One stock

In this path sec stands for security, not the SEC: the file is one stock and the funds that hold it, and a fund's own holdings are in /api/v1/fund/{ticker}.json. Name, sector, market cap, valuation, returns, risk, the funds that hold it from issuer files and from SEC filings, and its weekly returns over the same 156 weeks as the fund files. Every stock in the price data with at least 110 weekly returns in those weeks has a file here, whether or not any covered fund holds it. A stock with fewer has one when a fund read from an issuer file or a stock ETF from SEC filings holds it in a file dated since it listed, the price data has its closes since its listing, or a year of them, the last at most five sessions old, and Nasdaq Trader's directory lists it under its name. weekly is then an empty list, the figures over three and five years and the correlated stocks are null or empty, calendar is given once 40 of the last 52 weeks have a return, and r1 once the weekly closes cover a full year. A security covered funds hold with no file of its own, a stock the price data does not list or lists too few weekly returns for, or a line listed abroad (7203.JP), answers with "coverage": "holders_only": its holders from the shard of its first character, each dated, the price and return fields null, and none of the fields built from each fund's file or the ledger, such as etf_ownership and holders_all. A 404 means no covered fund holds the key. Read coverage first: since October 2026, holders_only marks an answer without the fields Security requires and SecurityHoldersOnly does not list, such as etf_ownership, holders_all and answer.
