Nifty Midcap 150 Index: Meaning, Stocks & How It Works

Mid cap companies occupy the space between relatively established large cap companies and smaller, emerging businesses. The Nifty Midcap 150 Index is a broad-based equity index that tracks the performance of 150 mid cap companies listed on the National Stock Exchange (NSE).

The index comprises companies ranked from 101 to 250 based on full market capitalisation within the broader Nifty 500 universe. In simple terms, these companies come after the top 100 large cap companies but before smaller companies in the market.

With companies from multiple sectors, the index gives investors, fund managers and analysts a diversified view of how India’s mid cap segment is performing. This article explores how the index is calculated, its sector and stock composition, its potential benefits and risks, and the different ways to invest in it.

How is NIFTY Midcap 150 calculated?

The Nifty Midcap 150 is calculated using the free-float market capitalisation method, meaning that the index looks at the market value of shares that are available for public trading. Shares held by promoters, the government or other strategic investors are not included in this calculation.

The higher a company’s free-float market capitalisation, the higher its weight in the index. So, a company with a larger publicly traded market value can have a greater impact on the movement of the Nifty Midcap 150. For example, if a company has 1 lakh publicly available shares priced at ₹30 per share, its free-float market capitalisation would be ₹30 lakh. (For illustrative purpose only).

Free-float market capitalisation = Shares outstanding x Share price x Investible Weight Factor (IWF)

The Nifty Midcap 150 formula is as follows:

Index value = (Current free-float market capitalisation / Base free-float market capitalisation) x Base index value

The Nifty Midcap 150 has a base date of April 1, 2005, and a base value of 1,000. It was launched on April 1, 2016, and is calculated in real time during market hours. The index is also reviewed twice a year, during which companies may be added or removed based on predefined eligibility criteria. This helps ensure that the index remains representative of the mid cap segment of the market.

Factors influencing the Nifty Midcap 150

Mid cap stocks tend to be volatile and sensitive to changes in the markets and economy. Here are some factors that may influence index movements:

Economic cycles

Mid cap companies are often sensitive to economic cycles. During periods of economic expansion, some mid cap businesses may experience growth due to operational flexibility. During economic slowdowns, they may face greater pressure because of relatively limited financial buffers and narrower revenue streams.

Interest rate environment

Rising interest rates increase borrowing costs and may affect corporate profitability. Changes in interest rates may also influence investor allocation between equities and fixed-income instruments, impacting mid cap valuations.

Liquidity conditions

Periods of higher market liquidity may support increased participation in mid cap stocks. Conversely, tightening liquidity conditions may result in increased volatility and selling pressure.

Currency movements

A depreciating rupee may raise input costs for mid cap companies that rely on imported raw materials, which can affect margins and earnings visibility.

Regulatory changes

Changes in regulations and compliance requirements may have a proportionately higher impact on mid cap companies due to relatively limited resources compared to large cap firms.

Global risk sentiment

Elevated global uncertainty may lead investors to adopt a more cautious stance, which can affect demand for mid cap stocks.

Domestic consumption trends

Trends in domestic consumption may influence revenue growth for mid cap companies that cater to local markets.

Corporate earnings growth

Quarterly earnings announcements can influence short-term price movements of mid cap stocks, reflecting changes in business performance and market expectations.

Benefits of Nifty Midcap 150 index

The Nifty Midcap 150 index offers the following potential benefits to investors:

Broad diversification within mid caps

The index provides exposure to 150 mid-sized companies across multiple sectors. While diversification may help reduce the impact of individual stock performance, it does not eliminate overall equity market risk.

Cost considerations

The index is tracked by passive investment products, which typically have lower expense ratios compared to actively managed funds.

Simplified access to the mid cap segment

Index-based exposure reduces the need for individual stock selection and ongoing monitoring, offering a structured way to access the mid cap universe.

Potential for long-term growth over time

Mid cap companies may offer potential for higher long-term growth than large cap companies, accompanied by relatively higher volatility. Such exposure may be suitable for investors with a long investment horizon and a very high tolerance for risk.

Risks of Nifty Midcap 150 index

Mid cap companies may grow faster than large cap companies over the long term, but they can also be more sensitive to market movements, business cycles and investor sentiment. Here are some key risks:

Higher volatility: Mid cap stocks can witness sharper price movements than large cap stocks. During market corrections, the Nifty Midcap 150 may fall more sharply than broader or large cap indices.
Market risk: The index is equity-oriented and is affected by factors such as economic growth, interest rates, inflation, corporate earnings and global market trends. These factors can influence the performance of the index.
Liquidity risk: Some mid cap stocks may have lower trading volumes compared to large cap stocks. This can make them more sensitive to buying and selling pressure in the market.
Business risk: Mid cap companies may still be in the expansion phase. They may face challenges related to competition, funding, profitability, governance or execution, which can affect their stock performance.
Sector concentration risk: Although the index includes companies across several sectors, some sectors may have a higher weight than others. Any adverse development in a high-weight sector can influence index performance.

To sum up, the Nifty Midcap 150 may not be suitable for investors with a low risk appetite or a short investment horizon. Investors need to have a long horizon and the ability to tolerate short-term volatility.

Who should invest in Nifty Midcap 150?

Investors may consider exposure to the Nifty Midcap 150 if they:

Have a long investment horizon: Mid cap stocks can move through phases of sharp rises and corrections. Investors with a long-term view may be better placed to stay invested through such market cycles.
Have a very high risk appetite: The Nifty Midcap 150 is equity-oriented and can be affected by market volatility, economic conditions and company-specific developments. It may suit investors who can tolerate short-term fluctuations.
Want diversified mid cap exposure: The index includes 150 mid cap companies across sectors. This can provide broader exposure than investing in a few individual mid cap stocks.
Prefer a rule-based approach: Investors who do not want to select individual mid cap stocks may consider index-based exposure through passive investment products that track the Nifty Midcap 150.
Want to broaden their portfolio: The Nifty Midcap 150 can be considered by investors who already have large cap exposure and want to add mid cap allocation for potential long-term growth.

Before investing, investors should assess their financial goals, investment horizon and risk appetite. They may also consider consulting a financial advisor to decide whether mid cap exposure is suitable for their portfolio.

How to invest in Nifty Midcap 150?

Investors cannot invest directly in an index. Exposure can be obtained through index funds or ETFs tracking this index, aiming to replicate its performance (subject to tracking error). Such schemes typically invest in the same stocks and in similar proportions as the index. Returns depend on index performance and prevailing market conditions.

Investments may be made through:

• The official website of the Asset Management Company
• AMFI-registered mutual fund distributors empanelled with the AMC
• Online investment platforms
• Offline through a distributor or by submitting a filled-out form to the AMC’s official point of acceptance.
• Demat account (ETF investments can only be made through this route.)

Alternatively, investors who seek mid cap exposure but prefer an active approach may consider mid cap mutual funds. While these funds may use the Nifty Midcap 150 as their benchmark, they do not replicate it. Instead, the fund manager selects and manages a portfolio of stocks with the aim of outperforming the benchmark over the long term. However, performance depends on the fund manager’s investment decisions as well as market conditions, and outperformance is not assured.

Are mid cap funds better than large cap funds?

Mid cap funds are not inherently better than large cap funds. They invest in different segments of the equity market and may be suitable for different investment objectives, risk appetites and investment horizons. The choice between the two depends on n investor’s financial goals rather than one category being superior to the other.

Here’s a detailed break down of large cap funds vs mid cap funds:

Basis of comparison	Mid cap funds	Large cap funds
Investment universe	Primarily in medium-sized companies, many of which are still expanding.	Primarily in larger, well-established companies with mature business models.
Growth potential	May offer higher long-term growth potential as the underlying companies expand. However, this comes with higher market risk.	May offer relatively more stable growth, although their larger size can sometimes limit the pace of expansion.
Volatility	Generally experience greater price fluctuations, particularly during uncertain market conditions.	Tend to be relatively less volatile because of the scale and position of underlying companies.
Suitable for	Investors who can accept higher risk and withstand short-term market movements.	Investors seeking equity exposure with lower risk than that of mid caps.
Investment horizon	Typically better suited to a longer investment horizon, giving investors more time to ride out market volatility.	Can also be held for the long term but may offer relatively greater stability along the way.
Liquidity	Stocks may have relatively lower trading volumes, which can increase price movements during periods of market stress.	Stocks generally have greater liquidity because they are more widely traded.
Market behaviour	May perform strongly during periods of economic expansion but can experience sharper declines during market downturns.	May show greater resilience during uncertain periods, though performance depends on the market cycle.
Portfolio role	Can add long-term growth potential to a portfolio for investors comfortable with higher risk.	Can provide a relatively stable foundation for the equity portion of a portfolio.
