DalsnaFinance › Data sources
This page lists where the data and text on Dalsna Finance come from, and what we use each source for. Each page also names its own sources, and figures in our profiles, guides and articles link to the document they come from. How we write and check our own pages is set out on our About page and in our editorial standards.
The US Securities and Exchange Commission's filing system. The financial statements on company pages come from the structured (XBRL) data companies file with the SEC. IPO pages are compiled from SEC filings, and our company profiles and articles cite the annual, quarterly and current reports (10-K, 10-Q and 8-K) their figures come from, with a link to each filing. Some figures come from a company's own earnings release instead, also linked and dated where used.

Market prices. Stock and index quotes, price charts, the daily closing prices used to judge analyst price targets and member calls, commodity price histories and dividend histories come from Yahoo Finance. When a company's SEC data lacks a figure, a few key statistics also come from Yahoo Finance. Prices can be delayed and are not meant for trading.

The earnings dates and economic events on our calendar come from Nasdaq's public calendars.

Headlines and summaries come from publishers' public news feeds (RSS), each credited to the outlet that reported it and linked to the original story whenever the feed gives an address on the publisher's own site. Some stories reach us through Google News search feeds; their links go through Google News to the publisher. Every publisher is listed on our sources page.

The price targets in our analyst tracker are taken from news reports of what research firms published, each with a link to its source. An AI model reads each target out of the report. A second, separate AI check then compares it with the source and searches other outlets' reporting for the same target. Only approved targets are shown or scored. While the automatic rules are switched on, a target that passes both checks and the site's own rules is approved without a person, and one that other reporting contradicts, or that the second check judges wrong, is rejected and never shown. A target the checks flag or cannot settle waits for a person to decide. The rules are on the methodology page.

Federal Reserve press releases appear in our economy news, and the dates of Federal Open Market Committee meetings come from the Fed's published calendar.

The figures in our tax, retirement, Social Security and Medicare guides restate what the Internal Revenue Service, the Social Security Administration and the Centers for Medicare & Medicaid Services publish, each cited and dated.

The supply figures on our crude oil, gasoline, heating oil and natural gas pages come from the EIA's weekly reports: U.S. crude oil, gasoline and distillate fuel inventories from the Weekly Petroleum Status Report, and working gas in storage from the Weekly Natural Gas Storage Report. Each figure is dated and linked to its release.

The crop figures on our corn, wheat, soybean, soybean oil, soybean meal, oats and rice pages come from the USDA's monthly World Agricultural Supply and Demand Estimates (WASDE): U.S. production and ending stocks, estimated or projected for the crop year, dated and linked to the report.

Our commodity explainers cite the exchanges that list the contracts (such as CME Group, ICE and the London Metal Exchange) and the issuers of the funds they mention.

The short company descriptions on company pages come from Wikipedia and say so, with a link. The S&P 500 and Nasdaq-100 membership lists and their change histories are checked against Wikipedia's lists, which follow the index providers' announcements. Company logos, where we show them, are image files hosted by Wikimedia.
