How to analyze Japanese stocks with AI

AI can organize financial and share-price data into questions and scenarios. Its output depends on the underlying data and should be checked against sources.

A five-step approach

Start with operating performance, then examine financial health, valuation, peer comparison and risks.

  1. Review revenue, operating profit, margin, ROE and ROA.
  2. Compare equity, debt, cash and operating cash flow.
  3. Evaluate P/E, P/B and dividend yield in context.
  4. Compare several years and similar companies.
  5. Read the evidence, assumptions and risks behind any AI summary.

What the score means

J-KABU's Pro features include an 11-part SCORE and evidence-based analysis. A score summarizes selected inputs; it does not predict returns or replace review of filings. Some data can be delayed or unavailable.

Common mistakes

Do not treat a generated explanation as a verified source, infer certainty from a single score, confuse forecasts with facts, ignore missing data or overlook changing market conditions.

Market and financial data may be delayed. Verify original company filings and make your own investment decisions.
