How Many Mutual Funds Should You Own?
Three to five. More funds usually means more overlap, not more diversification — you end up owning the index with extra fees.
Somewhere between fund number four and fund number fifteen, a portfolio stops being a strategy and becomes a drawer of impulse purchases — each fund bought because some list, ad or friend recommended it that year. The question “how many funds?” is really “at what point does another fund add nothing?” — and the answer arrives shockingly early.
The reason is overlap.

ExampleNikhil proudly holds 14 funds: six large-caps, four flexi-caps, three ELSS, one mid-capMedium-sized companies between large- and small-caps.. An overlap check shows his top-10 holdings are nearly identical across eleven of them — he owns a closet index fundA fund that simply tracks a market index at very low cost. at ~1.8% average fees, with 14 statements to ignore. Consolidated to four (indexA basket of stocks tracked together to represent a market. core, mid-capMedium-sized companies between large- and small-caps., international, short-duration debt), his fees drop by more than half, his crash behaviour is unchanged, and for the first time he can say what he owns and why.
Common mistake“I add the best fund from every year’s top-performers list.” Last year’s topper is usually just the category that had a hot year — buying it is buying the rear-view mirror, and it’s how portfolios bloat to 12 look-alike funds. Pick categories deliberately once; change funds only for sustained decay or mandate drift, not because a list changed.
Test yourselfYou hold six large-cap funds for ’diversification’. What’s the problem?
They all fish from the same ~100 large companies — you own the index with active fees and six statements. Real diversification is across CATEGORIES (broad core, mid/small, international, debt): 3-5 funds cover everything a fund portfolio can offer.

FAQs
Is it bad to have all my funds with one AMC?
Your money is held by custodians and regulated by SEBI, so an AMC failing doesn’t take your units with it — single-AMC risk is operational, not existential. The better reason to spread across 2-3 AMCs is style risk: one fund house’s philosophy (and its bad years) will infect all its schemes similarly. Diversify managers the way you diversify stocks — a little, deliberately, without collecting.
