One of the app's features lets you select Fidelity 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 that reads the generated ./api/fidelity static feed (SEC EDGAR N-PORT-P holdings, Yahoo Finance price history and distributions) into a searchable ETF/category catalog with per-fund tabs, watchlist aggregation, N-PORT upload, ticker copy and CSV/TXT export — the same look and feel as the sibling applications.

Run the updater with Bun:
bun test scripts/update-data.test.ts
./scripts/update-data.tsRun ./scripts/update-data.ts -h (or --help) to print every configuration variable with its default and usage examples.
The Update Fidelity ETF data GitHub Actions workflow exposes the same settings as manual inputs. All supplied filters use AND logic.
| Block | Source |
|---|---|
| Catalog (all US Fidelity ETFs) | SEC EDGAR company_tickers_mf.json → Fidelity Covington Trust (CIK 0000945908) and Merrimack Street Trust |
| Holdings per fund | SEC EDGAR Form N-PORT-P primary_doc.xml (positions and net assets) |
| Daily history, distributions | Yahoo Finance public chart API (/v8/finance/chart/{TICKER}?range=max&interval=1d&events=div) |
| Fallback | company_tickers.json for ticker resolution of N-PORT positions |
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 1Ycagr3y/cagr5y/cagr10y— published annualized 3Y/5Y/10Y figures → CAGR 3Y/5Y/10Ytr3y/tr5y/tr10y— cumulative 3Y/5Y/10Y figures(1 + CAGR)^n - 1→ TR 3Y/5Y/10YsiAnn— since-inception annualized → SI Ann.dividendYield— 12-month trailing yield or indicated yield (latest distribution × frequency ÷ price)secYield— 30-day SEC yield when published;—otherwise
| Environment variable | Default | Meaning |
|---|---|---|
MAX_FETCHES |
all | Batch size: with a positive value the updater continues after the committed cursor in api/fidelity/update-state.json; empty or 0 is a full pass — every fund is refreshed in one run. |
REQUEST_SLEEP |
1 |
Minimum delay in seconds between outgoing request starts, including retries. |
CONCURRENCY |
2 |
Number of parallel fund update workers. Request starts are still globally spaced by REQUEST_SLEEP. |
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. |
TICKERS |
all | Space-, comma- or semicolon-separated ticker allowlist, e.g. FTEC FDVV FDIS FCOM. |
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. Only network errors and HTTP 408/425/429/5xx are retried with exponential backoff. |
SEC_UA |
declared UA | Override the SEC User-Agent. SEC policy requires automated tools to declare a contact. |
SKIP_YAHOO |
off | Skip Yahoo Finance history updates. |
TICKERS combines with AUM, TER, yield filters using AND logic; it does not override them. Funds not selected for a successful update keep their prior published metadata and data files.

PERFORMANCE_1Y="15:" ./scripts/update-data.tsThe browser app is intentionally build-free: index.html carries the markup, styles and bootstrap, and app.tsx is TypeScript compiled in the browser with Babel standalone — no build step, no bundler, no tsconfig.json needed. Bun runs TypeScript out of the box.
Verification before every publish: bun install --frozen-lockfile, bun test, and git diff --check.
