“Inside the indexes” 4/5: rebalancing day, seen inside an ETF
Fourth instalment of the series: the logistics of the day an MSCI index changes shape — the countdown from announcement to effect, the weight freeze, why everything happens at the close, and the rules already written for mishaps. With an ending only our data could provide: SWDA's basket photographed before and after the August 2026 review — 10 stocks in (led by SanDisk), 32 out worth 0.26% combined, a single weight adjusted beyond the threshold. Per €10,000 replicated, all the move's sales are worth €26.

Rebalix has a new homepage: all the tools, finally on a single path
We redesigned the homepage to show Rebalix for what it has become: a single place to search ETFs and bonds, understand investing starting from official sources, use free calculators and monitor your portfolio. The new page brings together the census of ETFs, ETCs/ETPs and funds, more than 83,000 government, supranational and corporate bonds, the guides, the calculators and the portfolio app in private beta. And it makes more visible what holds everything together: sources preserved, reproducible calculations and missing data declared. It is not just a new entrance to the site. It is the complete map of Rebalix.

Franklin Templeton is the twelfth issuer in our census
48 ETFs join, read as always from the issuer's official sources: full NAV series since launch (2017), distributions with ex, record and payment dates, holdings updated daily, assets certified by the Irish ICAV's financial statements, and documents in Italian and English. The range declares 37 index-tracking ETFs and 11 actively managed ones — for the latter, the benchmark shown on our pages is a yardstick for comparison, not an index being tracked. Fund pages, histories and white-list shares are already live.

New guide: accumulating or distributing ETFs?
The answer you read everywhere — “accumulation defers taxes” — is only true in some countries. The new guide takes the choice apart in three pieces: the maths (proved on real data from the Vanguard VWCE/VWRL pair: 244.1 versus 244.1 with payouts reinvested), the research on investor behaviour (only replicated or never-refuted studies) and the tax treatment across nine European countries read from official sources. With the deferral map, the four-country example and the animated “race” chart.

White list: Fidelity tax ratios updated for the second half of 2026
Fidelity has published its white-list document for the second half of 2026 and the tax ratios of its ETFs are already updated across fund pages and app estimates: the government-bond share that brings Italian taxation below 26% comes from the same semi-annual document your broker uses. As always it is an estimate to confirm on your statement: the net amount applied by your broker is what counts.

Every ETF gets its history page: fund assets year by year, from audited financial statements
Every fund page now has its own “History” page: the fund-assets (AUM) chart with tooltip and zoom, plus a monthly snapshot of the basket. And the history does not start today: we brought it home by reading the SICAVs' audited annual and semi-annual reports — back to 2019 for some issuers, over 3,100 asset data points, each with its source. The same reports also give us the tracking difference the issuer declares, class by class: double-checked sources now cover five issuers and over 2,000 funds, agreeing with our own calculations in 97–99% of cases — and where the comparison reveals a fund changed index over time, our TD starts from the year of the switch. Finally, the UBS census moved to the full European range: +187 share classes (Hong Kong, TIPS, the CHF- and GBP-hedged ones) for investors in Switzerland and the UK.

Dividends on the fund page: 26 years of distributions, yearly yields — and tracking difference now reaches distributing share classes
Distributing funds get a new Dividends section: the complete payment calendar with all three dates (ex-date, record, payment), the dividend yield year by year and its share of total return, in 11 currencies at ECB rates — with the terms explained right on the page, no need to leave the fund sheet. And tracking difference now covers distributing classes too: where the issuer does not publish a dividends-reinvested series, we rebuild it by reinvesting each distribution on its ex-date, with the method verified against official issuer series. All of it flows into the printable fund sheet and the ETF comparison report as well: TD and dividend yields included, ready to bring to your advisor or bank.

“Inside the indexes” 3/5: who governs MSCI indexes
Third instalment of the series: who writes the index rules. The committees that decide (no individual decisions, by policy), the public consultations whose outcome does not bind MSCI, the 50-basis-point rule on calculation errors, the three criteria that make a country “developed” and the conflicts of interest MSCI itself declares in its own documents. As always: everything from the official policies read in full, with the EU regulation's origin verified against the legal text.

“Inside the indexes” 2/5: how a stock gets into (and out of) an index
Second instalment of the series: the mechanics nobody covers, read from MSCI's official rulebooks. The three filters that decide who gets in (size, float, liquidity), the asymmetric buffer that keeps index churn below 3% a year, the three staggered snapshots behind every quarterly review — including the price one, taken on a day MSCI does not announce. Then the fast lanes (very large IPOs join after ten trading days) and the three exits: the acquired leaves at full price, the bankrupt leaves the same day, the one suspended for fifty days leaves at 0.00001. With four new diagrams and what it all means, in practice, for anyone holding an ETF.

Bond ETFs: duration, credit rating and maturities as declared by the issuer, on every fund page and refreshed monthly
Every bond ETF page (government, corporate, aggregate, high yield…) has two new sections, reachable from the «Duration» and «Rating» menu items. The first shows the duration — with the type the issuer uses (effective for iShares and SPDR, modified for Amundi, UBS, LGIM and Xtrackers, average for Vanguard and JPMorgan: we never harmonise them) and the portfolio breakdown by maturity bucket; the second the breakdown by credit rating, with the scale and buckets of the original document. All values are read from the monthly factsheets we archive or from the official product pages, never computed: each section states the document's reference date. No «average maturity» and no «yield to maturity»: they depend too much on currency, hedging and definition to sit in an honest comparison. Coverage at launch: duration for nearly all of the ~950 bond ETFs in the registry, charts for the issuers that publish them (sections only appear where the data exists). Refreshed automatically twice a month by the registry runner.

Active or passive management: its own filter, for every issuer — and replication declared even where the listing is silent
Until yesterday “active management” was an option inside the Replication filter, and the replication method was missing for half the screener (Xtrackers, Vanguard, JPMorgan, LGIM and a quarter of iShares don't expose it in their listings). Management is now a field of its own — “Active management” or “Passive (index-tracking)” — read ONLY from declared data: the issuer's structured field where it exists (iShares, Invesco, Avantis), otherwise the KID objectives (“actively managed”, “passively managed”, “tracks the performance of the index”), and as a last resort the listing exchange's classification. The fund name never counts: it is only the sentinel that warns us if an “Active” is left without a source. With the same method, replication (physical, sampling, optimised, swap) is now declared for 800+ more funds, labelled “from the KID” where it comes from there. An active ETF can therefore be, correctly, “active management” AND “physical replication”: they are two different questions. The “Management” filter sits under “How it works”; every fund page shows both values with their source.

Invesco joins the screener: the eleventh issuer, with 24 years of EQQQ history
Invesco's 294 UCITS share classes — from EQQQ on the Nasdaq-100, listed since December 2002 and among Europe's longest-running ETFs, to fixed-maturity BulletShares, AT1s and AAA CLOs — are now in the screener with a full fund page: daily NAV series since launch together with the index series declared by the issuer (hence year-by-year tracking difference from a primary source), full holdings, KID and factsheet in Italian and English, KID transaction costs, risk indicators, savings-plan simulator. For distributing funds we show the reinvested-dividend return — the real one, not price alone. Before publishing, three days of checks: TER, returns, volatility and drawdown compared with international comparison sites on 50 funds, tracking difference on another 46, white-list share reconciled with the current half-year; where a figure did not add up we suspended it rather than publish it.

“Inside the indexes”: the MSCI World guide opens the blog's new series
Almost nobody has ever read the rules that govern the index European portfolios replicate the most. We read them all — from the 192-page construction rulebook to the committee policies — and distilled them into the first instalment of a five-part series: who decides which stocks get in (and who is excluded), why the US weighs 72%, what changes between the Price, Gross and Net flavours of the same index, and who profits from the index machine. With charts refreshed at every monthly MSCI factsheet: country and sector composition, top-10 concentration, valuations. Coming next: how a stock enters and leaves an index, who governs indexes, rebalancing day, and Net/Gross/Price in full depth.

Avantis joins the screener: the tenth issuer, at a reader's request
The six UCITS ETFs by Avantis Investors — the firm founded by former Dimensional senior leaders, known for systematically active factor strategies at low cost — are now in the screener with full pages: daily NAV series since launch, complete holdings (up to 4,100 positions), risk indicators, recurring-plan simulator. Including Global Small Cap Value (AVWS), over $1.2 billion gathered in under two years. It is the first issuer added at a reader's suggestion: if the screener is missing something you use, write to us. Holdings are not a one-off snapshot: from the moment an issuer is covered, the system archives them automatically every month, and as history builds up the fund pages will show the main changes — country and sector weights, portfolio — especially useful for actively managed funds, where portfolio moves reveal the manager's choices.

Government bond ETFs: each fund's real tax rate, not “26%”
The comparison-page series closes with the government bond hub: 340 UCITS classes area by area (Eurozone, US Treasuries, Europe, global, inflation-linked in their own section) with the number no comparison site shows — each fund's effective Italian tax rate, weighted on the white-list share the issuer certifies every semester. Median: 12.81%, not 26%. Tables also carry maturity bucket (the rate-risk lever), TER, tracking difference and assets, from official documents re-read monthly.

World & global ETFs: four families compared — and “World” doesn't mean the whole world
The global equity page is live, built around the thing most people searching “World ETF” never learn: MSCI World covers developed countries only — no China, India or Brazil. Four families in separate sections (MSCI World, ACWI with emerging markets, ACWI IMI with small caps, FTSE All-World) and a number no comparison site shows: the median tracking difference per family, measuring what wider coverage really costs. Census tables with TER, KID costs and assets, FAQs on the real differences (even South Korea, “emerging” for MSCI and “developed” for FTSE), refreshed monthly.

Gold in ETFs and ETCs: physical, miners, and the tax angle few explain
A dedicated gold page is live: physically-backed ETCs and miner funds, kept separate as they deserve — the latter are equities, not metal. Inside: why in Europe physical gold must live as an ETC (UCITS rules forbid a single underlying), the tax difference that follows under Italian rules — ETC gains offset carried-forward losses, including those from shares and ETFs sold at a loss —, the “denominated in euro doesn't mean hedged” trap, and the true cost measured by tracking difference: hedged classes show the price of the hedge. Census tables with TER, KID costs and assets, refreshed monthly.

S&P 500 ETFs: the full comparison of the most-searched index
A dedicated page for S&P 500 ETFs is live: 50 core UCITS share classes (ESG, sector and leveraged variants excluded), €745 billion in combined assets. At its heart, the physical-versus-swap comparison measured on 12-month tracking difference — not the TER — with the why: the 15% withholding on US dividends that physical funds face and swap structures can avoid. A table of the 25 largest classes with KID costs, TD and assets, FAQs on accumulation, NTR and currency hedging, Italian taxation. No rankings: the numbers, fund by fund, from official documents re-read monthly.

ETF Screener: the engine with the data others don't show
The ETF Screener is live: 2,600+ ETFs and ETCs from 9 issuers with 28 filters organised by question — what it costs, how solid it is, how it works, where and how. The table shows what almost no comparison site exposes: KID transaction costs next to the TER, the 1-7 KID risk indicator, securities lending, the Italian white-list tax share and a 12-month chart. Every row links to the fund's full page, with year-by-year tracking difference, 100% holdings where the issuer publishes them and inflation-adjusted real returns. Every number comes from official issuer documents, automatically re-read every month: where a value isn't declared you see a dash, never an invention.

Tracking difference: an ETF's real cost, explained and searchable
The TER says what an ETF should cost; tracking difference says what it actually cost. The new page explains it in plain words and lets you look it up for 1,400+ ETFs, computed from primary-source series with a declared methodology: total return or accumulating classes, never a distributing class's NAV, and a sanity net that discards inconsistent comparisons. The yearly returns we compute match the sector's international references — and every fund page shows the year-by-year series next to the TER.

Provider pages: who is behind your ETFs
Nine pages, one per investment house — from iShares to 21Shares — with the history, what sets each apart and the real numbers from our census: fund count, assets, median TER, median tracking difference and how much of the range declares securities lending. Statistics that recompute themselves with every monthly data run, not brochures. From each page you reach the issuer's full range in the screener, already filtered.

Guide: the C3M money market ETF — declared vs measured costs
The second guide in our money market ETF series is live: Amundi's C3M, the fund that buys the short-term government bills of 7 eurozone countries. The central finding, measured on 9 years of official NAVs: the KID estimates costs at 0.25% per year, but the measured fund–index gap is 15 basis points — essentially the TER alone — and the reason is written in the index construction rules. With an interactive XEON comparison over custom periods, the drawdown since launch (2009), the basket map, what is left after Italian taxes depending on the semester you sell in, and a method note under every chart. All data updates automatically, every day — and with this guide our Money market ETFs section is born.

Guide: physical or synthetic replication — what your ETF really owns
Our reference guide on ETF replication is live, with data you will not find elsewhere: inside a large synthetic S&P 500 ETF we measured, on the issuer's official lists, a basket with almost a third of non-US holdings and a 56.5% active share — and we redid, on the MSCI World, the comparison Vanguard published in 2019. With the UCITS rules explained from primary sources, the US withholding savings of synthetics, per-country taxation (Italy, Germany, France, Switzerland, UK) and the XEON case: Italy's white-list share is computed on the basket, not the index.

Public database: taxation and white-list share of 1,700+ ETFs
Our white-list share search engine is live: look up your ETF by ISIN, ticker (across 6 European exchanges, from Milan to Xetra) or name, and get the government-bond share certified by the issuer, the effective Italian tax rate already computed, and worked euro examples on gains and distributions. Every page states its source and validity semester, flags newly launched funds (transitional 26%) and data awaiting the new semi-annual report. We cover 11 issuers — from Vanguard to JPMorgan — and honestly say who's missing and why. Free, no sign-up.

Coupon and dividend net amounts, prefilled from official sources
In Settings (and during onboarding) you can now declare your tax residence. If it's Italy, Rebalix prefills the estimated net of your income: 12.5% on white-list government bond coupons, 26% on Italian stock dividends and — for over 10,000 ETFs from Vanguard, iShares, Amundi, Xtrackers and Invesco — the effective rate derived from the white-list documents issuers publish every six months: the same source your broker uses. It's always an estimate to confirm, never a computation of your taxes: the real net from your statement is what counts. Without a declared residence nothing changes — you see gross amounts as before.
