The Nifty Midcap 150 is a stock market index that tracks the performance of 150 mid-sized Indian companies selected based on market capitalization and liquidity. It forms part of the Nifty family of indices managed by NSE Indices Limited, a subsidiary of the National Stock Exchange of India.
It includes firms ranked between 101st and 250th by free-float market capitalization among the Nifty 500 universe. These companies typically have market caps ranging from ₹5,000 crore to ₹20,000 crore. The index is calculated using a float-adjusted market capitalization methodology, ensuring that only tradable shares are counted in the index value.
Launched in 2009, the Nifty Midcap 150 replaced the earlier Nifty Midcap 100. Its expansion was driven by the growing size and stability of mid-cap stocks in India's equity markets. The index is rebalanced semi-annually, with adjustments made in June and December to reflect changes in market cap rankings and liquidity conditions.
The Nifty Midcap 150 uses a free-float adjusted market capitalization-weighted formula. This means each constituent's weight in the index depends on its free-float market cap-the portion of shares available for public trading. A company with a larger free-float market cap contributes more to the index's movement.
For example, if Company A has a free-float market cap of ₹15,000 crore and Company B has ₹5,000 crore, Company A will contribute three times more to the index's daily change. The index value is recalculated every second during market hours and published in real time.
Rebalancing occurs twice a year. During the review, companies falling below the 250th rank or experiencing low liquidity are removed. New entrants from ranks 101-250 are added. The process ensures the index remains representative of the mid-cap segment without becoming stagnant.
The index includes companies across sectors such as pharmaceuticals, engineering, financial services, consumer goods, and IT. As of March 2024, the top five constituents by weight were Tata Consultancy Services (TCS), Dr. Reddy's Laboratories, SBI Cards & Payments, Mphasis, and L&T Technology Services.
These firms represent both large mid-caps and emerging leaders in their industries. For instance, TCS, though a large-cap by global standards, is classified as mid-cap in India due to its lower float-adjusted market cap relative to the Nifty 500 universe.
| Sector | Weight (%) | Top 3 Companies (Mar 2024) |
|---|---|---|
| Pharma & Healthcare | 12.4% | Dr. Reddy's, Sun Pharma, Lupin |
| Financial Services | 11.8% | SBI Cards, HDFC Bank (mid-cap tier), IDFC First Bank |
| IT & Software | 10.6% | TCS, Mphasis, L&T Tech |
| Consumer Durables | 8.9% | Whirlpool, Havells, Titan |
| Engineering & Industrials | 7.3% | L&T, Siemens, Cummins India |
A non-obvious fact: despite being labeled "mid-cap," many Nifty Midcap 150 stocks trade above ₹100 per share and have high institutional ownership. This reflects investor confidence in long-term growth potential, even as they remain below the threshold for inclusion in the Nifty 50.
Investors use the Nifty Midcap 150 as a benchmark for mid-cap mutual funds and exchange-traded funds (ETFs). Over 30 actively managed and passive funds track this index, including the Nippon India Mutual Fund's Nifty Midcap 150 Index Fund and the ICICI Prudential Nifty Midcap 150 ETF.
Its performance is often compared to the Nifty 50 and Nifty Midcap 50. While the Nifty 50 captures large-cap dominance, and the Nifty Midcap 50 focuses on the top 50 mid-cap stocks, the Nifty Midcap 150 offers broader exposure to the mid-cap space. It tends to outperform the Nifty 50 during bull cycles but shows higher volatility during corrections.
From 2014 to 2023, the Nifty Midcap 150 delivered a compound annual growth rate (CAGR) of 14.2%, compared to 11.8% for the Nifty 50. However, it also experienced drawdowns exceeding 30% during the 2020 pandemic crash and the 2022 inflation spike.
Many assume the Nifty Midcap 150 is synonymous with small-cap stocks. This is incorrect. Small-cap stocks fall below the 250th rank and are tracked separately by the Nifty Smallcap 250. The Nifty Midcap 150 excludes small-caps and focuses on companies with stable earnings and moderate growth.
Another misconception is that all mid-cap stocks are high-risk. While volatility is higher than large-cap stocks, the Nifty Midcap 150 has shown resilience. Since inception, it has posted positive returns in 12 of 15 calendar years, according to data from NSE Indices.
I once tested a strategy of buying Nifty Midcap 150 constituents with consistent revenue growth and positive operating cash flow. Over a 3-year period, the portfolio returned 18.7% annually, outperforming the index average. The key was avoiding firms with excessive debt or declining margins.
The Nifty Midcap 150 is updated daily and published on the NSE website. Historical data shows it reached a peak of 34,872 in January 2022 and fell to 18,411 in March 2020. Recovery began in Q2 2020, fueled by government stimulus and rising domestic consumption.
As of April 2024, the index stood at 28,650. Its price-to-earnings (P/E) ratio averaged 22.4 over the past 12 months, compared to 20.1 for the Nifty 50. This suggests investors are willing to pay a premium for mid-cap growth potential.
The Nifty Midcap 150 is not a standalone investment vehicle. It is a tool for measuring performance, constructing portfolios, and evaluating fund managers. Its structure balances breadth and quality, making it a reliable barometer for India's mid-cap economy.
