Multi Cap vs Flexi Cap Funds: Understanding the Real Difference

Introduction

Multi Cap and Flexi Cap funds are two of the most popular equity mutual fund categories in India, and investors often confuse one for the other. Before comparing them, it helps to understand a few basic terms that SEBI uses to classify stocks by size.

Large Cap, Mid Cap and Small Cap: The SEBI Classification

As per SEBI’s Master Circular for Mutual Funds, every listed company is ranked by its full market capitalization and grouped into one of three categories:

• Large Cap Companies — Ranked 1st to 100th in terms of full market capitalization.
• Mid Cap Companies — Ranked 101st to 250th in terms of full market capitalization.
• Small Cap Companies — Ranked 251st and onwards in terms of full market capitalization.

AMFI publishes this list of companies twice a year, based on average market capitalization data as of the end of June and December, so that all mutual funds follow the same classification.

What Is Full Market Capitalization?

Full market capitalization is calculated as:

Full Market Capitalization = Total Number of Shares Issued × Current Market Price per Share

This figure includes all outstanding shares of a company — promoter holdings, government stakes, and locked-in shares — not just the shares that are freely available for public trading (free float).

Multi Cap Fund

A Multi Cap Fund is an equity scheme that must invest at least 75% of its total assets in equity and equity-related instruments, allocated across market capitalizations as follows:

• Minimum 25% of total assets in large cap stocks
• Minimum 25% of total assets in mid cap stocks
• Minimum 25% of total assets in small cap stocks

This is often referred to as the “25-25-25 rule.” It ensures that a Multi Cap Fund maintains proper diversification across large-, mid-, and small-cap companies, rather than being overly concentrated in any one segment.

Example: Multi Cap Fund Allocation

If the total assets of a Multi Cap Fund are ₹1,00,000, the minimum mandatory allocation would look like this:

• Large cap companies: ₹1,00,000 × 25% = ₹25,000
• Mid cap companies: ₹1,00,000 × 25% = ₹25,000
• Small cap companies: ₹1,00,000 × 25% = ₹25,000

The remaining 25% of assets can be invested at the fund manager’s discretion in debt, money market instruments, or other permitted instruments.

Flexi Cap Fund

A Flexi Cap Fund is an equity scheme that must invest at least 65% of its total assets in equity and equity-related instruments. Unlike a Multi Cap Fund, there is no mandatory minimum allocation to large cap, mid cap, or small cap stocks — the fund manager has complete discretion to move between market capitalizations based on market conditions and opportunities.

Flexi Cap Funds fall under the equity category of mutual fund schemes. Any amount not allocated to equity can be invested in money market instruments and other instruments permitted under SEBI guidelines.

Example: Flexi Cap Fund Allocation

If the total assets of a Flexi Cap Fund are ₹1,00,000, at least 65%, i.e., ₹65,000, must be invested in equity and equity-related instruments, in any proportion the fund manager chooses across large, mid, and small cap stocks.

Conclusion

Both Multi Cap and Flexi Cap Funds are diversified equity schemes, but they differ in how strictly they must be allocated across market capitalizations. A Multi Cap Fund follows a fixed 25-25-25 structure across large, mid, and small caps, offering built-in diversification. A Flexi Cap Fund, on the other hand, only requires a minimum 65% equity exposure and leaves the allocation entirely to the fund manager’s judgment. This structural difference is what ultimately drives the difference in risk and return profile between the two categories.
