What can a personal statement say that a fund page cannot?
A fund's return is a property of the fund. An investor's return is a property of the fund and of every date on which that investor bought, sold, paused or waited. The two are rarely the same number, and the difference is usually the larger story.
Built on The CAS X-ray — behaviour gap, cash drag, the Direct-plan leak.
Every lesson before this one has been about a fund: what it costs, what its record decomposes into, whether anything about it forecasts, what its disclosures hide, whose work its numbers are. None of them can say the one thing an investor actually wants to know, which is what happened to their own money.
Only a statement can. A consolidated account statement (CAS — the single statement covering every fund house an investor holds) lists every purchase, every redemption, every switch and every instalment across every fund house, with dates. That turns a set of fund records into a record of decisions — and decisions, unlike funds, can be measured against the alternative of having done nothing.
Five places send one, free: CAMS and KFintech (the two registrars that keep fund houses' investor records), MF Central (both in one place), and NSDL and CDSL (the two depositories, whose monthly statement adds the shares in demat accounts). Only the detailed statement from the first three carries every transaction over the years; the depositories' monthly one carries holdings and that month's transactions. How to get each one, and its password.
Why the interesting numbers are about timing, not choosing
Start from the finding in lesson three. Over ten years, 646 funds and 33,299 observations, nothing measurable here separated the funds that went on to beat their peers from the ones that did not; the strongest ranking in the sample delivered a median of about half a percentage point a year over the median (middle) fund, with a one-in-ten chance of trailing it by more than ten.
If selection is worth roughly nothing on average, then the differences between two households holding similar funds have to come from somewhere else. They come from when and from how much: money that sat in a bank account for eight months before being deployed, an instalment paused in the worst quarter and never restarted, a fund sold during a fall from a previous high and bought back higher, a winner trimmed early and a loser held for years. None of that is visible on a fund page. All of it is on a statement, with dates.
And the one leak that is pure arithmetic
Measured across every equity fund in this build with both plans
1.43% points a yearthe middle fund's Regular-plan mark-up over its own Direct twin, across 519 funds — with the middle half running from 1.09 to 1.68
This is the number from lesson one, applied to the whole shelf rather than one fund. A statement says which folios (the account numbers a fund house gives each holding) are in a Regular plan — the version that pays a distributor commission — and since when, which turns a shelf-wide figure into an arithmetic question about the units actually held.
Computed from the measured divergence of each fund's two NAV series. Anveshan's own study found the same thing across the industry: a median of 1.21% points a year over 33,028 fund-dates.
What the X-ray measures
The one-time reader on the statement page (switched on once Lineage's statement parser is connected) works out, from the statement's own dates and amounts:
- The behaviour gap — the investor's money-weighted return (XIRR: the return given when, and how much, money went in and out) against the same funds' own time-weighted returns (the fund's return regardless of cash flows). The distance between them is what the timing of every contribution and withdrawal cost or earned.
- Cash drag — money that arrived and waited, priced against the market over the exact days it sat.
- Panic exits — redemptions that landed inside a market fall, and what the units would have been worth had they stayed.
- The Direct-plan leak — the figure above, run folio by folio against the actual holding periods rather than as an average.
- Look-through overlap — how much of one fund is already held inside another once each fund is opened up into its stocks, which is the commonest way a portfolio of eight funds turns out to be a portfolio of three.
Every one of those is a counterfactual on a finished period: what did happen, against what would have happened had a date been different. That is a description, which is why it can be computed and shown at all. None of it is a recommendation, and none of it says what to do next.
What happens to the file
The statement is parsed in memory and is not stored — not by Anveshan and not by the API behind it — unless it is saved as a shadow book (below). The findings come back, and nothing persists beyond that response.
The one exception is a choice to keep it: after a read, a statement can be saved as a shadow book — holdings as lines, sales as ghosts priced onward from the sale date — and measured with the postulates in the research register. Saving uses the same sign-in as the rest of Anveshan; it is off unless chosen.

The argument against this lesson
An X-ray of a finished decade is a post-mortem, and post-mortems flatter the reader who reads them. It is easy to look at a paused instalment from 2020 and call it a mistake; it was not obviously a mistake at the time, and the same caution that cost money in one fall protected it in another that never came. The counterfactual — "had the investor simply held" — is the one path out of thousands that can be priced, and pricing it is not the same as proving it was available to anybody in the moment. The behaviour gap is also a description of a period that is over: it tells nobody what to do with the next one, it is not advice, and neither Anveshan nor Lineage Money is an investment adviser or research analyst registered with SEBI (the market regulator).
A description of the past, from what fund houses and the exchanges publish. Not advice, not a recommendation to buy, sell or hold, not a forecast. Neither Anveshan nor Lineage Money is a SEBI-registered investment adviser or research analyst.
