Read this: Backtested on the CURRENT S&P 500 membership (survivorship bias) — live returns will likely be below these figures. The live basket (forward-looking) is unaffected; only these historical stats carry the caveat. US large-cap, ~16yr mostly-bull sample. Not advice. The 12-1 momentum signal itself is a validated edge (alpha t=2.8, beat SPY 12/16 yrs) — but the headline CAGR is backtest, survivorship-flattered. The live basket below is forward-looking.
