About

Global Stock Brief publishes independent US stock analysis built from SEC filings, plus a daily relative-strength (RS) rank of 129 sector and theme ETFs.

What this site does

Global Stock Brief started on August 30, 2026 and publishes two kinds of articles.

Daily sector RS brief. After each US trading session, the “Sector RS Rank” brief ranks 129 US-listed sector and theme ETFs by one-month relative strength. It lists the five leaders and the five biggest one-day gainers, flags funds whose rank broke down or rebounded sharply over five sessions, and names three stocks that passed a four-filter screen that day. Each brief ends with a price checkpoint for each stock and a calendar of the releases that matter next. How the RS rank works explains every table.

Single-company analysis. The longer articles take one company and rebuild its numbers from primary documents: Forms 10-K, 10-Q and 8-K, XBRL company facts, investor presentations and earnings-call transcripts. A typical piece covers five years of financials, the claims in the latest investor presentation, results against guidance, valuation bands, what sell-side analysts expect, and the line items in the next filing that would confirm or break the thesis. Each article closes with a “Methodology and Sources” section.

Who writes it

Global Stock Brief is written by one independent analyst who publishes under the site name. Figures in the company analyses carry a source label and, wherever possible, a link to the filing or company document they came from, so the work can be checked.

A Korean-language companion blog is published at blog.naver.com/investment_library.

Editorial rules

1. Every figure carries a source label. Numbers from a company document are marked “Company disclosure”, “Filing note” or “Filing footnote” with the document and page. Numbers the site computed are marked “Own calculation” with the inputs. Macro data are “Official statistics”, analyst estimates “Aggregated sell-side research” or “Aggregator check”, and press reports “Outside view”.
2. No price targets and no ratings. The site does not say buy, sell or hold and publishes no target prices. Where older articles use the words “stock forecast”, they refer to the checkpoints and conditions in the article, not to a prediction. A checkpoint is a level to watch, such as a prior closing high.
3. The scorecard is recorded as is. Each daily brief re-measures the previous brief’s three stocks against the S&P 500 over the same span and says which beat the index. Losing picks get the same space as winning ones, and past scorecards are never revised.
4. Figures are dated. Every article states the closing price and filing it uses, and a number is not updated when the price moves.
5. The filing wins. When a presentation and the 10-Q disagree, the article uses the filing and says so.

Data sources

• SEC EDGAR: Forms 10-K, 10-Q and 8-K with exhibits, proxy statements, Schedules 13D and 13G, Form 13F tables and XBRL company facts.
• Company investor relations sites: earnings releases, presentations, CFO commentary and call transcripts.
• Yahoo Finance closing prices for daily moves, moving averages and RS ranks.
• Aggregated sell-side research for consensus estimates, targets and ratings, reported as what analysts expect, not as the site’s view.
• For companies that do not file with the SEC, each article names the local disclosures used.

Corrections

When a published figure is wrong, it is fixed in the article and a dated note at the top states what changed. Typos that do not change a number are fixed silently. Report errors to smallcap5864@gmail.com.
