⚠ 61 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.

Entry/exit prices and returns are split-adjusted to today's share basis.
The quarter-by-quarter history shows prices exactly as filed with the SEC, so a pre-split
quarter's price will look higher than the split-adjusted entry above.
