Mid-Cap Fund

A mid-cap fund is an equity scheme that invests at least 65% of its assets in companies ranked 101 to 250 by full market capitalisation.

A mid-cap fund answers a simple question for an Indian investor: how do you own the companies that are no longer scrappy start-ups but not yet household blue chips? Under SEBI's 2017 categorisation rules, mid-caps are the companies ranked 101 to 250 by full market capitalisation. AMFI, together with NSE, BSE and MSEI, publishes this list twice a year (typically January and July) using a six-month average, so the universe shifts as companies grow or shrink.

What you actually own

A SEBI-defined mid-cap fund must keep at least 65% of its corpus in these rank 101-250 names. Think of companies that dominate a niche, are scaling nationally, or are emerging leaders in autos, capital goods, chemicals or financials. They are large enough to be liquid on the exchanges, but small enough that strong execution can re-rate the stock sharply.

The risk-reward trade-off

Mid-caps have historically delivered higher long-term returns than large-caps, but with deeper drawdowns. In a market correction, mid-caps fall faster and recover slower because foreign and institutional money rotates to safety first. After strong rallies, valuations in this segment can run well ahead of earnings, and SEBI has periodically flagged froth here.

A clear point of view

Mid-cap funds suit investors with a horizon of at least seven years and the stomach to sit through 30-40% paper losses without panic-selling. The smartest way to access them for most people is a monthly SIP, which averages out the volatility instead of timing a lumpsum at a peak. Treat a mid-cap fund as a satellite holding that amplifies a core of large-cap or index funds, not as the foundation of your portfolio. Match the allocation to your risk appetite, not to last year's chart-topping returns. For taxation, mid-cap funds follow equity rules: gains held over a year are long-term capital gains, taxed at the prevailing rate above the annual exemption. The honest verdict is that this is a category to enter with patience and a steady SIP, accept the volatility, and let India's emerging leaders compound over a full cycle rather than reacting to every sharp swing.
