One of the app's features lets you select WisdomTree ETFs in the Watchlist and aggregate their holdings to see how often each ticker appears across the selected funds. Repeated holdings make overlapping exposure visible: the more selected funds include a ticker, the greater its potential influence on the portfolio; gains in that holding may help, while declines may hurt, and actual impact also depends on each fund's position size. Another feature makes it faster and easier to find funds with stronger growth over different periods, higher dividend yields or distributions, greater Total Return (price performance plus dividends), and other key performance metrics. A single-file client-side tool reading the generated ./api/wisdomtree static feed (WisdomTree product pages - including official Market Price/NAV/Underlying Index returns and the official tax-character distributions table, SEC EDGAR N-PORT-P holdings, Yahoo Finance history with a narrow distributions/returns fallback) into a searchable ETF/asset-class catalog with per-fund tabs, watchlist, N-PORT upload, CSV/TXT export - the same look, feel, columns and business logic as the sibling applications.

Every column of the ETF catalog and of the Watchlist, Holdings, History and Distributions tabs has a type: text (ABC), number (123), percentage (%), money ($), date (D), date and time (DT) or time of day (T). The type is detected from the texts the column shows (80% of the filled cells must agree, otherwise text) and is written in the badge next to the column title: click it to cycle the type, Shift+click to return to auto-detection. Dates are read as 2024-06-15, 6/15/2024, 15.06.2024, Jun 15, 2024 or 15-Jun-2024, date and time as 2024-06-15T09:30:00Z or 2024-06-15 09:30, time as 09:30, 16:00:00 or 9:30 PM
A row of filter inputs sits under the column headers (the Filters button hides it, Clear filters empties it). Filters of different columns are combined with AND, the search box applies on top, and Copy Tickers and the exports use the filtered rows. Filters and type overrides are remembered in the browser. Sticky # (next to Filters, off by default, remembered in the browser) numbers the rows by their rank in the table sorted by the current column before the column filters, so a filtered fund keeps its rank and the numbers keep gaps; the sort, the search and the category and blacklist choices rank again. The catalog starts sorted by Net Assets, largest first, unavailable values sort last in both directions, and every export starts with the # column. The red Clear button forgets everything saved in the browser without asking, except the blacklist and the theme, so the page looks like a first visit (also after a reload)
Inside one filter: a space means AND, a comma means OR, a leading ! means NOT, ? matches an empty or unavailable value and !? a value that is there; a value that is unavailable matches only ? and negated conditions. An unquoted space ends the value, so quote values that contain one (>="2024-06-15 09:30")
| Type | Examples |
|---|---|
| Text | bank contains, "two words", !bank, =exact, ^starts, ends$, /regex/, tech, health |
| Number, percentage, money | >10, >=10 <50, =22 (matches what rounds to 22), !=22, 10..50, ..50, 10.., >1B and K M B T suffixes, an optional $ or % |
| Date, date and time | >2024-06-01, 2024 (the whole year), 2024-06 (the whole month), 2024-01..2024-06, today, yesterday, -7d.. (the last 7 days), +2w, -3m, -1y |
| Time | >09:30, 09:30..16:00, =12:00 (the whole minute) |
The Columns menu next to Filters lists every column of the ETF table from the first to the last, all of them shown by default, with a search box and the All, Clear, Toggle and Reset buttons. Use and Ticker are listed but locked. Hiding a column only removes it from the table: the filters, the sorting, the exports and Copy Tickers still use it. The choice is remembered in the browser (localStorage, never the data) and the menu is shown on the ETF catalog only
The asset classes are one Asset classes multi-select next to the All ETFs pill instead of one tab per class: every class is selected by default (= all ETFs), Only or unchecking narrows the table, and the All ETFs pill is lit only while nothing narrows it (all or none of the classes checked); clicking the pill clears the selection. The choice is remembered in the browser (localStorage, never the data)
Run the updater with Bun:
bun scripts/update-data.tsRun bun scripts/update-data.ts -h (or --help) to print every control with its default and usage examples.
Defaults live in scripts/update-data.config.json. Precedence: file defaults < advanced JSON < nonblank workflow inputs < protected Actions variable or environment variable. A blank input inherits the file value, and the CLI and the Update WisdomTree ETF data workflow share one resolver (resolveControls in scripts/update-data.ts). The workflow exposes 24 controls as individual inputs; every other control (HOLDINGS_PAGE_SIZE, STORE_RAW_DOWNLOADS, SEC_UA, VERBOSE, USE_SYSTEM_CA) is reachable through the advanced JSON input, for example {"STORE_RAW_DOWNLOADS":"true"}. An explicitly set environment variable always wins, even when empty. The protected SEC_UA repository Actions variable overrides the SEC contact when nonblank. Output is always written to api/wisdomtree. All supplied filters use AND logic.

| Access path | wisdomtree.com is Cloudflare-protected. Each page is tried directly once (a block latches for the rest of the run), then through the read-only r.jina.ai rendering: one global gate (at least 3.2 s between starts), at most one retry, and a verification page counts as a failure. Only the SEC receives the SEC_UA contact; other hosts get a generic User-Agent |
Each fund carries a derived metrics object that powers the catalog columns shared with the sibling sites:
-
ytd/tr1y- official YTD and 1-year returns -> YTD Return, TR 1Y -
cagr3y/cagr5y/cagr10y- published annualized 3Y/5Y/10Y figures -> CAGR 3Y/5Y/10Y -
tr3y/tr5y/tr10y- cumulative 3Y/5Y/10Y figures(1 + CAGR)^n - 1-> TR 3Y/5Y/10Y -
siAnn- since-inception annualized -> SI Ann.; derived only for funds with at least one year of history -
dividendYield- 12-month trailing yield or indicated yield (latest distribution x frequency / price); a catalog 0.00% is the provider's published value and is kept as published (yields.dividendYieldKindsays so) -
dividendYieldBasis- code of the definition behinddividendYield,nullexactly whendividendYieldisnull; it travels with the yield (a retained yield keeps its code):Code Meaning for WisdomTree official-trailing-12mtrailing 12-month yield published in the WisdomTree product catalog (a published 0.00% included) indicatedupdater estimate: latest distribution x inferred payments per year / market price, used when the catalog has no yield The codes
official-distribution-rate,official-otherandcomputed-trailing-12mof the shared standard are not produced by this updater -
secYield- 30-day SEC yield when published; unavailable values stay empty and are never shown as 0 -
returnsBasis- mandatory non-empty text saying how the returns were computed: official WisdomTree month-end Market Price Returns (gaps filled with Yahoo estimates), or estimates derived from Yahoo adjusted closes when the product page is unavailable -
performanceAsOf- mandatory ISOYYYY-MM-DDdate the returns are as of: the WisdomTree month-end performance table date, or the last Yahoo close date when derived (not the NAV date);nullonly when truly unknown -
NAV and the catalog figures come from WisdomTree; history and returns derived from Yahoo adjusted closes are market-price estimates, not official NAV returns
-
When the product page cannot be fetched, the previous official returns, quarter-end returns, distributions table, NAV, market price and premium/discount are kept together as one unit (with their own dates and basis); they are never replaced by Yahoo estimates or mixed with a fresh price.
meta.jsonsource.productPageStatussays which case applied. A page that is fetched but publishes no quarter-end table leaves quarter-end empty (asOfDate—) -
A product page that loads only partly (the r.jina.ai rendering proxy sometimes drops sections) counts as a failed read of the missing sections: the page is complete only when it has the pricing tables (NAV, Closing Market Price) and the Total Returns section. Each missing section (NAV/price/premium, returns with
performanceAsOfandreturnsBasis, distributions with the tax breakdown) keeps the previous official values as one unit and a[ kept ]line is printed withVERBOSE; a fully loaded page that lacks a field gives an honestnull, never a refill from the previous run -
Expense ratio:
terValueis the net expense ratio (after waivers),terGrossValuethe gross ratio from the catalog; both arenullwhen unknown -
isinis derived from the CUSIP (US prefix plus check digit) because the pages do not publish it;cusipstays empty for the few funds whose page lacks it, andexchangecomes from Yahoo and stays empty when Yahoo is unavailable -
A limited
HISTORY_RANGEshortens the published history, so long-tenor figures derived from Yahoo are unavailable for ranges shorter than the tenor
Every control is a key in scripts/update-data.config.json; values are strings.
| Control | Default | Meaning |
|---|---|---|
MAX_FETCHES |
0 |
Batch size over the funds that pass TICKERS/AUM/TER/DIVIDEND_YIELD: with a positive value the updater continues after the committed cursor in api/wisdomtree/update-state.json (in ticker order, wrapping around; the cursor moves past every fund taken, whatever its outcome); 0 is a full pass. A TICKERS run never touches the cursor. |
REQUEST_SLEEP |
2 |
Minimum delay in seconds between outgoing request starts, including retries. |
CONCURRENCY |
2 |
Number of parallel fund update workers, each with its own request pacing lane. |
AUM |
: |
Net Assets range. Each bound may be a USD amount or K/M/B/T, or one of nano, micro, small, mid, large. |
TER |
: |
Expense ratio range in % (strict min:max). |
DIVIDEND_YIELD |
: |
Dividend-yield percentage range. |
SEC_YIELD |
: |
30-day SEC yield percentage range (strict min:max), read from the product page; funds without a published SEC yield do not match. |
TICKERS |
empty (all) | Space-, comma- or semicolon-separated ticker allowlist, e.g. DGRW USFR WCLD. |
HOLDINGS_PAGE_SIZE |
250 |
Rows in each generated current-holdings JSON page. |
HISTORY_PAGE_SIZE |
1000 |
Rows in each generated daily-history JSON page. |
MAX_RETRIES |
2 |
Retries after the initial request (integer, at least 1). Network errors and HTTP 403/408/425/429/5xx are retried with exponential backoff. |
HISTORY_RANGE |
max |
Yahoo history window: max or a whole number of years such as 5y; sent as explicit period1/period2 (Yahoo ignores range when period1=0). Anything else is an error. |
STORE_RAW_DOWNLOADS |
false |
Store the rendered official catalog under data/raw/ (outside api/wisdomtree, so the workflow never commits it). |
EDGAR_FALLBACK |
true |
Use SEC EDGAR Form N-PORT-P for full holdings. |
SKIP_YAHOO |
false |
Keep previous history and distributions while refreshing catalog and holdings. |
SKIP_WISDOMTREE |
false |
Keep the previously published official catalog. |
SEC_UA |
daggerok ETF feed daggerok@gmail.com |
User-Agent for SEC requests only (other hosts get a generic agent). SEC policy asks automated tools to declare a contact; the protected SEC_UA Actions variable overrides the default. Redacted in logs. |
VERBOSE |
false |
Print per-fund retry and fallback notices. |
USE_SYSTEM_CA |
auto |
TLS trust store: auto restarts the updater once with Bun's --use-system-ca when a request fails with an untrusted-certificate error; true always uses the system CA store; false never restarts. Not an individual workflow input: use advanced, the config file or the CLI environment. |
PERFORMANCE_YTD / _1Y / _3Y / _5Y / _10Y |
: |
Annualized adjusted-close return range per tenor: min:max. |
TOTAL_RETURN_YTD / _1Y / _3Y / _5Y / _10Y |
: |
Cumulative adjusted-close return range per tenor: min:max. |
Environment aliases: WISDOMTREE_<NAME> (for example WISDOMTREE_CONCURRENCY) and HISTORICAL_PAGE_SIZE (for HISTORY_PAGE_SIZE) work in the environment layer, the same layer as the plain name; when several are set the plain name wins, then WISDOMTREE_<NAME>, then the legacy alias. They are validated exactly like the plain names.
Unknown TICKERS are an error. Return filters (PERFORMANCE_*, TOTAL_RETURN_*) exclude funds whose value for a bounded range is unavailable. The run takes no new fund after 25 minutes and still writes the index; it exits non-zero when every fund failed or no fund got data from a live source. A rerun with identical upstream data changes no file. When the live catalog adds or drops funds the run prints NEW FUNDS: ... or DROPPED FUNDS: ... (also in the Actions step summary); dropped funds keep their published data. Files are written through a temp file and a rename, pages first, then meta.json, with stale pages removed afterwards.
TICKERS combines with the AUM, TER, yield and return filters using AND logic; it does not override them. Filtered or bounded runs (TICKERS, MAX_FETCHES, filters, SKIP_WISDOMTREE) and runs where the live catalog could not be read never shrink the feed: funds that were not refreshed keep their published row and files, and index.json always lists every known fund (the published index plus every funds/*/meta.json).
