How to read this
Backtested, not live: the model portfolio is one fixed rule re-run at each month-end since 2016 with next-open fills and 5 basis points per unit of turnover, on a universe assembled in 2026 knowing which names won, so read the gap to holding rather than the level. Educational publication, not investment advice; identical for everyone; past performance does not predict future results.
Hesper Atlas is an educational publication, not investment advice. The portfolio is one rules-based construction, identical for everyone, and knows nothing about your situation. Data: end-of-day. Read the terms.
