We have all hear about the importance of diversification in investing. It simply means spreading investments across different sectors and assets to help manage risk and potential returns. And when it comes to diversification in equity MFs, mid-cap funds can be one of the way to approach.
Mid cap mutual funds invest in companies that have moved beyond the early stages of growth but still have room to expand. Unlike large-caps that invest in well-established players (generally with potentially little room to growth) and small-caps that have high volatility, mid-caps focus on potentially balancing growth and returns, while spreading risk. In this article, we explore how you can build a robust portfolio with a mix of mid-cap funds that add diversification benefits.

What are Mid-Cap Mutual Funds?
A mid cap mutual fund is an equity mutual fund scheme that invests in mid-sized companies that are ranked between 101st to 250th in terms of market capitalisation. According to SEBI’s regulations, mid-cap mutual funds have to invest at least 65% of their assets into mid-cap stocks.
Mid-cap companies are typically established businesses that are still expanding their operations and market presence. As a result, mid cap mutual funds may offer higher growth potential than large-cap funds, but they can also be more sensitive to market cycles. Their behaviour often reflects a balance between growth and, which can support portfolio diversification.
Types of mid-cap funds investors can consider:
Actively managed mid-cap funds, where fund managers select stocks based on research and market conditions
Passively managed mid-cap index funds, which aim to replicate the performance of a mid-cap benchmark like the Nifty Midcap 150 index
Large and mid-cap funds, which spread investments across both market capitalisations for balanced equity exposure
Role of Mid-Cap Funds in Portfolio Diversification
Mid cap funds add a unique layer of diversification because they behave differently from large-cap and small-cap categories. While investing in small cap funds may offer potential higher return (given how these companies are still in nascent stages and have growth potential), this growth possibility if linked to higher volatility. Mid-caps, on the other hand, help investors manage the volatility with investment in more established companies compared to small-caps.
Here's how they contribute to creating a diversified portfolio:
Sector diversification:
Mid-cap mutual funds invest across sectors such as power, construction, financial services, IT and pharma, helping spread exposure and reduce dependence on any single industry.
Company size balance:
Mid-cap investment funds sit between large-caps and small-caps. While large-cap funds offer relative stability compared to small-caps and mid-caps, small-caps offer more growth potential against high volatility. Mid-caps help balance the two, supporting diversification within the equity portion of a portfolio.
Risk mitigation:
By investing in multiple companies across sectors, mid-cap funds help reduce the impact of any single stock or sector underperforming.
Access to growing businesses:
A mid-cap fund provides exposure to companies in their expansion phase, which may offer higher growth potential than established large-cap firms but with higher volatility.
