Understanding Mid Cap Index Funds: Definition, Advantages, and Types

If you're a beginner investor looking to earn predictable returns, you're probably considering investing in index funds. The idea being investing in them means investing stocks in the portfolio in similar proportions to market indexes.

So, funds will perform similarly to the index or won't go into losses, bringing you returns even in the worst market conditions. But if you've done your research, you know investing in index funds is more complex than that. Choosing a market index from a particular market cap is equally important.

If you want to gain high returns from your investments and are willing to earn returns in the long term, consider investing in midcap index funds. Don't know what they are? Read this blog to find out.

What are midcap index funds?

A midcap index fund is a mutual fund that invests in stocks and securities in a similar proportion to the market's midcap index. Now what is a midcap index?

It is a stock market index that measures market fluctuations for stocks of midcap companies or companies ranked between 101 and 250, having market capitalizations ranging between Rs. 5,000 and Rs. 20,000 cr. Moreover, it is typically constructed by selecting companies from the National stock exchange (NSE) or the Bombay stock exchange (BSE).

Since an index fund invests in stocks proportional to the investment pattern of the index, the returns one earns on midcap index funds depend on the performance of the midcap index.

Why Should You Invest in a Mid-Cap Mutual Fund?

#1. Higher returns

Between smallcap, midcap, and large-cap mutual funds, midcap funds offer the best balance between returns and lower investment risk. Here's why.

Unlike large-cap funds that contain stocks of large-cap companies that grow slowly, mid-cap funds contain stocks of companies that show a high growth potential. This means they are more likely to offer better returns in the long term.

Also, midcap funds are less volatile than small-cap funds, given they are more diversified. This means although they might not offer the same returns as smallcap funds, they offer more predictable returns.

#2.  Low-cost investments

Mutual fund investing comes with various associated charges, including fund management fees which can amount to 1% of the total asset base, maintenance costs, entry load, exit load, brokerage fees, and more. But did you know that these charges are significantly reduced in midcap index funds?

Well, midcap index funds don't have fund managers actively buying or selling stocks, creating strategies or researching the right stocks for investing. Instead, they are passively managed, given they closely track the midcap market index. Naturally, investors pay less towards managing the fund, lowering the investment cost significantly.

#3. Diversification

If you didn't know already, midcap indexes have stocks of companies across various sectors, including consumer durables, information technology, realty, metals and mining, construction, power, and more. This means investors automatically diversify their portfolios when they invest in midcap index funds.

In other words, a market fluctuation will not affect stocks in all these sectors equally, effectively lowering the overall investment risk.

#4. Low human error

Mutual funds that rely on the fund manager's expertise to get good returns can occasionally experience losses due to human error. But since midcap index funds are passively managed, no human bias or mistakes are involved.

That said, they may still be susceptible to tracking errors or show a deviation of the difference in earned returns between the target index and the chosen index fund.

Different types of midcap index in India

Investing in mid-cap index funds offers several advantages.

1. High growth potential- Midcap companies are in their expansion stage, offering better growth opportunities compared to large-cap firms, especially in a growing economy.

2. Sector diversification- Midcap index funds invest across multiple industries, reducing the risk of overdependence on a single sector's performance.

3. Cost efficiency- These funds have lower expense ratios than actively managed funds, making them a more affordable option for investors.

4. No fund manager bias- Since these track a predefined index, they avoid the risk of poor stock selection or management errors.

5. Long-term wealth creation- Consistent investments in midcap index funds can yield significant wealth over time for long-term investors.

6. Access to emerging companies- These funds provide exposure to promising companies that are transitioning to become market leaders.

7. Market capitalisation balance- They offer a balance between the stability of large-cap funds and the aggressive growth of small-cap funds.

FAQs

Is it good to invest in a mid-cap index fund?

Yes, investing in a mid-cap index fund can be a smart choice if it aligns with your risk tolerance, time horizon, and financial goals. These funds suit investors who can handle moderate risk and are focused on long-term growth. While they offer the potential for higher returns, they also experience greater market volatility. If you prefer a more stable option, a large-cap index fund may be a better fit.

Which is the oldest mid-cap index fund in India?

The oldest active mid-cap index fund in India is the Franklin India Prima Fund. Launched on December 1, 1993, this fund is often regarded as a pioneer of mid-cap investing in the country. As of September 2025, the fund’s Assets Under Management (AUM) stood at Rs. 12,251 crores. Franklin India Prima Fund is managed by R Janakiraman Rengaraju and Akhil Kalluri.

What is the investment time horizon for a mid-cap mutual fund?

Mid-cap mutual funds are best suited for investors with a long-term investment horizon of at least five to ten years. These funds can be volatile in the short term since mid-sized companies are more sensitive to market fluctuations. However, with patience and time, they often deliver robust returns.

Are mid-cap funds risky?

Yes. Mid-cap funds are considered moderately risky because they invest in mid-sized companies that are still in their growth phase and more exposed to market fluctuations. They tend to be more volatile than large-cap funds but generally less risky than small-cap funds. Despite the risks, they offer strong growth potential for investors with a balanced risk appetite.

Is SIP or lump sum better for mid-cap fund investments?

Both Systematic Investment Plan (SIP) and lump sum investing have their own advantages. An SIP in a mid-cap mutual fund lets you invest a fixed amount at regular intervals, helping you benefit from rupee-cost averaging. It’s ideal for disciplined investors who prefer consistent investing. In contrast, a lump sum investment allows you to invest a large amount at once and potentially benefit from favorable market conditions.
