Research, not advice. Past performance does not predict future results. Universe is true point-in-time S&P 500 membership — only stocks actually in the index on the rebalance date are eligible. Live universe loaded from iShares Core S&P 500 ETF (IVV) holdings. Residual survivorship in the underlying price panel is corrected via Monte-Carlo synthetic-delisting overlay (α=4 %/yr) which still preserves +24pp edge over SPY at the median.
