The core metric from "My Investment Method" (2024), an unusual bestseller for an investing book in Japan. Net cash = current assets + investment securities x 70% - total liabilities (valuing investment securities at 70% to account for tax, the distinctive part of this definition). A ratio of 1.0+ means "you'd get change back after buying the whole company." Also reproduces the author's operating criteria of market cap under ¥50bn and PER under 10x. The definition differs from this tool's default net cash ratio, so it's worth comparing which names each one surfaces.

Data comes from annual securities reports disclosed on EDINET (Japan FSA). Price-related values are as of each company's fiscal year-end (back-calculated from the disclosed trailing PER), not live quotes. Coverage: all TSE-listed companies, with names added progressively.
Kiyohara-style net cash divided by market cap. 1.0+ is considered the level at which "you'd get change back after buying the whole company." (Source: Tatsuo Kiyohara, My Investment Method (2024))
Back-calculated from EDINET's own disclosed trailing PER x net income (per x net_income; since eps = net_income / shares, the shares term cancels out). Note this is the value as of fiscal year-end, not the current market price. (Source: This tool's core design)
Market cap divided by net income — how many years of earnings are priced into the stock. The PER used here is the trailing figure disclosed on EDINET (as of fiscal year-end), not the forward, estimate-based PER that brokers publish. In years when net income swings on extraordinary gains or losses the ratio goes to extremes, so it should be read alongside loss-year counts and the operating income trend.

Current assets + investment securities x 70% - total liabilities. Distinctively values investment securities at 70% to account for tax, unlike this tool's default net cash (which values them at 100% and subtracts only interest-bearing debt). (Source: Tatsuo Kiyohara, My Investment Method (2024))
