Motilal Oswal BSE 1000 Index Fund

Benchmark, benchmark return and AUM figures on this page are AMFI's own published disclosure — the same SEBI-mandated benchmark every fund must declare and report against, sourced from AMFI's Fund Performance data. StockProof does not compute the benchmark return itself: it shows the number AMFI and the fund house publish, exactly as published. StockProof does not rank funds or benchmarks by this figure, and this is not a recommendation to buy, sell or hold anything.

This section is matched to the scheme above by FUND NAME, not by scheme code or ISIN — AMFI's benchmark-disclosure API carries neither, unlike its NAV files. Measured 2026-08-29 across the whole universe, this name match succeeds for about 86% of funds; most misses are small spelling or punctuation drift between AMFI's own two systems, not a wrong match — a fund with no match here simply shows no data rather than another fund's. One disclosed row also covers BOTH the Regular and Direct plan of a fund together, because that is the granularity AMFI itself publishes at — one level coarser than the per-plan scheme codes StockProof otherwise tracks.

These holdings are the fund house's own SEBI-mandated monthly portfolio disclosure, read from the file the AMC publishes and shown as published. StockProof does not estimate, model or infer a single holding. The portfolio is a SNAPSHOT on the date shown — usually a month-end — and a fund can and does trade in between, so what it holds today is not necessarily what is listed here. Nothing on this page ranks funds, scores them, or recommends buying, selling or holding anything.

StockProof can only link a holding to a company page if that company is in the Nifty 500 universe it tracks. Everything the fund disclosed is listed here either way — holdings outside that universe are shown with their real names and weights and counted explicitly as "outside tracked universe", never dropped. Two coverage figures are given because they can differ enormously and either one alone is misleading: the share of holding LINES that link, and the share of disclosed WEIGHT that links. Parag Parikh Flexi Cap Fund is the standing example — under half its lines link, but around three-quarters of its weight does, because its unlinked positions are a handful of very large US holdings.

Coverage varies enormously by fund type and low coverage is a fact about the universe boundary, not a defect. Large-cap, flexi-cap and index funds typically X-ray at over 90% of disclosed weight; small-cap funds fall to roughly 44–75%, because much of what they own sits below the Nifty 500; and a pure debt fund links at zero, because bonds are not companies in StockProof's universe at all. Read the coverage figure before reading the holdings: at 45% coverage the listed companies are a minority of the fund.

The disclosed holdings usually do not add to 100% of the fund. The remainder is cash, TREPS, repo and derivative margin, which the AMC reports without a security line. Weights here are the AMC's own "% to NAV" figures, so they are shares of the WHOLE fund and can be added up directly — but the total falling short of 100% is normal and is shown rather than scaled away.

Holdings are matched to companies by ISIN — the security's own permanent identifier, never by name — so a matched company is the security the fund disclosed and not a guess. The FUND itself is matched to this page by NAME, which is weaker: measured 2026-08-30 across 625 portfolios, that name match succeeds for about 91% of funds, because the AMC's file carries no AMFI scheme code. A fund with no match simply shows no holdings section rather than another fund's. One disclosed portfolio also covers every plan and option of a fund at once, since that is the granularity the fund house publishes at.

Active share (Cremers & Petajisto, 2009) is half the sum of the absolute difference between this fund's disclosed weight and the benchmark proxy's disclosed weight, security by security. Tracking error (Roll, 1992) is the annualized standard deviation of the daily difference between this fund's return and the proxy's, over the days both have a stored NAV. Neither is a rating or a score; both describe how much this fund's actual holdings and returns differ from a portfolio that simply held the benchmark.

StockProof has no official total-return index (TRI) data — the price feed it stores tracks an index's PRICE only, which understates a real TRI benchmark by roughly its dividend yield. Instead, both figures are computed against another fund: an index fund that tracks the same benchmark, whose own NAV already reflects reinvested dividends and whose own disclosed portfolio stands in for the benchmark's constituent weights. Measured directly: two different index funds on the same benchmark differ from each other by only 2–3 basis points a year of tracking error — two orders of magnitude below any actively managed fund's real figure — which is what licenses using one as a stand-in for the true benchmark. This proxy is hand-picked and verified for 24 declared benchmarks; a fund benchmarked to anything else shows no active share or tracking error, not a guessed one.

Tracking error is computed over whatever NAV history both funds actually share, which is genuinely short — AMFI's history file starts no earlier than April 2006, but the DEPTH stored here reaches back only to around September 2023, roughly three years, well short of the five-year-plus history stock pages elsewhere on this site commonly show. The exact window and day count are shown beside every figure so it is never mistaken for a longer, more settled estimate.

Higher active share means this fund's holdings differ more from the benchmark proxy; lower means they resemble it more closely. Neither direction is automatically better or worse — it depends on what the fund is being held for and whether that difference is deliberate stock-picking or an accident of the universe boundary this data can see. The same is true of tracking error: a fund built to closely track its benchmark should show a low one, while a genuinely active fund is expected to show a higher one by design. This is descriptive, not a recommendation to buy, sell or hold anything, and nothing on this page ranks or scores funds against each other.

A single day whose NAV changes by an implausible amount — almost always an unrecorded corporate action such as a unit split, not a real market move — is detected and the whole tracking-error figure is withheld for that fund rather than shown corrupted by one bad day. Active share is unaffected by this check: it comes from the fund houses' own disclosed portfolios, not from NAV history.
