Why there are no buy/sell ratings

Sites that publish ratings work because many independent authors argue with each other, readers contest them in the comments, and each author's record is public. kstock has none of those three yet. A single writer handing out verdicts without them is not a product. So kstock stops one step earlier: it says what happened, how big it is relative to revenue or market cap, why it is unusual, and what would tell you the answer next. The decision stays with the reader.

Three levels, and where kstock sits

Rules the writing follows

• No number that isn't in a sourceContract values, market shares, targets — if the filing or the article doesn't say it, it doesn't appear.
• Everything converted to an investor's unitA contract becomes a share of revenue. A buyback becomes a share of market cap. A capex line becomes future depreciation.
• Filings beat articlesWhen a newspaper figure and a DART figure disagree, the filing wins and the disagreement is stated.
• Won and dollars togetherat an approximate rate that is labelled approximate.
• Korean market mechanics get explainedthe ±30% limit, KRX inquiry disclosures, the statutory cancellation rules — not assumed.

Factor Grades

Five factors, graded A+ to F, shown against the same company three and six months ago. They are computed from DART filings and KRX closes — arithmetic, and the inputs are printed next to each row. They are not a recommendation and not a forecast. The scoring model is not final; the grades on the site today are illustrative.

Which filings get written up

Korean issuers file a great deal that no one needs to read — IR schedules, meeting notices, routine insider forms. Every filing gets its title translated and a link to the original. A filing gets a written explanation when it moves money or control at a scale that matters against revenue or market cap.
