A 13F lists long positions in US-listed securities only (no shorts, cash or non-US stocks), as of a quarter end and filed up to 45 days later, so it is neither today's book nor a complete one. Share counts are as filed: a stock split changes them with no trade. ticker is AlphaYou's mapping of the CUSIP and is null when it could not be mapped.",
