Large Cap vs Mid Cap vs Small Cap Funds

SEBI defines the segments by rank on full market capitalisation, so the labels mean the same thing across every AMC.

The definitions

• Large cap: companies ranked 1–100. Funds must hold at least 80% here.
• Mid cap: ranked 101–250. Funds must hold at least 65% here.
• Small cap: ranked 251 and below. Funds must hold at least 65% here.

The trade-off

Moving down the size scale raises both expected return and volatility. Large caps are established and widely researched, so they fall less and recover sooner. Small caps can compound dramatically but are illiquid and unforgiving in a downturn — the same fund can top the 5-year table and halve within a year.

Combining them

Rather than assembling the three yourself, consider a flexi cap (manager decides the allocation) or a multi cap (mandated minimum 25% in each). Both give diversified exposure without you having to time the rotation between segments.
