares are too thin for market makers to lay off risk. So you cannot buy a Microcap 250 call the way you buy a Nifty weekly call.

Instead you get exposure through a passive index fund or ETF that replicates the Microcap 250, the best known being the Motilal Oswal Nifty Microcap 250 Index Fund, or by buying the underlying shares yourself. Both are cash market, delivery based trades. That changes the tax and cost picture entirely versus F&O, which is why the worked example below uses a delivery trade.

A Fully Worked Example With Real Rupees

Here is a realistic, illustrative trade. Suppose on 1 June 2025 the Nifty Microcap 250 Total Return Index is at 25,000 and you invest Rs 5,00,000 in a fund tracking it, buying units at a notional Rs 25 each. That gives you 20,000 units. This is a buy and hold cash trade, so costs are delivery costs, not F&O costs. Numbers are for illustration only, never a promise of returns.

Assume over the next 14 months the index rises 20% to 30,000, so each unit is worth Rs 30 and your holding is worth Rs 6,00,000. Because you held more than 12 months, the gain is a long term capital gain of Rs 1,00,000. Now apply the costs and tax honestly.

Notice what happened. Because your long term gain of about Rs 99,200 sits below the Rs 1.25 lakh annual LTCG exemption, you pay zero capital gains tax, only the small STT and brokerage. Now flip it. If you had sold within 12 months, the entire Rs 1,00,000 would be a short term gain taxed at 20%, that is Rs 20,000 of tax, leaving roughly Rs 79,200. Holding past the one year mark saved about Rs 20,000 here. That is the practical power of knowing the rules before you click sell.

How Microcaps Are Taxed in India

Getting tax right is where many microcap investors quietly lose money. For listed equity and equity index funds bought on a recognised exchange, the 2026 rules are clear. A holding sold within 12 months is a short term gain taxed at a flat 20%. A holding sold after 12 months is a long term gain, and the first Rs 1.25 lakh of such gains across all your equity in a financial year is exempt. Anything above is taxed at 12.5% without indexation. These replaced the older 15% and 10% figures, so any guide still quoting those is out of date.

If you instead actively trade microcaps at high frequency, intraday or as a main income, the tax department may treat your profits as business income, taxed at your slab rate. That can be higher, but it lets you deduct expenses such as brokerage, internet, advisory fees and depreciation. It is the same principle that makes F&O gains always business income. Which bucket you fall into depends on volume, frequency and intent, so let a chartered accountant decide your case.

• Held under 12 months and treated as investment: STCG at 20%.
• Held over 12 months and treated as investment: LTCG at 12.5% on gains above Rs 1.25 lakh per year, nil below it.
• Frequent or intraday activity treated as business: taxed at your income slab, with expenses deductible.
• STT applies on every delivery buy and sell at 0.1% of value, and is a cost you cannot reclaim.
• Keep contract notes and a ledger so your return matches your broker's tax profit and loss statement.

The Risks You Cannot Ignore

Microcaps carry risks that barely exist at large cap level. Liquidity is the first. Many constituents trade only a few crore of shares a day, so a single large seller can drop the price several percent, and your stop loss may execute far below where you placed it. Impact cost, the gap between the price you want and what you actually get, is high. Information gaps are the second: these companies get little analyst coverage, so prices lag fundamentals and rumours move stocks more than facts.

The third risk is drawdown depth. In sharp corrections the microcap segment falls harder and recovers slower than the Nifty 50. A 25% Nifty fall can pair with a 40% or worse fall in microcaps. SEBI has repeatedly flagged froth in small and microcap names and pushed mutual funds to stress test their small and midcap schemes, a reminder that regulators view this corner as a place where retail money can get hurt fast. Treat any single microcap position as something you could lose most of, and size it accordingly.

Sensible Ways to Get Exposure

For most people the cleanest route is a passive index fund that mirrors the Microcap 250. You get all 250 names in one purchase, professional rebalancing at each review, and no need to read balance sheets. The trade off is a small expense ratio and riding the whole segment down in a bear phase. Treat it as a satellite holding, a small slice bolted onto a core of large cap and index funds, not the centre of your portfolio.

If you prefer picking individual stocks, do it with eyes open. Read the annual report, check promoter pledging, see whether profits convert into real cash flow, and avoid names where the only story is a rising chart. Spread across several positions rather than betting everything on one, and write down your sell rule before you buy. Traders who survive this segment treat each microcap as a small, defined risk, not a lottery ticket.

• Use a Microcap 250 index fund for hands off, diversified exposure, capped at a small share of your portfolio.
• If picking stocks, demand real cash flows and low promoter pledging, not just a rising price.
• Never average down into a falling microcap on hope, the liquidity may not let you exit later.
• Compare any fund against the total return index, not the price index, so dividends count fairly.
• Keep a written journal of entry reason, stop and target to review what actually worked.

Microcap 250 Versus Smallcap and Largecap

It helps to place the Microcap 250 next to its neighbours so you know exactly what you are buying. The table below compares the three broad tiers on the traits that actually affect your trading, using rounded, illustrative figures. Confirm current constituent counts and weights on the official factsheets, as they are revised at every rebalance.

The pattern is consistent. As you move from large to micro, the potential reward in a bull run rises, but so does liquidity risk, drawdown depth and the chance a single bad event wipes out a position. The Microcap 250 belongs at the aggressive end of a portfolio, sized small, never the foundation. Used that way it can add real upside. As a core holding it can hand you losses that take years to recover.

Where to Verify Every Number

Index levels, constituent lists and weights change, and finance content goes stale quickly. Before you trade, confirm the live index level and download the current factsheet and methodology from NSE Indices at niftyindices.com. Check market rules and investor advisories at sebi.gov.in, and verify a stock's data on nseindia.com. The tax rates above are current as of 2026, but confirm with the latest Finance Act and a chartered accountant for your own situation.
