How a book is built

Step 01Screen the universe

The S&P 500 ex-financials, ex-real-estate, screened on price, size and drawdown into a candidate pool.

Live books

The books as they stand now, struck from the latest forecast run. Equal weight at each fill, long only, no costs — the same construction the study above tests, running forward instead of backward.
