About this site

KabuDo is an independently run information site that breaks down U.S. publicly traded companies— business model, six years of financials, capital efficiency (ROIC vs. WACC), earnings quality, strengths and weaknesses, and risks—into diagrams and charts. Companies are added in batches, in the order shown on the home page. This site is not affiliated with the U.S. Securities and Exchange Commission, any stock exchange, or the companies it covers.

Who runs this

KabuDo is run by an individual. I began investing in stocks in earnest in 2008 and today manage a portfolio of Japanese stocks, U.S. stocks, Vietnamese stocks, and mutual funds.

Why I built this site

A company’s overall picture is very hard to grasp from Form 10-Ks and other filings. Some things are hard to see, or easy to miss, just by reading the financial statements. I built this site to lay out the information I want to see, visually and in a form that’s easy to read, because organizing it this way can show what wasn’t visible before and help with investing.

How to use this site

I built this site to find good companies to invest in, so a wrong figure would be a serious problem for me. I have other AIs check the content as far as possible, and I set it up so that anything can be confirmed in the primary source when needed. Reading these analyses also shows me things I hadn’t seen from the primary documents alone, so I use the site for my own learning too.

You don’t need to trust what’s written here. Use it first as a tool for getting the overall picture of a company, and do the detailed analysis yourself.

How I think about investing

In my experience, companies that can’t earn steadily tend to see their share prices struggle to rise. I think holding a company that grows over the long term ends up giving a better dividend yield than buying a high yield today. I also suspect that companies with strong brands tend to recover more easily after their shares fall.

This comes from my personal experience. I haven’t tested it against data, and it isn’t a recommendation to buy or sell any stock.

How to read a company page

If you read along those lines, this order works well:

  • Does it earn steadily? See “Six years of financials” for the sales and profit trend, and “Earnings quality” for whether profit is backed by cash.
  • Can it keep growing? See “Business model” for how it makes money, and “Is ROIC above WACC?” for how efficiently it uses capital.
  • Where does its strength come from? See “Strengths & weaknesses”, “Competitors & peers” and “Flagship products & services”.
  • What could go wrong? See “Risks” and “Legal & regulatory matters”.
  • Check anything that matters in the original: each page links to the 10-K and other filings.

Where the data comes from

Financial figures are pulled automatically from SEC EDGAR’s XBRL company-facts API, sourced from each company’s Form 10-K. Every period’s figures link back to the original filing on EDGAR so readers can check the primary source at any time. Where a later filing restates a prior period, the restated figure is used. Each company’s earnings calendar — quarter-end dates, earnings release dates, and 10-Q/10-K filing dates — comes from SEC EDGAR’s filing history. Stock prices, used to compute beta (against the S&P 500 ETF, SPY) and year-end P/E, come from Yahoo Finance’s public price data. The risk-free rate used in WACC is the latest 10-year yield from the U.S. Treasury’s daily par yield curve, and ownership figures come from the SEC Form 13F data set and each company’s proxy statement.

How the analysis is put together

The business model, strengths/weaknesses, risks, and other write-ups are written by AI from each company’s SEC filings (Form 10-K, 10-Q, and 8-K) and the company’s own press releases, then checked by several other AIs, and corrected when something is found to be wrong. The aim is to include nothing these sources don’t support, but errors can remain, so check the original before an important decision. Where a section gives this site’s own reading — for example, what an acquisition was meant to achieve — it is labeled as such and built only from sourced facts. Every computed figure (ROIC, WACC, earnings-quality metrics, etc.) is shown with its formula and a worked example using that company’s own numbers, so nothing is a black box. Full formula detail is in How to read this.

How each analysis is checked

Before a company is published, its six years of XBRL figures are compared with the 10-K statements: jumps, sign flips, missing years and stock splits are flagged and either corrected from the filing or left blank. Every correction is listed on the company page with its reason and source, and years that can’t be compared (for example, before a spin-off that was never restated) are dropped with the reason shown. Written statements are checked against the filing text by several AIs, and the page is built and checked before it goes live. Quarterly 10-Qs and material 8-Ks are added as they are filed.

What this site does not do — limits to keep in mind

It does not forecast earnings or give price targets. Computed figures follow the formulas in How to read this and can differ from figures defined differently elsewhere. Impact and likelihood on the risk map, and sections marked as this site’s reading, are judgments, not company statements. XBRL data can contain the filer’s own tagging errors, and ownership and price-based figures are as of the dates shown. Banks, insurers and other balance-sheet-driven financial companies are not given ROIC, WACC or FCF-based measures. Coverage is still partial: the home page shows how many listed companies are covered so far.

How this site is funded
