Prices are end-of-day closes, and fundamentals are the companies' last annual figures from their SEC filings: a − or + in the table is a fact of the filing or the close, not a forecast. Market value is the company-level figure at the last close. Counts are of records OQRO holds, by their date; insider history since 2006 comes from the SEC's insider transactions data sets and every filing since. Planned sales under a 10b5-1 plan are counted like other sales.
