Definitions and limitations
Copy return models a separate $1,000 buy at the first completed close after disclosure, ignores later sales, subtracts 10 basis points on both entry and exit, and marks to the dated close. The 12-month statistic uses about 252 sessions and a separately counted mature sample. Latest-close medians include only securities with a close matching SPY on the date shown, so the priced sample changes as coverage improves. Unpriced and immature rows are excluded from each denominator. No statistic here predicts future results.
