Measured tools (6)

• screen_company read-only

  Screen one company against all four standards. Returns a 'say' sentence, the live price, the consolidated share count, the filing figures used, the business screen per standard ('business': main_business, by_standard pass/fail/review, excluded_under), and each standard's ratio, threshold and verdict. In each screens entry, 'compliant' is the overall verdict (false when that standard excludes the company's business, null when the business needs a closer look) and 'debt_compliant' is the debt test alone. Verdicts within one percent of a threshold are flagged borderline. A company name (for example nvidia) also works.

  Parameters:

  • ticker (required) — string — US listing symbol (a common company name also works).

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_standards read-only

  The four standards, their denominators and thresholds. Screens a US-listed company against four published Shariah equity standards (AAOIFI, Dow Jones Islamic Market, S&P Shariah, MSCI Islamic), first on its business (prohibited industries each standard excludes) and then on its debt, using live...

• purify_dividend read-only

  How much of a dividend to give to charity. Returns the company's purification ratio (interest income over total revenue, from its latest 10-K that reports interest income; 'latest_annual_filing' and 'note' say when that is older than the latest 10-K) and, if a dividend amount is given, the amount to give to charity. For a company whose main business every standard excludes, 'business_screen' explains that purification does not make it permissible.

  Parameters:

  • ticker (required) — string — US listing symbol.
  • dividend — number — The dividend received, in any currency.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• find_halal_alternatives read-only

  Halal alternatives to a holding. Companies Mizan covers in the same industry (or the nearest related one) whose business is permitted and whose debt passes all four standards at the last quarter-end, largest first, plus Shariah index funds for US and UK investors. Screen a pick live with screen_company before buying.

  Parameters:

  • ticker (required) — string — The holding to replace: a US listing symbol or company name.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• screen_portfolio read-only

  Screen a whole portfolio. Screens up to 15 holdings under all four standards and returns the share of the portfolio that is compliant under each, the holdings that fail, and a combined dividend purification ratio.

  Parameters:

  • holdings (required) — string — Comma-separated tickers, each optionally followed by a colon and the value held, for weighting.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes
