"Holding Period (yrs)" is the latest uninterrupted holding duration, calculated by dividing continuous reported quarters by 4.
Cost basis is an estimate and can differ materially from the actual cost, especially in edge cases.
Cost basis estimate: from the latest uninterrupted holding period, new or increased shares are added to the cost pool at the report price; reductions remove shares at the then-average cost. Example: buy 100 shares at $10 in Q1 and add 50 shares at $16 in Q2, estimated cost basis is (100 x 10 + 50 x 16) / 150 = $12 per share.
Return shows estimated dollar return on top and percentage return below. It uses current price when available, otherwise report price.
