Stock overview

Read-onlyIdempotent

Overview of one US-listed stock: company facts (SEC name, CIK, exchange, SIC industry, other share classes), open-market insider activity in the last 90 days (Form 4 codes P and S, non-derivative: number of filings and total USD), institutional ownership from 13F for the latest complete quarter (number of holders, total shares and market value in USD, and the previous quarter for comparison), and the curated superinvestors holding it (shares, market value, pct_of_portfolio = percent of that superinvestor's 13F portfolio). A quarter is complete once its 45-day filing deadline has passed and the data is loaded; in_progress_quarter is a newer quarter still being filed. Share classes (GOOG/GOOGL, BRK.A/BRK.B) are separate tickers because 13F reports each class separately. A ticker that is no longer on the SEC's list (active false; delisted true when the company has no listed common stock left, with the Form 25 delisting date in delisted_on when known) keeps its page, and its 13F figures are for its last quarter with a full set of 13F holders (f13.note). financials summarizes the latest fiscal year and quarter (revenue, net income, free cash flow and their year-over-year growth, in the reporting currency, which is not always USD) and short_interest the latest FINRA short interest (short shares, change, days to cover); each is null when there is no data. market_cap is the company's market cap in USD. Market cap is the latest daily closing price of the company's primary ticker times the shares outstanding on its latest SEC 10-K or 10-Q cover page (shares_as_of), adjusted for stock splits since then (split_factor, 1 = none). It is recalculated every US trading day after the close; close_date is the trading day of the close used. No stock price is returned. When market_cap is null, market_cap_unavailable gives the reason: no_price or stale_price (no daily close in the last 7 days, for example OTC or halted stocks), no_shares or stale_shares (no cover-page share count within about 400 days, common for companies whose cover lists several share classes separately, such as GOOGL/GOOG, BRK or META), foreign_filer (a Form 20-F filer: the US listing is usually ADSs and the ADS ratio is not in SEC data), shares_mismatch (the cover-page share count does not match the listed shares: 13F institutions report holding more than 1.5 times the cover-page shares, which points to several share classes or ADSs, or the company has two or more traded common lines whose latest closes differ by more than 1.25 times, such as multi-fund ETP trusts like ProShares Trust II that share one cover-page share count) or out_of_range (an implausible value, including a market cap below $1 million); both are null when Livermore has no market cap row for the company. screen_stocks lists companies by market cap. Use get_insider_trades, get_stock_13f_holders, get_financials and get_short_interest for the full lists.
