What this tool returns
Returns daily PER, PBR and dividend yield of one stock, computed from the split-adjusted close and the EPS, BPS and dividend per share of the latest fiscal period disclosed by that day. basis=fy (default) uses annual figures; basis=ttm uses trailing-12-month EPS and the latest quarter's BPS. PER is null when the company has a loss. A single request covers at most 10 years, and prices start on 4 January 2010 (or the listing date for stocks listed later).
Description sent to AI clients

PER is null for losses; yield is a decimal (0.03 = 3%). Defaults to the last year; max 10 years. 株価と決算（EPS・BPS・1株配当）から計算したPER・PBR・配当利回りの日次推移。Costs 10 tokens.
