Portfolio Hygiene

You Have 15 Mutual Funds. That Is Not Diversification.

Holding too many mutual funds does not make you safer. It usually means you are paying more for returns that just copy the index. Here is why five or six good funds beat fifteen.

When someone sends me their portfolio for a review, I often find the same thing — fifteen, eighteen, sometimes twenty different mutual funds. They think this makes them safe. It does the opposite. Let me explain why, without any jargon.

How people end up with so many funds

It is rarely a plan. It happens slowly. A friend recommends a fund, so you start a SIP. Next year a magazine names the "top fund", so you add that. Your bank pushes one, so you take it. A few years later you look up and you are holding eighteen funds and you cannot remember why you bought half of them.

Why too many funds is a real problem

Here is the thing most people do not realise. If you hold fifteen equity funds, they are mostly buying the same top companies — your Relianes, your HDFCs, your Infosys. So underneath, your funds overlap heavily. You think you own fifteen different things, but really you own the same basket fifteen times over.

And what happens when your portfolio looks like the whole market? Your returns also start to look like the whole market — except you are paying a fund management fee on each one. So you get index-like returns while paying much more than an index fund would cost. The great investor Peter Lynch had a word for this. He called it "diworsification" — diversifying yourself into worse results.

Signs your portfolio is over-diversified

Check if any of these sound like you:

So how many funds do you actually need?

For most people, four to six funds are plenty. A simple, clean portfolio might look like this — one large-cap or index fund as the base, one flexi-cap fund, one mid-cap fund if you can handle more ups and downs, one short-duration debt fund for stability, and maybe one international fund. That is it. Each one has a clear job. Nothing overlaps without reason.

A smaller, well-chosen set of funds is easier to track, cheaper to hold, and far easier for your family to understand if they ever need to. Simplicity is not a compromise here — it is the better strategy.

What to do if you already have too many

Do not just sell everything in a hurry — there can be exit loads and tax to consider. The right way is a proper review. Look at where the overlap is, decide which funds to keep, and consolidate gradually in a way that does not trigger unnecessary costs. This is exactly the kind of clean-up I do in a portfolio hygiene check.

If your portfolio has quietly grown into a jungle of funds, send it to me for a review. We will figure out what is actually working and tidy up the rest.

Common Questions

How many mutual funds should I have?

For most investors, four to six funds are enough — for example one large-cap or index fund, one flexi-cap, one mid-cap, one short-duration debt fund, and maybe one international fund. Each should have a clear, distinct job.

Is it bad to have many mutual funds?

Yes, usually. Holding fifteen or more equity funds means they overlap heavily and your returns start to copy the index, while you pay more in fees. This is sometimes called diworsification.

How do I know if my funds overlap?

If you hold several funds in the same category, your returns closely track the Nifty 50, and you cannot explain why you own each fund, you likely have heavy overlap. A portfolio review can show the exact overlap.

Should I sell my extra funds immediately?

Not in a rush. There can be exit loads and tax on gains. The better approach is a planned consolidation that decides what to keep and reduces the rest gradually to avoid unnecessary cost.
