Every daily top-10, frozen when it printed and checked against SPY. Losing days included.

At each US market close the six-factor composite produces a ranking. We write the top 10 down — symbol, rank, score, price — and never touch the row again. The next session we record what the price did and what SPY did over the same two closes. Entries are never re-ranked, back-filled or removed, so what is here is what was published on the day, whichever way it went.
