Nifty Smallcap 100 Index: Constituents, ETFs and How to Trade It

What the Nifty Smallcap 100 Actually Is

The Nifty Smallcap 100 is an index built and maintained by NSE Indices Limited, a subsidiary of the National Stock Exchange. It tracks 100 companies drawn from the smallcap slice of the listed market. In NSE methodology, the largest 100 companies by full market capitalisation form the largecap band, the next 150 form the midcap band, and companies ranked beyond 250 fall into the smallcap band. The Nifty Smallcap 100 picks 100 names from that smallcap pool, broadly the companies ranked from about 251 to 500 in the eligible universe, subject to liquidity and trading frequency filters.

It is a free float market capitalisation weighted index. That means each company's weight depends on the value of shares actually available to public trading, not on promoter or locked in holdings. The base date is 1 January 2004 with a base value of 1,000. Because the constituents are small companies, a handful of names can move sharply in a single session, which is why the index is far more volatile than the Nifty 50.

One important clarification many guides get wrong. The Nifty Smallcap 100 is a cash market benchmark only. There is no futures or options contract on it, so there is no lot size, no strike chain and no expiry to trade. If you want leveraged or hedged exposure, you do it indirectly through liquid index derivatives like Nifty 50 or through individual stocks that happen to be in the smallcap basket and have their own stock futures, which is rare for true smallcaps.

Named Constituents You Will Recognise

The exact 100 names change at each review, and weights shift daily with price, so always confirm the live list on the NSE Indices factsheet. That said, the index has historically held well known mid to small companies that move in and out as their market cap rises or falls. Recent constituents have included names such as Multi Commodity Exchange of India (MCX), Central Depository Services (CDSL), Karur Vysya Bank, Crompton Greaves Consumer Electricals, Hindustan Copper, NBCC India, Castrol India, Cyient, Birlasoft, Glenmark Pharmaceuticals, Computer Age Management Services (CAMS) and RBL Bank.

Notice the spread of sectors. The Nifty Smallcap 100 is not dominated by banks the way the Nifty 50 is. It leans heavily into capital goods, chemicals, financial market infrastructure, pharma, smaller PSUs and consumer names. This is part of its appeal and its risk. When the domestic capex and manufacturing cycle is strong, the basket can run hard. When liquidity tightens or foreign flows reverse, the same names fall faster than largecaps because their order books are thinner.

Real Index Levels and How to Read Them

Concrete levels help, but only if you treat them as illustrative snapshots. After the 2020 lows the Nifty Smallcap 100 had a powerful multi year run. Through 2023 it traded broadly in the 8,000 to 9,000 region for much of the year, then accelerated. During 2024 it pushed to record territory, printing highs above 18,000 before a sharp correction set in. Through late 2025 and into 2026 it has been choppy, repeatedly testing support after the froth came out of smallcaps.

The reason to keep dates attached to numbers is that smallcap drawdowns are deep. It is common for the Nifty Smallcap 100 to fall 20 to 30 percent or more in a correction while the Nifty 50 falls 8 to 12 percent. A trader who anchors to a peak level and assumes it is a floor will get hurt. Always quote the level with the date and source, for example, the closing level on the NSE Indices daily factsheet.

How to Actually Get Exposure: ETFs and Index Funds

Since you cannot buy the index itself, you buy something that tracks it or a closely related smallcap index. There is no single dominant ETF pinned to the Nifty Smallcap 100 itself, but there are widely used smallcap tracking products. The Nippon India Nifty Smallcap 250 ETF trades on NSE and BSE and is one of the more liquid smallcap ETFs available to retail. On the index fund side, Motilal Oswal Nifty Smallcap 250 Index Fund and similar passive funds from Nippon, SBI and others let you track the broader smallcap basket through a regular mutual fund route with SIPs.

• ETF route: buy units on NSE or BSE during market hours, just like a share, in your existing demat and trading account. You pay the live market price, which can trade at a small premium or discount to NAV.
• Index fund route: invest at end of day NAV through any mutual fund platform, ideal for SIPs and for traders who do not want to manage demat liquidity.
• Active smallcap fund route: a fund manager picks smallcaps rather than tracking the index. Higher expense ratio, and performance can diverge meaningfully from the Nifty Smallcap 100 in either direction.
• Direct stock route: buy individual constituents like CDSL or MCX yourself, accepting single stock risk instead of basket diversification.

A Fully Worked Example in Rupees

Let us walk a realistic single stock trade in a smallcap basket name, with brokerage and statutory charges, because that is where the real profit lives or dies. All numbers below are illustrative and not a prediction. Suppose you buy 500 shares of CDSL, a constituent at the time of writing, at an assumed price of Rs 1,500 as a delivery (CNC) trade. Your buy value is 500 multiplied by 1,500, which is Rs 7,50,000.

Assume you sell three months later at Rs 1,680. Your sell value is 500 multiplied by 1,680, which is Rs 8,40,000. Gross gain before costs is Rs 8,40,000 minus Rs 7,50,000, which is Rs 90,000. Now subtract the real friction. On a discount broker, equity delivery brokerage is typically zero. STT on delivery is 0.1 percent on both buy and sell, so 0.001 multiplied by 7,50,000 is Rs 750 on the buy and 0.001 multiplied by 8,40,000 is Rs 840 on the sell, a total of Rs 1,590. Exchange transaction charges, SEBI fee, stamp duty and 18 percent GST on brokerage and transaction charges add roughly another Rs 200 to Rs 300 on a trade this size. Call total charges about Rs 1,850 to keep it round.

Net gain before tax is therefore about Rs 90,000 minus Rs 1,850, which is roughly Rs 88,150. Because you held three months, this is a short term capital gain on listed equity, taxed at 20 percent for sales on or after 23 July 2024. Tax is 0.20 multiplied by 88,150, which is about Rs 17,630, plus applicable cess. Your in hand profit lands near Rs 70,500. Had you held longer than 12 months, this would instead be a long term gain taxed at 12.5 percent, with the first Rs 1.25 lakh of long term equity gains in the year exempt.

Why There Are No Smallcap Index Options

Traders new to Indian markets often ask how to buy a weekly call on the Nifty Smallcap 100. The honest answer is that you cannot. NSE only lists index derivatives on a small set of high liquidity benchmarks, currently Nifty 50, Nifty Bank, Nifty Financial Services (FinNifty), Nifty Midcap Select and, on BSE, the Sensex and Bankex. SEBI has tightened the framework around index derivatives, including rationalising weekly expiries so that each exchange offers weekly options on essentially one benchmark, while monthly contracts continue on the others.

This matters for risk. Because there is no listed hedge that maps cleanly to the Nifty Smallcap 100, a smallcap portfolio is hard to protect with a single instrument. Some traders hedge imperfectly by shorting Nifty 50 or buying Nifty 50 puts, accepting that smallcaps and largecaps do not move one for one. Remember the contract specifications for the instruments that do trade: Nifty 50 lot size is 65, Bank Nifty is 15, FinNifty is 25 and Sensex is 10. None of these is a substitute for true smallcap exposure, only a rough proxy.

• No Nifty Smallcap 100 futures or options exist, so you cannot get leverage or a direct hedge on the index.
• Imperfect hedges using Nifty 50 derivatives carry basis risk because smallcaps fall harder in stress.
• For pure smallcap downside protection, raising cash or trimming positions is often more reliable than a proxy hedge.

How the Index Is Reviewed and Rebalanced

NSE Indices reviews the Nifty Smallcap 100 semi annually, with data cut offs typically based on the periods ending January and July, and changes implemented from the last trading day of March and September. At each review, companies are re ranked by average free float market capitalisation, and names that have grown into the midcap band or shrunk out of eligibility are replaced. Eligibility also requires the stock to be traded frequently enough and to be available for trading in the derivatives or cash segment per the index rules.

For a trader, rebalancing days create real flows. When a stock is added to the Nifty Smallcap 100, passive index funds and ETFs that track it must buy, which can support the price into the change. When a stock is removed, those same funds sell. These mechanical flows can cause short bursts of volume and price movement around the implementation date that have nothing to do with the company's fundamentals. Knowing the review calendar helps you avoid being surprised by an index driven move.

Risk Profile: Why Smallcaps Behave Differently

Smallcaps carry three risks that largecaps largely do not. First, liquidity risk. Thin order books mean a large order can move the price against you, and in a panic you may not find buyers at all. Second, information risk. Smaller companies attract less analyst coverage, so prices can stay mispriced or be driven by rumour and operator activity. Third, drawdown risk. The basket can lose a quarter or more of its value in a correction, and recovery can take years, not months.

This is also why the Nifty Smallcap 100 can outperform so dramatically in bull phases. The same thin liquidity that punishes you on the way down amplifies gains on the way up when money floods in. The practical lesson is position sizing. A smallcap position should usually be smaller than an equivalent conviction largecap position, because the range of outcomes is wider and the exit door is narrower.

• Liquidity risk: thin volumes mean slippage on entry and exit, worst exactly when you most need to sell.
• Concentration risk: a few sectors like capital goods and chemicals can dominate, so the basket is less diversified than it looks.
• Drawdown risk: 20 to 40 percent peak to trough falls are normal in smallcap cycles, far deeper than the Nifty 50.
• Operator and governance risk: smaller companies are more exposed to promoter pledging, weak disclosures and price manipulation.

Practical Approaches for Indian Traders and Investors

If your aim is long term wealth building, the cleanest route is a SIP into a smallcap index fund or ETF, which spreads your entry across many price points and removes the temptation to time a famously untimeable segment. Because smallcap cycles are long, a multi year horizon and the discipline to keep buying through drawdowns historically matters more than picking the perfect entry. Keep smallcaps as a satellite allocation, not the core of a portfolio.

If you are an active trader, treat smallcaps as a momentum and liquidity game. Trade only the more liquid constituents, use hard stop losses, and respect the fact that gaps can jump straight through your stop because there may be no buyer at your level. Keep a written trading journal of every entry, exit, position size and the reason for the trade, so you can separate skill from a lucky bull market. Tracking your real net returns after STT, charges and tax, as in the worked example above, is the only honest scorecard.
