Five questions, answered for every stock.
Most stock sites hand you two hundred numbers and leave the conclusion to you. Ryufin works through the filings and answers the five questions an owner actually asks, one word each, with the checks behind every word one click away.

- 02Is it safe?Bankruptcy risk, the quality of the books, debt, insiders selling, how hard the price can fall.NVDA Mixed

- 04Is it growing?Revenue and earnings over years, the direction of the margin, what the next quarters imply.NVDA Excellent

Every answer shows its work.
A verdict you cannot check is an opinion. Under every word sits the list of checks it came from, each with its value, its date and its source, and the places where the checks disagree are named, never averaged away.
