S&P 500, 2011–2026 | 200-Week Moving Average Backtesting
Data Source: S&P 500 historical prices and fundamental data (FCF yield), 2011–2026.
Signal Definition: Buy signals generated when the S&P 500 closes above its 200-week moving average. 3,370 total crossings identified. Hold 12 months, then exit or re-enter if signal changes.
FCF Filter: Each crossing is tagged with the FCF yield of the index at signal time. Buckets are inclusive (e.g., "3–5%" means ≥3% and <5%). Positive & Growing, Positive & Declining, and Positive (trend unknown) reflect whether FCF was increasing or decreasing in the months leading up to the signal.
Returns: Median 12-month total return (price appreciation + dividends) following each signal. Win rate is the percentage of signals with positive 12-month returns.
Statistical Significance: p-values derived from binomial test of win rate vs. 50% null hypothesis. Green indicates p < 0.05 (strong evidence of edge); yellow indicates p < 0.10 (marginal evidence).
