How to See What Your Portfolio Actually Holds

The gap between the statement and the portfolio

Kabir can list his holdings. What he cannot do, without work, is say which companies he owns and in what proportions — and that is the thing that determines what happens to his money.

The gap between those two views is wider than most people expect, for a specific reason. Funds drawn from the same universe hold overlapping companies, and funds weighted by company size hold the largest ones in the largest amounts. So the biggest companies appear in fund after fund, and their share of the combined portfolio is larger than their share of any single fund.

Owning six funds can mean owning the same twenty companies six times, in slightly different proportions. Nothing about the statement reveals this.

Doing it

The procedure is dull and it is the only way to know.

Collect the holdings. Every fund publishes its portfolio periodically, with each company's weight. Get the most recent one for each fund you hold.

Weight by what you have in each fund. A company at some weight inside a fund that is a quarter of your money contributes a quarter of that weight to your portfolio. Multiply each company's weight in the fund by the fund's share of your total.

Add up across funds. Sum each company's contributions from every fund. That total is what you actually own in that company.

Sort the result. Largest first. This is your portfolio, and it is the first time you have seen it.

Two details. Use the same reporting date for every fund where you can, since portfolios change. And include everything — shares held directly, employer holdings, anything in a retirement account. The point is the combined position, and a holding left out of the count is precisely the one that causes trouble.

What to look at once you have it

How much sits in the top few. There is no threshold we can give you, and you do not need one: the question to ask is whether a serious problem at any single name on that list would change your plans. If yes, you have found something worth acting on regardless of what any rule of thumb says.

How much sits in one industry. Group the list and add it up. Industry concentration is easier to accumulate accidentally than company concentration, because a fund can be well spread across companies that all depend on the same conditions.

How much any two funds share. If two funds' holdings largely coincide, the second is buying you a charge rather than diversification — combining broad market indices.

And whether your own income is on the list. If you work in an industry that appears near the top, your true exposure is larger than the portfolio shows, because your future earnings are the largest asset you own and they are not in the spreadsheet.

Why it gets worse on its own

The important property: concentration accumulates without anybody deciding anything.

Whatever rises fastest becomes a larger share of what you own, by arithmetic alone. So a portfolio left alone drifts towards whatever has recently done well — which is also what has become most expensive relative to what it earns. Success concentrates you, quietly, in the direction of the thing that has already run.

Two consequences. The measurement has to be repeated, because a result from three years ago describes a portfolio you no longer have. And the only mechanism that reverses the drift is rebalancing — how rebalancing controls risk.

It also explains why a strong year is the moment to run this check rather than the moment to relax, which is the argument in why good returns do not make a portfolio safe.

What to do with a concentrated result

Reducing a large position is not always simple: selling may realise a substantial tax bill, and an employer holding may carry restrictions.

Three approaches that avoid an all-at-once decision. Stop adding — direct new contributions elsewhere, which costs nothing and stops the position growing further. Reduce gradually, spreading sales across tax years. And build around it, adding holdings that do not depend on the same conditions, which is slower but requires no sale at all.

Which applies depends on how large the position is and how much of the risk you can tolerate while you unwind it. Maya's case — a large holding arriving rather than being chosen — is the hardest version, because the position is already there before any decision is made.

The honest gap

We give no target for what counts as too concentrated, and no figures for how concentrated Indian funds or indices actually are.

Both would need constituent and weight data, which this repository does not hold. The information exists — every fund publishes its portfolio — and it is specific to what you own, so a general figure would be the wrong shape of answer even if we had it. The method above is what transfers; the numbers are yours.

What to take away

Your portfolio is the combined list of companies underneath your funds, not the list of funds. The combined list is more concentrated than it looks, it becomes more so every year without anyone deciding, and it takes an afternoon to compute.

Do it once and you will know whether you own what you think you own. Do it after a strong year and you will find out where success has quietly taken you.
