Large Cap Fund vs Small Cap Fund

Under SEBI rules, a large cap fund must invest at least 80 percent in the top 100 companies by market value. These are established businesses, often leaders in their industries.

Our page on market capitalisation explains how companies are ranked.

A small cap fund must invest at least 65 percent in companies ranked 251st and beyond. These are smaller, often younger businesses with more room to grow but also more risk.

Our page on large, mid and small cap funds explains the categories.

In strong markets, small caps can rise much faster than large caps, sometimes dramatically. That is what attracts many investors. Large caps usually rise more steadily.

In sharp falls, small caps have historically dropped much more than large caps, and some took years to recover. Large caps also fall, but generally less, and they are easier to sell.

Our page on bull and bear markets explains these cycles.

Large companies are heavily researched, so it is hard for fund managers to find hidden value. Many investors use low-cost large cap index funds for this part. In small caps, active managers have historically had more room to add value through research.

Our page on large cap versus index fund explains this.

Small cap shares trade in smaller volumes. Large small cap funds can struggle to buy and sell without moving prices, and some fund houses have limited fresh lump sum inflows at times.

Our page on fund size and AUM explains why size matters.

Most investors, as a steady equity core for goals five years or more away. First-time investors and those who dislike big swings often start here.

Experienced investors with a solid core, a time frame of ten years or more, and the nerve to sit through deep falls without selling. It should not be a first or only fund.

A common approach is a large cap or index fund as the core and a smaller small cap holding for extra growth potential. Mid cap and flexi cap funds can sit in between.

Our pages on small cap versus flexi cap and large cap versus mid cap explain the middle ground.

There is no fixed rule, and we do not recommend a specific percentage. Size your small cap holding so that a deep fall would not make you sell. Review it yearly, as strong years can make it grow beyond your plan.

Our page on portfolio rebalancing explains how.

SIPs spread purchases across highs and lows, which matters most for volatile small caps. Large lump sums in small caps after a rally carry high timing risk.

Our page on SIP versus lump sum explains why.

Small cap funds often top return charts after a rally. Choosing them for that reason alone is a common and costly mistake. Look at long periods and how funds behaved in falls.

Our page on rolling returns explains how to judge consistency.

Imagine two investors who started SIPs at the same time, one in a large cap fund and one in a small cap fund. In a strong year, the small cap investor is thrilled, far ahead. Then a sharp fall arrives. The small cap fund drops much more, and stays down for a long time. The large cap investor feels uneasy but stays calm.

If the small cap investor holds on for many years, the swings may even out. If they sell in the fall, they lock in the pain. This is an illustration of behaviour, not a forecast.

• When will I need this money?
• Have I lived through a big market fall before, and how did I react?
• Do I already have a steady core?
• How much small cap do my flexi cap or multi cap funds already hold?

Honest answers usually point clearly to the right mix.

Between the two extremes are mid cap funds, which hold companies ranked 101 to 250. They are more volatile than large caps but usually less than small caps. Some investors use mid caps instead of small caps for extra growth with somewhat smaller swings. Our page on mid cap versus small cap compares them.

For the large cap part, many investors use low-cost index funds, since beating the index consistently is hard there. For small caps, an actively managed fund with a good long-term record may add more value. Compare expense ratios either way. Our page on expense ratio explains costs.

Small caps reward patience more than anything else. Investors who can leave the money alone for a decade, without checking it every week, are the ones most likely to benefit. If that does not sound like you, a larger share in large caps is perfectly sensible.

• Large cap: steadier, suits the core.
• Small cap: volatile, suits a small satellite.
• Ten years or more for small cap money.
• Combine and rebalance yearly.
