Every 13F line is stored as filed; entities of a house are summed; a line whose value contradicts its share count is set aside (excluded), a value in thousands is read in dollars (unitFixed), a share count filed after a split that followed the report date is read at its date (splitFixed), a table larger than the filer's book is not published (suspect). coverage: a floor until the wave of the due quarter is read. ?view=directory: compact directory (key, name, logo, value, style). ?view=performance&period=quarter|year|3y|5y&order=best|worst&limit=: active managers ranked by what the AI-stock portfolio they declared at the start of each quarter, held unchanged to its end (adjusted closes), returned, chained from quarter to quarter — never the change in declared value; return and vsBenchmark (against SMH) as fractions, aiBook = value priced at the start of the last quarter, criteria (at least $250M in these stocks, five positions, none above half, 95% priced), median, eligible, windows (houses read and reasons for exclusion by quarter).
