9 of these positions have a value-scale error in the underlying SEC filing (an entry or exit price ≥25× off the rest of the holding), so their return is unreliable. They are marked data error below and excluded from the stats above, but their quarter-by-quarter filing history is still attached — open History on any row to see it exactly as filed.
